Abstract. Taking into account the new data presented
in this paper, the tribe Cerambycini in the fauna of
Asia contains almost 60 genus-group taxa and about
335 species, being the largest compared to the faunas
of the other parts of the world. Serious problems in the
development of a reasonable supraspecific classification
of the tribe are noted. Reviews of such taxonomically
confused genera as Elydnus Pascoe, 1869, Imbrius Pascoe,
1866, Zatrephus Pascoe, 1857, and Zegriades Pascoe, 1869,
as well as keys to their constituent species are given. e
following new genera and species are described, two new
statuses change and new combinations are established:
Falsopachydissus gen. n., F. foveiscapus (Holzschuh,
2011),comb.n., Mimimbriusgen.n., M.dembickyisp.n.
(Southern ailand), M. geminatus (Holzschuh,

reviewed, with keys to their species given. e following
new species are described: Dymasius makarovi sp. n.
(Western Malaysia), D. murzinisp. n. (Sri Lanka),
Elydnus barclayi sp. n. (Southern ailand and Western
Malaysia), E. tatianaesp. n. (Vietnam), E. vitaliisp. n.
(Vietnam), Imbrius fedorenkoisp.n. (Southern Vietnam),
I.klimenkoisp.n. (Eastern Malaysia), I.solodovnikovisp.n.
(Eastern Malaysia), Massicus ivanisp. n. (Eastern
Malaysia), M. valentinae sp. n. (Western Malaysia),
Sebasmia indochinensis sp. n. (ailand and Vietnam),
Zatrephus golovatchisp.n. (Southern Vietnam), Zegriades
olemehli sp. n. (Eastern Malaysia). e genus Sebasmia
Pascoe, 1859 is reported from Indochina for the first time.
New records of a number of species from other genera
are given as well, thus one way or another expanding
their distribution areas, sometimes very significantly
so. Provisional considerations on the taxonomy of the
genus Pachydissus Newman, 1838 and on the systematic
position of Plavichydissus Pic, 1946 are presented. Based
on a comparison of the holotypes of Dymasius macilentus
(Pascoe, 1859) and D. strigosus J. omson, 1864, their
synonymy traditionally used in the literature is questioned
as requiring indisputable evidence. e lectotype male of
Dymasius minor Gahan, 1906 is designated. Abundant
pictures of the species studied, including numerous type
specimens, are provided.

Introduction
Taking into account the new data presented in this
paper, the Asian fauna of the tribe Cerambycini Latreille,
1802 contains almost 60 genus-group taxa and about
335species, being the largest compared to the faunas of the
other parts of the world.
e tribe is generally characterized by a very
considerable morphological diversity, on the one hand,
and by very similar or identical morphological structures
in these or those component groups, on the other. All this
makes it extremely difficult any clear differential diagnoses
of various genus-group taxa to be worked out and poses
serious problems in the development of a reasonable
supraspecific classification of the tribe.
An extensive range of questions pertaining to the
systematics and morphology of various representatives
of the tribe were recently discussed by the author at the
15th Congress of the Russian Entomological Society
[Miroshnikov, 2017]. Many of the ideas expressed there
have been implemented in one way or another in the
present paper.
A detailed study of a highly rich and diverse material
amassed by the author, partly through the invaluable
assistance of numerous colleagues and friends, has allowed
to reconsider the species composition and provide reviews
of such taxonomically confused genera as Elydnus Pascoe,
1869, Imbrius Pascoe, 1866, Zatrephus Pascoe, 1857 and
Zegriades Pascoe, 1869; to describe and revise four new
genera; to discuss some aspects of the systematics of the
genera Dymasius J. omson, 1864, Massicus Pascoe,
1867, Pachydissus Newman, 1838 and their individual
representatives; to describe sixteen new species belonging
to nine genera, including two new ones; to clarify or
expand, partly very significantly, the distribution areas of a
number of species; and to present some other new data on
little-known forms.
No complete systematic list of the genus-group taxa
of Cerambycini is available in the modern literature. Nor
even the exact number of cerambycine genera and species
is known for the fauna of Asia. In the present paper, this
information is not arranged in alphabetic order, but is given
in a way that seems most convenient for a discussion and
corresponding taxonomic conclusions. e species lists
in the generic accounts are given, as far as possible, in
systematic order.
I have properly remounted many of the type
specimens kept in various museums in order to take high-
quality photographs of both their habitus and individual
taxonomically important details. erefore, in the present
work, the pictures of these or those types may differ to
some degree in appearance from those available in previous
publications, including original ones.
Given the various new records of these or those
species generally from Indochina as presented in this paper,
the Malay Peninsula, from where some of such records are
known, is taken here as its southern extremity.

Results and discussion
Tribe Cerambycini Latreille, 1802
Genus Imbrius Pascoe, 1866
Imbrius Pascoe, 1866b: 528. Pascoe, 1869: 518; Lacordaire,
1868: 261 (syn. pro Dymasius); Gemminger, 1872: 2803 (syn. pro
Dymasius); Aurivillius, 1912: 59; Hüdepohl, 1990a: 65; Heffern,
2013: 10.
Type species: Imbrius lineatus Pascoe, 1866, by
subsequent designation [Pascoe, 1869].
Diagnosis. is genus differs from all related and
other Asian genera of the tribe by the peculiar structure of
the pronotum, namely, the combination of certain features
of its shape, sculpture and setation, all being more or less
similar in species of the genus, as in Figs31–54.
e pronotum of Imbrius is clearly or at least slightly/
barely, but always longitudinal, more or less broadly
rounded or obtusely angulate in the middle part on the
sides, at the apex insignificantly narrower than at the
base; the sculptural formations in the apical one-third
are sharply delimited posteriorly by symmetrical, usually
arcuate ledges creating two (very rarely three) protrusions
near the midline, these usually being well-expressed, right-
or obtuse-angled, sometimes sharpened and directed
backwards, in front with a median, often longitudinal,
more or less clear tubercle; the apex of the pronotum at
the midline also has two symmetrical, more or less clear,
usually right- or obtuse-angled, small protrusions or a
single, transverse, truncate one; the remaining disc surface
covered with coarse, very coarse or more smooth tubercles
and folds of various shapes, but is devoid of folds that are
strongly extended in one direction or another; with a more
or less strongly developed setation forming separate and
different shapes, but neither long, sometimes partly fused,
symmetrical bundles nor spots, often missing almost
entirely or mostly on the disc, especially in its middle area;
the setation never forms any obvious bands all or almost all
along the pronotum.
Imbrius is also characterized by the following
features, the combination of which makes it even more
distinct compared to the other genera of the tribe:
head comparatively short, usually with a deep, broad,
longitudinal groove both between dorsal lobes of eyes
and on vertex; eyes well-developed, more or less strongly
convex; antennae of male different both in length and
structure of antennomeres, sometimes much longer than
body and with many antennomeres strongly elongated, but
in most cases moderately long, with less strongly elongated
antennomeres; male antennomeres3–5 or 3–4 in the vast
majority of cases more or less inflated in apical parts, length
ratios of antennomeres differing, antennomeres1 and 3–5
can be comparatively short and insignificantly different
in length, antennomeres 6–10 moderately broadened
towards apex, their apical inner angle sometimes with a
clear spine, but thereby last antennomere apically of usual
structure, not extended into a sharp spine; pronotum
generally rounded or obtusely angulate in outline on
sides, but can show separate protrusions formed by a very
coarse sculpture, yet without clear lateral tubercles; elytra
moderately, sometimes strongly elongated, without distinct
longitudinal ribs, with both a relatively rough and very
small, double, very contrastingly differing puncturation,
as in Figs 64–66, apical sutural angle usually more or
less straight, but sometimes sharpened or produced into
a long tooth; recumbent setation of elytra entirely or
mostly monochrome, not velvety, continuous (may be
partly abraded) or, behind middle, with a v-shaped fascia
devoid of dense setae (sometimes appearing like abraded
fragments of setation), also can be in the form of more
or less clear longitudinal strips; prosternum with a well-
expressed transverse groove in front of middle, prosternal
process without lateral dentiform protrusion on sides in
middle part of apical half, as in Figs73–78, usually with a
more or less clear, sometimes very sharp tubercle, but can
also be without it; mesosternal process without tubercle,
between coxae clearly or slightly wider than prosternal
process, sometimes these processes subequal in width
between coxae; legs moderately long, femora claviform,
both femora and tibiae without carina along each side;
genitalia as in Figs82–110, endophallus of various shapes,
thereby can differ very strongly between superficially
very similar species (Figs 102–105; see also below); body
predominantly medium-sized, 13.5–26.5mm in length.
Besides this, some important details of Imbrius
structure are shown below, in the diagnosis of the new
genus, Mimimbriusgen.n., described here.

Diagnosis. is new species is very similar to I.
lineatus, but differs by the structure of the male genitalia,
in particular, the penis being relatively wide near the apex,
narrowed at the very apex through a short cone, as inFigs
82,83 (cf.Figs84,85); by the noticeably wider parameres, in
general the peculiar shape of the apical part of the tegmen,
the wider base of the tegmen, as in Figs87,88 (cf.Figs89,90);
by the more strongly developed, recumbent, light setation
of the pronotum disc, as in Figs 31–33 (cf. Figs 35–38);
the usually less strongly expressed, median, longitudinal
tubercle near the apex of the pronotum, as in Figs31–33
(cf. Figs 35–38); the somewhat denser, recumbent, light
setation of the prosternum between the constriction at
its apex and the anterior border of the coxal cavities, as in
Figs39, 40 (cf. Figs 41, 42); the usually denser setation of
the apical part of the mesosternum, and often by the less
clearly expressed longitudinal strips of dense, recumbent,
light setae on the elytra. Imbrius solodovnikovi sp. n. can
also be compared to I. similis Hüdepohl, 1990, but differs
clearly by the structure of the pronotum, in particular,
its shape being slightly more longitudinal, the coarser
sculpture, at least so on its disc, and the usually more or
less clearly bidentate median protrusion at the apex; if
longitudinal strips of dense, recumbent, light setae on the
elytra clearly expressed, then these strips being narrower;
the sharper apical tubercle of the prosternal process; the
weakly or barely impressed profemora both on the external
and inner sides near the apex; the structure of the male
genitalia (cf.Figs86,91).
Description. Body length 14.9–22.5mm, humeral width 3.6–
5.2mm, thereby holotype 17.4 and 4mm, respectively. Coloration
of integument mainly combines reddish brown and dark reddish
brown tones; eyes, partly mandibles, head dorsally or, besides this,
partly pronotum black.
Head with well-developed antennal tubercles; with a sharp
median groove between bases of antennae, growing even sharper
between eyes and on vertex, as well as with a very sharp, deep,
oblique groove behind inner part of each of dorsal lobes of eyes;
genae rather short; eyes well-developed, relatively strongly convex;
submentum in basal part with a coarse irregular sculpture, in
apical part strongly impressed, smooth; neck with sharp transverse
folds both ventrally and laterally; antennae of both male and female
usually subequal in length, reaching beyond apex of elytra by last
antennomere, but in female sometimes can only reaching the apex
of elytra; length ratio of antennomeres 1–11 in male (holotype
taken as an example), 30:10: 30: 26: 28: 37: 41: 42: 40: 37:48, in
female (one of the paratypes taken as an example), 31:10: 31: 24:
27: 38: 42: 41: 40: 38: 52; antennomere1 with a heterogeneous,
partly rough, rugose, dense puncturation; antennomere2 subequal
in length and width; male antennomeres 3 and 4 strongly,
5th moderately inflated in apical part; last antennomere with a
distinct appendage.
Pronotum clearly longitudinal, 1.17–1.21 times as long
as width; base 1.10–1.15 times as wide as apex; with a sharp
constriction near apex; on disc with coarse or rough tubercles and
folds, at apex in middle part with two more or less right-angled,
small protrusions, as in Figs31–33; near apex with a clearly, but
not too strongly expressed, usually moderately shiny, longitudinal,
median tubercle usually bearing at least a few, recumbent, light
setae, as in Figs 31–33 (in I. lineatus, median tubercle strongly
expressed, very shiny, completely devoid of recumbent light setae,
as in Figs35–38).
Scutellum strongly narrowed towards apex, triangular, at the
very apex more or less broadly rounded or truncate, but can also
be sharpened.
Elytra in male slightly narrowed towards apex, in female about
parallel-sided, 2.67–2.88 times as long as humeral width; with

process without tubercle dorsally, between coxae slightly or barely
wider than prosternal process; mesosternum partly, metasternum
and sternites with a small dense puncturation; metasternum with
a clear, but not too sharp, median groove; last (visible) sternite at
apex in male with a very clear broad emargination, in female widely
rounded; last (visible) tergite at apex in male truncate, in female
widely rounded.
Legs moderately short; femora claviform; tarsomere 1 very
clearly shorter than tarsomeres2 and3 combined.
Recumbent setation mainly yellow tones, only partly greyish
or greyish yellow; distribution of setation predominantly almost

same as in I. lineatus, but on disc of pronotum comparatively
more strongly developed, thereby on tubercles lateral to midline,
especially in basal part, always with clear fragments of setae
while a fascia near apex less clearly interrupted in area of median
tubercle, as in Figs31–33 (in I.lineatus, tubercles lateral to midline
devoid of setae, as a rule, only rarely with a few setae on tubercles
in basal part just beyond middle; fascia near apex usually very
clearly interrupted in area of median tubercle, as in Figs35–38),
on elytra often forming less strongly expressed, partially confused,
longitudinal strips, as in Figs 4, 5, on prosternum partly denser,
as in Figs39,40; head, pronotum laterally in apical part, pro- and
metasterna partly, abdomen usually at apex, most of antennomeres
in apical part, legs mainly on trochanters with more or less long,
erect, partly suberect, sparse or individual, thin setae.
Genitalia of male as in Figs82, 83, 87,88.
Etymology. I am pleased to dedicate this new species
to my colleague and friend, Dr.Alexey Yu. Solodovnikov,
curator of the Coleoptera collection of the Natural History
Museum of Denmark (University of Copenhagen), who
constantly provides his great and versatile help to my
research. Without his strong support, many of the issues,
including those related to a rapid and safe delivery of
material, would have been much more difficult to solve.

Morphological notes. Body length 16.5–19.8 mm,
humeral width 4.1–4.8 mm, thereby holotype 19.3 and
4.7mm, respectively.
Remarks. is species was described in the following
work: “Catalogue of Longicorn Coleoptera collected in the
Island of Penang by James Lamb, Esq. (PartII.)” [Pascoe,
1866b]. However, BMNH keeps the female type bearing
4 labels: “ J a v a ”, “ Imbrius ephebus Pasc. Type”, “Type” and
“Imbrius ephebus P. Java” (Fig.441). Its length is 19.3mm
(humeral width 4.7mm), which corresponds approximatelly
to the length indicated in the original description (9lines,
i.e. about 19.05mm). I am not aware of any other types.
In a later work, Pascoe [1869: 519] noted the following
distribution area of this species: “Singapore, Java (and
Penang)”. However, the material from “Penang”, as well as
those from other districts of Western Malaysia, are known
from neither BMNH nor any other of the museums whence
material was possible to study.
erefore, taking into account all above, it seems
obvious that Pascoe provided the original description,
based exactly on the specimen kept in BMNH, but for some
reason he falsely indicated its provenance from “Penang”;
the same holds true also for the introductory text of the
first part of the work [Pascoe, 1866a]. In this respect, I
consider that specimen as the holotype by monotypy, and
I define the type locality according to the appropriate label
(“Java”), but not to the original description (“Penang”).
Distribution. Western and Eastern Malaysia,
Indonesia (Java), Singapore.

Diagnosis. is new species seems to be especially
similar to I.simulator, but differs clearly by the structure of
the tegmen, the shape of the apical part of the penis, as in
Figs92,95 (cf. Figs93, 94, 96,97), as well as by the structure
of the pronotum, in particular, the very poorly developed
setation along its sides, the somewhat peculiar sculpture of
the disc, as in Fig.43 (cf.Figs44–46), including the shape
of the folds in the basal part near the midline, the generally
broader and more rounded (not crest-like) folds dorsally,
the predominantly clearly sharper puncturation of the folds,
the generally more delicate, recumbent, light pubescence of
the antennae, the coloration of the elytra with a distinctly
creamy tone, and some other minor features.
Description. Male. Body length 17.1 mm, humeral width
4.3 mm. Coloration of integument mainly combines red-brown,
dark red-brown and red tones; eyes, mandibles partly and
pronotum on disc near apex lateral to median tubercle black.
Head with well-developed antennal tubercles; with a sharp
median groove between bases of antennae, growing even sharper
between eyes and on vertex, as well as with a very sharp, deep,
wide, oblique groove behind inner part of each of dorsal lobes
of eyes; genae moderately short; eyes well-developed, relatively
strongly convex; submentum in basal part with a rough shallow
puncturation, in apical part clearly impressed, smooth; neck
with clear transverse folds both ventrally and laterally; antennae
reaching beyond apex of elytra by last antennomere; length ratio
of antennomeres1–11, 28:9: 31: 27: 28: 31: 38: 41: 40: 37:45;
antennomere1 with a heterogeneous, partly rough, rugose, dense
puncturation; antennomere 2 subequal in length and width;
antennomeres3 and 4 clearly, 5th and 6th moderately inflated in
apical part; last antennomere with a very evident appendage.
Pronotum distinctly longitudinal, 1.17times as long as width,
at base slightly wider than at apex; with a sharp constriction near
apex; on sides angularly broadened towards the middle from
both base and apex; on disc predominantly with coarse, partly
rough tubercles and folds, at apex in middle part with a distinctly
emarginate protrusion; near apex with a sharp, longitudinal,
long, median tubercle; compared to I. simulator (as noted in
Diagnosis partly), tubercles and folds mostly roundish dorsally,
wider, with sharp punctures partly, thereby in basal part lateral
to midline with two symmetrical, short, slightly sinuous, partly
more or less roundish tubercles connected by a transverse, short,
moderately rough fold and behind these tubercles with a median
fold branched in basal part into two partly transverse short folds
(while in I. simulator in apical part lateral to midline with two
pairs of symmetrical relatively narrow folds, these often partially
connected with each other, thereby upper pair clearly or very
clearly coarser, strongly crest-shaped, whereas instead of lower
pair of folds sometimes with one or even two transverse folds;
besides this, median tubercle near apex usually shorter than in new
species, sometimes even very short, somewhat roundish).
Scutellum strongly narrowed towards apex, triangular.
Elytra barely narrowed towards apex, 2.53 times as long
as humeral width; with both a relatively rough and very small,

Diagnosis. Based on external features of the male,
this new species is very similar to I.uniformis, while their
females seem to be identical. However, I.klimenkoisp.n.
differs at least by the structure of the antennae of the male,
in particular, the less strongly inflated antennomeres3–5 in
the apical part, the more numerous, long, erect or suberect
setae on the inner side of antennomeres3–7 or3–8 and,
in most cases, by the somewhat shorter antennae. e
most important differences between I. klimenkoi sp. n.
and I.uniformis lie both in the shape and fine armature
of the endophallus, as in Figs102,103 (cf.Figs104, 105),
as well as in the conformation of the penis and tegmen. In
the new species, the apical part of the penis is wider, as in
Fig.98 (cf.Fig.99), that of the tegmen is also wider and less
strongly elongated, as in Fig.100 (cf.Fig.101), each of the
parameres on the ventral side distal to about 3/4 is more or
less strongly sloping down, thereby the brown coloration of
the parameres noticeably or very clearly fails to reach their
bases, as in Fig.100, whereas in I.uniformis the parameres
are more or less strongly sloping down only behind their
bases on their ventral side so that the entire surface of the
paramers lies in about the same plane, thereby the brown
coloration covers completely each of the parameres and
reaches their bases, as in Fig. 101. Reliable differences
between I. klimenkoi sp. n. and I. uniformis have been
found yet neither in the structure of the female genitalia
nor in general any external features (see Notes below). Only
in the former species are both tergite and sternite8 much
darker (Figs106,107) than in the latter one (Figs108–110),
but possibly this trait is variable, since in some cases there
seem to be transitions in coloration.
Remarks. e attribution of these or those female
specimens to I. uniformis or the new species has been
established, based of the following observations.
Considering that I. uniformis, judging from the original
description, is known from both parts of Malaysia and
that I have at my disposal a male of I.uniformis and one
female (Fig.8) from the same locality (WMalaysia, Perak,
Cameron Highlands, Ringlet), both collected at about
the same time (25.03–3.04.2002 and 26–31.03.2000,
respectively), I have assigned them to the same species.
eir both tergite and sternite8 are coloured clearly light
tones. Identically coloured are both tergite and sternite8
in two females originating from Tanah Rata, located on
the same, Cameron Highlands, as well as in most of the
females from Eastern Malaysia, in particular, from the
Crocker Range (Sabah), the type locality of I. uniformis,
and from Trus Madi Mountain (Sabah). In the female
collected in the latter locality (i.e. Trus Madi Mt.) on
23.03.2012 together with two males of the new species,
including the holotype, as well as in one female from
the same place (27.02.2014) and in another female from
Pensiangan (Sabah), both tergite and sternite8 are equally
strongly darkened. I have preliminarily attributed them
to paratypes of I.klimenkoisp.n. By the character of the
coloration of both tergite and sternite 8 in two females
and one female originating from the Crocker Range and
Trus Madi Mountain, respectively, it appears impossible
to unequivocally assign them to either species. It is quite
obvious that to securely identify females of both species,
further detailed studies are needed.

Etymology. is new species is dedicated to the
memory of late Alexey Alexandrovich Klimenko who
untimely left us (1970–2017), a remarkable Russian
traveller and connoisseur of Coleoptera. His magnificent
collections and other material on some groups of longicorn
beetles from the Oriental Region, especially from Borneo,
which he generously shared with me, formed the basis for a
number of important taxonomic findings and the discovery
of new, sometimes surprising taxa described in this work.
Distribution. Eastern Malaysia.

Genus Mimimbrius Miroshnikov, gen. n.
Type species: Cerambyx micaceus Pascoe, 1858.
Diagnosis. is new genus, whose representatives
have hitherto been assigned to the genus Imbrius, differs very
clearly from the latter by the much more strongly developed
eyes noticeably reaching beyond the anterior border of the
bases of the antennae and strongly connivent on the ventral
side of the head, as in Figs 70–72 (cf.Figs67–69); the much
larger ocelli, as in Figs 70–72 (cf. Figs 67–69) (see also
Remarks below); the presence of a carina along each side,
both external and inner, of the femora and tibiae, as in
Figs25–30; the structure of the prosternal process which
has a very strongly developed, lateral, dentiform protrusion
on each side in the middle part of the apical half, as indicated
by arrows in Figs79–81 (cf.Figs73–78); the rather peculiar
setation of the elytra, as in Figs 25, 27–30; the more or
less homogeneous puncturation, as in Figs61–63 (but not

double that would vary radically in size) (cf.Figs64–66);
the very similar structure of the antennae and elytra; and
on the average a smaller body, 11–14.1mm in length.
Besides this, even though the general structure of
the pronotum and, in particular, the sculpture of its
disc in Mimimbrius gen.n. resemble those of Imbrius,
the former genus is sufficiently distinct from the latter.
us, in the new genus, the apical margin of the
pronotum at the midline is clearly drawn into a more
or less rounded angle, as in Figs 55–60, 115–118; the
ledges sharply delimiting posteriorly and lateral to the
midline a sculptural formation in the apical third of the
pronotum (Figs 55–60, 115–118) that creates usually
less strongly curved and often more vertical lines that
grow increasingly vague towards the lateral margin of
the pronotum, as in Figs55–60, 115–118; the disc of the
pronotum is sculptured this or that way (see below), but
creates no clearly symmetrical, longitudinal, individual
folds lateral to the midline, whereas in Imbrius the
apical margin of the pronotum at the midline is
bidentate or with a truncate, more or less broad,
single projection, as in Figs 31–38, 43–54; the ledges
sharply delimit posteriorly and lateral to the midline
a sculptural formation in the apical third of the
pronotum (Figs31–38, 43–54) that usually creates more
horizontal and often more strongly curved lines which
largely remain clear-cut until the very lateral margins
on both sides, as in Figs 31–38, 43–54, the disc of the
pronotum lateral to the midline, at least so in the basal
part, usually with clearly or quite symmetrical, often
longitudinal, individual or partly confluent folds.
In Mimimbriusgen.n., the head is with a more or less
deep groove between the bases of the antennae and the
eyes, as well as on the vertex; the eyes always clearly reach
forward beyond bases of antennae, considerably embracing
them (while in Imbrius the anterior border of the eyes is
located about the same level as the anterior border of the
antennal cavities); the antennae of the male are slightly
longer than the body, at least reaching beyond the apex
of the elytra by the last antennomere, in the female hardly
shorter or barely longer than the elytra, can also be subequal
to body length; antennomeres 3–5 of the male are non-
inflated, resemble those in the female; antennomere3 in
both sexes barely shorter than the1st; antennomeres6–10
moderalety serrate, their apical inner angle without spine
(while in Imbrius the length of the antennae, especially in
the male, is very clearly variable, thereby the antennae of the
male can be much longer than the body, antennomeres3–5
of the male in the vast majority of cases one way or another
inflated, in the remaining cases at least antennomere 3
more or less clearly thickened at the apex, the length ratio of
antennomeres1 and3 very clearly variable, antennomere3
from barely to much longer than the1st and, as it seems,
cannot be shorter than the latter; the apical inner angle
of antennomeres 6–10 sometimes with a clear spine);
the elytra with a moderately small, more or less dense,
relatively homogeneous puncturation gradually decreasing
from base towards apex or, besides this, partly with larger,
but not coarse, denser or sparser punctures; the apical
sutural angle is either obtuse or rounded, either without
tooth or with a weakly expressed denticle (while in Imbrius
the elytra with a double puncturation radically differing in
size, as in Figs 64–66, apical sutural angle can be sharpened
or with a long tooth); the recumbent setation of the elytra,
due to variously located and differently dense setae, forms
a peculiar pattern, as in Figs 25, 27–30 (while in Imbrius
the setation of the elytra, whatever it is like, does not show
features similar to those in the new genus); the longitudinal
carinae on the femora and tibiae extending over entire
length, from base to apex, and located almost completely
in the middle part of both external and inner sides, can also
be partly less strongly expressed or indistinct, especially on
the metafemora (a similar carina is also characteristic of
certain species of Dymasius J.omson, 1864, Xoanodera
Pascoe, 1857 (in the latter genus, the carina can be present
only on femora), of some Derolus Gahan, 1890 and several
other genera as well, but at least on the femora it is shifted
towards their lower margin on both sides).
Remarks. It is noteworthy that in some representatives
of the tribe, e.g., Sebasmia Pascoe, 1859, the eyes can be
as strongly developed as in the new genus, but the size of
their ocelli is comparatively smaller. is strengthens the
taxonomic significance of that feature, at least so as regards
Mimimbrius gen. n. and Imbrius.
Etymology. In Greek, mimos (απομίμηση) means
“imitating, similar”, derived directly from Imbrius Pascoe,
1866, to emphasize the resemblance and to mean “imitating
Imbrius”.

Diagnosis. is new species is very similar to
M. subargenteuscomb. n., but differs clearly by the
somewhat peculiar sculpture and setation of the pronotum
disc, as in Figs58, 115, as well as by features of the setation
on the head between and behind the eyes, as in Fig.115,
the presence of a partly dense setation on antennomere1,
as in Fig. 115, the generally the sparser, recumbent, light
setation of the elytra, as in Fig. 30, a somewhat less deep
transverse groove of the prosternum in front of its middle,
the genitalia of the male, in particular, the shape of the
penis apex, as in Fig.111 (cf.Figs28, 29, 55–57, 112–114,
116–118).

genus; genae relatively short; submentum with a heterogeneous,
rough and coarse sculpture; behind eyes with sharp transverse
folds both laterally and ventrally; antennae slightly longer than
body, reaching the apex of elytra by apical part of penultimate
antennomere; length ratio of antennomeres1–11, 20:6: 21: 16:
21: 28: 32: 31: 31: 30: 40; antennomere1 mainly with a somewhat

somewhat flattened dorsally, irregular folds and tubercles, as in
Fig.58 (inM.subargenteuscomb. n., coarse folds mainly or fully
transverse, rounded dorsally, not flattened, as in Figs55–57), near
apex in median area partly with fragments of clear, but not too
sharp, relatively small puncturation (inM.subargenteuscomb.n.,
puncturation in this place generally smaller, but at least partly
noticeably sharper); sculptural formation in apical one-third of
disc, compared to M.subargenteuscomb.n., less strongly elevated,
with a clearly less expressed median tubercle.

as long as humeral width; with a small, somewhat heterogeneous,
more or less dense puncturation; apical external angle widely
rounded, sutural angle almost right.

yellow, of venter mainly greyish; dense setae between upper lobes of
eyes forming two symmetrical, ver y well-expressed, clearly divided,
longitudinal strips, as in Fig. 115 (in M. subargenteuscomb. n.,
these strips significantly narrower and less strongly expressed,
as in Figs116–118); dense setae on pronotum forming relatively
symmetrical individual fragments only along sides, near both apex
and base in middle part, thereby near apex fragments much narrower
than in M.subargenteuscomb.n.; setation of elytra peculiar, as in
Fig.30, only partly masking puncturation; antennomere1 partly,
predominantly on inner side, with dense yellow setae (Fig. 115)
while this antennomere in M. subargenteuscomb. n. only with
sparse greyish setae (Figs 116–118); head, pronotum laterally,

Hüdepohl, 1990a: 75; 1998: 213; Vives, 2005: 245; Heffern,
2013:10.
Type species: Elydnus amictus Pascoe, 1869, by
subsequent designation [Gressitt, Rondon, 1970].
Diagnosis. is genus seems to differ clearly from all
other Asian genera of the tribe, including closely related
ones, by the unique structure of antennomeres4 and5 of
the male, namely, the presence at the base of each of these
antennomeres of a very peculiar area with a particular
sculpture and, in the vast majority of cases, bearing
numerous pores, in addition the area is either devoid of
long erect setae or sometimes with individual such setae,
as in Figs131–144. In representatives of some genera of the
tribe, which are generally rather dissimilar morphologically
to Elydnus, for example, Diorthus Gahan, 1891, there is also
a somewhat peculiar structure of antennomeres4 and5 or
3–5, as in Fig.147, but this is very clearly different from the
genus in question.
Besides this, Elydnus is characterized by the following
features, the combination of which makes it even more
distinct compared to the other contribal genera: head
with moderately developed eyes; antennae of male much
longer than body, reaching beyond apex of elytra by
antennomere8or 9 (Color plate 1: 119–121, 123, Fig.126), in
female always longer than elytra, reaching beyond their apex
by antennomere9 or 10, as in Color plate 1:122, Color plate2:
128, antennomere1 with neither a very coarse sculpture (in
the form of very strong folds, grooves, impressions, processes,
etc.), nor a cicatrix, antennomere 2 distinctly or strongly
transverse, apical external angle of antennomeres 6–10
insignificantly broadened at apex, apical inner angle of
the same antennomeres without spine, last antennomere
apically can be neither strongly sharpened nor extended
into a long sharp spine (Figs 145–146), antennomeres 3
and4 or only 3rd of male in apical part inflated, while last
antennomere of male not more than 1.9 times as long
as penultimate antennomere; pronotum from slightly
longitudinal to barely transverse, widely rounded on sides,
with a rather diverse, coarse or very coarse sculpture, as
in Figs171–182, but never only or mainly with transverse
folds; elytra moderately elongated, starting with base mostly
about parallel-sided or slightly broadened behind the
middle; each elytron apically more or less obliquely truncate
or slightly emarginate, with an about straight or obtuse,
apical, external angle, while sutural angle with a more or
less weakly developed denticle; velvet setation of elytra
shimmering and with light or dark fragments of very dense
recumbent setae forming a peculiar pattern, as in Color plate
1:119–124, Color plate 2: 125–126, 128, thereby this being
very similar among all members of the genus; prosternal
process with a clear or well-developed tubercle; mesosternal
process without tubercle; metatibia at anterior margin from
strongly concave to more straight, but at least barely concave
(in any case, not clearly straight), as in Figs159–170; protibia
predominantly with a dense or very dense light setation both
on inner side and at posterior margin, mainly in apical part;
femora and tibiae without longitudinal carina; tarsomere1
clearly shorter than tarsomeres 2 and 3 combined; body
from medium- to large-sized, in length 18.4–31mm.
Remarks. Originally, Elydnus was described as a
separate genus with two species: E. amictus Pascoe, 1869
(Sarawak) and E. sericatus Pascoe, 1869 (Banda Island)
[Pascoe, 1869]. After Gahan [1891] had considered as a
subgenus (“section”) of the genus Dymasius J. omson,
1864, this was accepted also by Aurivillius [1912], and
Gressitt and Rondon [1970]. But the type species of Elydnus
was designated only by the latter authors.
Hüdepohl [1989a] was the first to draw attention to the
unique feature of E.amictus: structure of antennomeres4
and5 of the male. Discussing the taxonomic significance
of this feature, he [Hüdepohl, 1990a: 75–76] noted
the following: “Pascoe's Elydnus amictus, 1869, shows
a very peculiar character in the male antennae: there
are poriferous pits at the bases of the fourth and fifth
segments – something uncommon in Cerambycidae and
not mentioned by Pascoe or Gahan. Even if this character
might be of importance on specific level only, it seems
useful to maintain Elydnus as a genus till the situation
is cleared up.” However, Hüdepohl [1989a, b] thereby
described three new species in this genus, the males of
which, unlike E.amictus, do not show the above structural
features of male antennomeres 4 and 5. Another three
species were added to Elydnus, also dissimilar in the
structure of the antennae and some other features from
E.amictus [Holzschuh, 2003; Vives, 2005; Vives, Heffern,
2016]. Besides this, a few more species clearly distinct from
E.amictus were later assigned to Elydnus (asasubgenus of
Dymasius), described at different times [Gressitt, Rondon,
1970; Kusama, Takakuwa, 1984; Nakamura et al., 1992;
Nga et al., 2014 and others]. Most recently, also Aeolesthes

encompassing 14different species.
e discovery of yet new species generally very similar
to E.amictus, including the structure of the male antennae,
like those described below, shows a decisive importance
of the unique character considered above in the diagnosis
of the genus. In addition, that feature proves to be to
some degree species-specific, this only reinforcing its
high taxonomic significance. e female, unlike the male,
differs clearly from other genera, as noted above, only by
a combination of traits, among which the most important
seem to be elytra setation, its strong similarity between all
species and the structure of the metatibia.
In any case, the isolation of the genus Elydnus in
the composition proposed here is rather obvious and it
seems to be the best expressed against the background of
very complex problems in the development of diagnoses
in a number of other genus-group taxa within the tribe
Cerambycini.
A detailed study of species excluded from Elydnus
allows to propose the following solution for establishing
their systematic positions. For species similar to “Elydnus”
pascoei (Gahan, 1891) and “E.” sericatus, which seem to
be morphologically somewhat peculiar and represent a
rather homogeneous group, a new genus is described (see
below). e remaining species, namely, “Elydnus” vitreus
(Pascoe, 1885) (Figs 200, 453), “E.” kisanus (Matsushita,
1935), “E.” hirayamai (Matsushita, 1941) and “E.” simplex
(Gressitt et Rondon, 1970), are siggested to be assigned to
the genus Dymasius without a subgeneric placement, at
least so pending a revision of this genus.
us, only five species are considered in Elydnus, three
of which are described as new, while one taxon gets a full
species status.
Distribution. Oriental realm.

Morphological notes. Body length 18.4–29.1 mm,
humeral width 4.05–7 mm, thereby holotype 22.7 and

Remarks. Based on the original description, as well
as the material kept in the BMNH, it seems that only the
holotype by monotypy is to be distinguished.
Distribution. Singapore, Eastern Malaysia, Brunei,
Philippines; very likely also the territory of Indonesia in
Borneo; the record in Myanmar [Hüdepohl, 1998] is likely
to be attributed to the next new species.

Diagnosis. is new species is very similar to
E. amictus, but differs by the obliterated sculpture of the
base of antennomeres 4 and 5 of the male, as in Figs 134,
135, 140–142, the shortened antennomere 5 in relation to
antennomere 4 at least in the male, as in Figs 134, 135, the
narrower submentum, the somewhat peculiar structure of
the tegmen, as in Fig. 154, the darker penis and tergite8, as in
Figs150, 151, 157, 158 (cf.Figs131–133, 138, 139, 148, 149,
152, 153, 155, 156). Besides this, E. barclayi sp.n. has light
fragments of recumbent setation on the elytra with clearly
golden tones (Color plate 1:123), while in E. amictus such
fragments in the vast majority of cases are silvery tones (Color
plate 1:119–122). A new species can also be compared to
E.rufulus Holzschuh, 2016,stat.n., but differs by a generally
peculiar coloration, as in Color plate 1:123 (cf.Color plate
1:124), as well as in the structure of the area at the base of
male antennomeres4 and 5, namely, the presence of very
clear and numerous pores it supports (Figs 134, 135,
140–142) (see also Remarks to E.rufulus below).
Description. Male. Body length 20.8–24.9 mm, humeral
width 4.7–6.2 mm, thereby holotype largest. Coloration of
integument mainly combines reddish-brown and dark reddish-
brown tones; eyes, partly mandibles, disc of pronotum or, besides
this, partly prosternum black.
Head with well-developed antennal tubercles; with a sharp
median groove between bases of antennae, eyes and on vertex;
eyes moderately convex; longitudinal diameter of lower lobe
of eye 1.64–1.76 times as long as genae; submentum only 2.34–
2.42 times as wide as long (in E. amictus, 2.68–2.89 times, as
a rule), with a heterogeneous, coarse or rough, sparse, in places
small puncturation; neck with sharp transverse folds both ventrally
and laterally; antennae much longer than body, reaching beyond
apex of elytra by antennomere8 or barely not reaching it by apex
of this antennomere; length ratio of antennomeres1–11 (holotype
taken as an example), 25:5: 29: 22: 24: 55: 61: 60: 60: 57:100;
antennomere 1 with a clear, heterogeneous, partly somewhat
rough, dense puncturation; antennomere2 distinctly transverse;
antennomeres 3 and 4 moderately inflated in apical part;
antennomeres4 and5 each with a peculiar area at base, this being
characteristic of the genus and showing an obliterated surface with
clear numerous pores, as in Figs134–135, 140–142 (inE.amictus,
e longicorn beetle tribe Cerambycini Latreille, 1802 (Coleoptera: Cerambycidae: Cerambycinae) 183
this peculiar area with a very coarse sculpture, as in Figs131–133,
138, 139), thereby antennomere 5 only 1.10–1.13 times as long
as antennomere4 (in E.amictus, 1.28–1.37 or 1.19–1.36times in
male and female, respectively).
Pronotum barely longitudinal, 1.03–1.05 times as long as
width; base 1.07–1.09 times as wide as apex; with a very sharp
constriction near apex; on disc with very coarse folds, like in
E. amictus, namely, with two longitudinal, long, symmetrical
folds in the middle and irregular, partly sinuous and clearly
transverse, in places symmetrical folds, as in Figs171–172, thereby
predominantly on longitudinal ones with heterogeneous, in places
coarse, partly small, sharp punctures.
Scutellum strongly narrowed towards apex, triangular.
Elytra about parallel-sided, 2.7–2.77times as long as humeral
width; with a very small dense puncturation; apical external angle
about right, well-expressed, sutural angle with a small, but clear
denticle.
Prosternum with a sharp transverse groove in front of
middle, with heterogeneous, coarse or rough, irregular folds;
prosternal process clearly broadened towards apex dorsally, with a
very strong apical tubercle; mesosternal process without tubercle
dorsally, between coxae distinctly wider than prosternal process;
mesosternum partly, metasternum and sternites with a small
dense puncturation; metasternum with a sharp median groove; last
(visible) sternite at apex with a broad, but shallow emargination;
last (visible) tergite truncate apically.
Legs moderately long; protibia, like in E.amictus, very clearly
broadened from base towards apex, somewhat peculiar in shape;
metatibia at anterior margin clearly concave, this characteristic
of the genus, as in Fig.166; tarsomere1 very clearly shorter than
tarsomeres2 and3 combined.
Recumbent setation like in E. amictus, on head dorsally,
pronotum, partly elytra, antennae and legs yellow tones, on venter
mainly greyish; more or less dense setae covering most of head
dorsally, partly basal antennomeres, tibiae, metafemora, tarsi,
on pronotum forming a pattern, as in Figs171, 172; light setae
on elytra partly with a golden tint (in E. amictus, setae partly
in the vast majority of cases with a silvery tint), combined with
brown and dark brown setae and generally forming an iridescent
pattern characteristic of the genus, as in Color plate 1:123; head,
pronotum on disc and laterally, metasternum, partly abdomen,
including at apex, legs mainly on trochanters with more or less
long, erect, partly suberect, sparse or individual, thin setae; erect
setation of antennae heterogeneous, almost same as in other
representatives of the genus: antennomeres1–8, except for base of
antennomeres4 and5, predominantly on inner and, partly, venral
sides with numerous, short, erect, somewhat oblique, thin setae in
the form of a sparse gentle brush (subsequent antennomeres with
even shorter erect setae), thereby antennomeres2–10 at apex with
individual, long, thin setae directed towards apex of antennae and
individual, long, erect setae in apical part ventrally.
Genitalia as in Figs 150, 151, 154, 157,158.
Etymology. I am pleased to dedicate this new species
to my colleague, Dr.MaxwellV.L.Barclay, the curator of the
collection of Coleoptera at the Natural History Museum,
London, United Kingdom, who, over a number of years,
has kindly provided his great assistance to my study of the
museum material.

Elydnus amictus rufulus Holzschuh, 2016: 110. Type locality:
Indonesia, MentawaiIsls., SSiberutIsl., Salapa vill. env. [01°21’S/

Material. ♂, holotype (cCH) (photograph; Color plate 1:124).
Morphological notes. Holotype male. Body length
22mm (according to the original description).
Remarks. Based both on the original description
[Holzschuh, 2016] and high-quality photograph (Color
plate 1: 124) of the holotype (received through the courtesy
of Mr. Luboš Dembický, Brno, Czech Republic) I have
studied, as well as taking into account the structural
features of other representatives of the genus, this taxon, in
my opinion, is to be considered as a separate species. us,
Elydnus rufulus Holzschuh, 2016,stat.n.
Considering the original description, the peculiar area
at the base of male antennomeres4 and5 is devoid of pores
[Holzschuh, 2016, p. 110: “das Fehlen eines Porenfeldes
auf der Innenseite der Basis der Fühlerglieder4 und5”], in
contrast to all other representatives of the genus. However,
the area proper on both these antennomeres, based on the
picture (Color plate 1:124), is distinguished clearly enough.
At the same time, it seems noteworthy, and as noted
above, the presence of a peculiar area at the base of each
of male antennomeres4 and 5 bearing more or less clear
and numerous pores is highly characteristic of Elydnus.
In this connection, this structure requires revision in
E.rufulusstat.n., as the pores could have been overlooked,
but at least some individual pores are actually present,
albeit poorly-visible.
Distribution. Indonesia (Mentawai Islands, Siberut
Island).

Diagnosis. is new species resembles E. amictus
Pascoe, 1869 and E.barclayisp.n., but differs very clearly
from both by the very peculiar sculpture of the pronotum
disc, the character of its setation, as in Fig. 180, the
structure of antennomeres4 and5 of the male, including
the sculpture in the area at their bases, as in Figs136,143,
the peculiar, non-inflated shape of antennomere 4 of
the male, as in Fig. 136, the shorter antennae of the
female, on the average a larger body and some other
characteristics (cf. Figs 131–135, 138–142, 171–178).
Elydnus tatianae sp. n. is very similar to another new
species, E.vitaliisp.n., described below, but differs by the
features noted in the the latter’s diagnosis.
Description. Body length 24–31 mm, humeral width
6–7.7 mm, thereby holotype largest. Coloration of integument
mainly combines reddish brown and dark reddish brown tones;
head predominantly behind antennal tubercles, eyes, partly
mandibles, disc of pronotum entirely or mostly, prosternum at
apex, profemora partly on external side black.
Head with well-developed antennal tubercles; with a sharp
median groove between bases of antennae, eyes and on vertex;
eyes moderately convex; longitudinal diameter of lower lobe of
eye 1.2–1.36times as long as genae; submentum 2.7–3.2times as
wide as long, with a very heterogeneous puncturation; neck with
sharp transverse folds both ventrally and laterally; antennae of
male much longer than body, reaching beyond apex of elytra by

65: 66 : 65 : 63: 115, in female, 4 : 30: 20 : 25 : 32 : 32: 30 :
29: 27:34; antennomere1 of male with a heterogeneous, mostly
rough, partly rugose, dense puncturation, in about apical one-third
on inner side clearly narrowed towards apex, in female with a small
dense puncturation, narrowed towards apex, like in male, but less
clearly; antennomere 2 distinctly transverse; antennomere 3 of
male moderately inflated in apical part; antennomere4 closer to
cylindrical in shape, thereby its base about 1.3 times as wide as
that of antennomere3; antennomeres4 and5 each with a peculiar
area at base, this being characteristic of the genus and showing a
moderately rough, but not too sharp sculpture and clear numerous
pores, as in Figs136,143.
Pronotum subequal in length and width, at base slightly wider
than at apex; with a very sharp constriction near apex; on disc with
longitudinal, very coarse, sinuous folds and two longitudinal, wide,
coarsest and highest near middle, symmetrical elevations in middle
part, each of which on external side in front of middle with a very
strong protrusion connected to ventral margin of nearest fold, as
in Fig.180, thereby elevations with a small dense puncturation and
individual coarse punctures.
Scutellum strongly narrowed towards apex, triangular, can be
clearly truncate apically.
Elytra about parallel-sided, 2.56–2.59 times as long as
humeral width; with a very small dense puncturation; apical
external angle subobtuse, well-expressed, sutural angle with a
small denticle, thereby both angles masked under a dense setation.

mesosternum partly, metasternum and sternites with a small dense
puncturation; metasternum with a clear, not sharp median groove;
last (visible) sternite at apex in male with a well-expressed obtuse-
angled emargination, in female widely rounded; last (visible)
tergite at apex truncate both in male and female.
Legs moderately long; protibia very clearly broadened from
base towards apex; metatibia at anterior margin, in comparison
with other species of genus, generally the least concave, but still
not too straight, as in Figs 169, 170; tarsomere 1 very clearly
shorter than tarsomeres2 and3 combined.
Recumbent setation similar to that of other species of the
genus, on head dorsally, pronotum, partly elytra, antennae and
legs yellow and reddish yellow tones, partly with golden tint, on
venter mainly greyish; more or less dense setae covering most of
head dorasally, partly basal antennomeres, tibiae, metafemora,
tarsi, on pronotum forming a pattern, as in Fig. 180; light setae
on elytra combined with red-brown setae and generally forming
an iridescent pattern characteristic of the genus, as in Color
plate2:126, thereby in area of humeri distinguished by paler tint;
head, pronotum on disc and laterally, partly meso- and metasterna,
abdomen mainly at apex, legs mostly on trochanters and coxae
with more or less long, erect, partly suberect, sparse or individual,
thin setae; erect setation of antennae heterogeneous, almost same
as in other representatives of the genus: male antennomeres1–7,
except for basal part of antennomeres4 and5, on inner and, partly,
venral sides, in female, at least antennomeres 1–6 also on inner
and, partly, venral sides with numerous, short, erect, somewhat
oblique, thin setae in the form of sparse gentle brush (infemale,
these setae badly damaged, at least they look much less clearly than
in male), thereby both in male and female, antennomeres2–10 at
apex with individual, long, thin setae directed towards apex of
antennae and individual, long, erect setae in apical part ventrally;
peculiar area in basal part of male antennomeres 4 and 5 with
sparse erect setae, as Figs136,143.

selflessly supports my entomological research and provides
an invaluable editing assistance in preparing very numerous

Diagnosis. is new species is most similar to
E. tatianae sp. n., but differs clearly by the peculiar
sculpture of the pronotum, in particular, the structure of
two symmetrical longitudinal elevations in the middle
part of the disc, each of which is devoid of a very sharp
protrusion on the external side in front of the middle, as in
Figs181,182, the partly less saturated, yellow and golden-
yellow coloration of the dorsum, the structure of the
antennae of the male, in particular, the peculiar sculpture
of the area at the base of antennomeres 4 and 5, as in
Figs137,144, the distinctly inflated antennomere4, the last
(visible) sternite of the male devoid of a clear emargination
apically, the last (visible) sternite of the female truncate
apically (not rounded), and some other minor traits
(cf.Figs136, 143,180).

37: 36 : 34 :47 in male and female, respectively; antennomere 1
with a heterogeneous, partly rough, rugose, dense puncturation,
more strongly expressed in male, on inner side in about apical
one-third somewhat narrowed towards apex, but less clearly than
at least in male of E. tatianaesp. n.; antennomere 2 distinctly
transverse; antennomeres3 and 4 of male moderately inflated in
apical part, thereby base of antennomere4 barely wider than that
of3rd; antennomeres4 and5 each with a peculiar area at base, this
being characteristic of the genus and showing a relatively coarse
sculpture and well-visible numerous pores, as in Figs137,144.
Pronotum of male subequal in length and width, in female
slightly longitudinal, at base barely or slightly wider than at apex;
with a very sharp constriction near apex; on disc with longitudinal,
very coarse, sinuous folds and two longitudinal, wide, coarsest
and highest near middle, symmetrical elevations in middle part
(Figs181,182), each of which on external side can be angularly
broadened from both base and apex towards about middle, as in
Fig.182, thereby elevations with a small dense puncturation and
individual or numerous coarse punctures.
Scutellum strongly narrowed towards apex, triangular.
e longicorn beetle tribe Cerambycini Latreille, 1802 (Coleoptera: Cerambycidae: Cerambycinae) 189
Elytra about parallel-sided, 2.68–2.74 times as long as
humeral width; with a very small dense puncturation; apical
external angle about obtuse, well-expressed, sutural angle with a
small denticle, thereby both angles masked under a dense setation.
Prosternum with a clear, but not too sharp transverse groove
in front of middle, with heterogeneous, coarse or rough, transverse
and transversely oblique, partly irregular folds; prosternal process
with a very strong apical tubercle; mesosternal process without
tubercle dorsally, between coxae clearly wider than prosternal
process; mesosternum partly, metasternum and sternites with a
small dense puncturation; metasternum with a clear, not sharp
median groove; last (visible) sternite at apex truncate both in male
and female; last (visible) tergite at apex in male with a small, but
distinct emargination, in female truncate.
Legs moderately long; protibia very clearly broadened from
base towards apex; metatibia at anterior margin clearly concave,
this characteristic of the genus, as in Figs 167, 168; tarsomere1
very clearly shorter than tarsomeres2 and3 combined.
Recumbent setation similar to that of other species of the genus,
on head dorsally, pronotum, partly elytra, antennae and legs mainly
yellow and yellowish tones, partly with golden and silvery tints,
on venter greyish; more or less dense setae covering most of head
dorasally, partly basal antennomeres, tibiae, metafemora, tarsi, on

more or less long, erect, partly suberect, sparse or individual, thin
setae; erect setation of antennae heterogeneous, almost same as in
other representatives of the genus: male antennomeres1–6, except
for basal part of antennomeres4 and5, on both inner and ventral
sides and, besides this, all subsequent antennomeres predominantly
on inner side, while female antennomeres1–3 on inner side and
almost over entire ventral one and, besides this, antennomeres4–7
predominantly on inner side with numerous, short, erect, somewhat
oblique, thin setae in the form of sparse gentle brush, thereby both
in male and female, antennomeres1–10 at apex with individual,
long, thin setae directed towards apex of antennae and individual,
long, erect setae in apical part ventrally.

to my colleague, Dr. Francesco Vitali (Musée national
d’histoire naturelle de Luxembourg), who kindly provided
a very valuable material for study and shared his important
scientific information.

Genus Spinidymasius Miroshnikov, gen. n.
Type species: Imbrius strigosus Pascoe, 1866 =
Dymasius (Elydnus) pascoei Gahan, 1891.
Diagnosis. e new genus is very similar to Dymasius
J.omson, 1864, but differs by the structure of the apex
of antennomeres 6–10, namely, the inner angle with a
more or less developed, sharp spine, as well as by the last
antennomere being either sharpened or strongly sharpened,
or drawn into a sharp spine apically, thereby both features
usually/more often being expressed to the strongest degree
in the female, as in Figs212–216.
Besides this, Spinidymasiusgen. n. is characterized
by the following features, the combination of which makes
it even more distinct compared to the other genera of
the tribe, including Dymasius: head with moderately
developed eyes; antennae of male very long or shorter,
extending beyond apex of elytra at least by antennomere9,
in female one way or another, but always longer than
body, antennomere 1 with a variable sculpture, with or
without cicatrix, sometimes with a very strong external
lateral process (protrusion), antennomeres6–10 clearly or
strongly broadened at apex on external side and there can
be with a strongly sharpened or spiny angle, antennomere4
subequal to or slightly shorter than 5th, antennomere 2
clearly or strongly transverse, antennomere3 one way or
another longer than or subequal to, but not shorter than5th,

last antennomere can be extremely long, exceeding the
length of previous antennomere up to 4times; pronotum
to some degree variable in shape, from clearly longitudinal
to subequal in length and width or slightly transverse,
broadly rounded on either side, on disc with coarse or
very coarse, predominantly or only transverse folds, but
sometimes can be with predominantly irregular folds;
setation of pronotum of dense, recumbent, light setae can
form predominantly or only longitudinal strips, but in any
case lack a clear pattern of separate, differently shaped,
symmetrical spots; elytra moderately elongated, with a
heterogeneous, mostly more or less small, irregular, in
places dense (but not confluent) puncturation, each elytron
at apex either obliquely or straightly truncate, or slightly
emarginate, sutural angle with a more or less strongly
developed denticle, but without a very long tooth, external
angle very well-expressed, never rounded or very strongly
obtuse, sometimes drawn into a very long sharp tooth;
setation of elytra of dense, recumbent, light setae forms
more or less distinct longitudinal strips or a continuous
(subcontinuous), but always patterned, contrasting,
iridescent surface, never a uniformly continuous setation;
prosternum with a clearly-expressed, deep, relatively wide,
transverse groove in front of middle, as a rule; prosternal
process with a sharp, very sharp or at least well-expressed
tubercle; mesosternum with a clear or sharp/very sharp
tubercle or without such; legs robust, moderately long,
femora more or less claviform; metatibia comparatively
straight (at least never clearly nor visibly concave on
external side); femora and tibiae without longitudinal
carina; tarsomere1 clearly shorter than tarsomeres2 and3
combined; body from medium- to large-sized, in length
19.4–33mm.
It seems very remarkable that another new genus,
Falsopachydissus gen. n., also described here, is
characterized by the structure of antennomeres 6–10
similar to that in Spinidymasiusgen.n., but these genera
differ very clearly from each other by the features shown
below in the diagnosis of the former.
Remarks. Allotting a generic status to
Spinidymasius gen. n. at this stage of research, despite
its generally very close resemblance to Dymasius, is not
only because the former after all seems to represent a
morphologically quite clearly delineated group of species,
but also based on some other considerations.
As already mentioned several times by individual
researchers, including a few very recently [Holzschuh,
2015; Miroshnikov, 2016, 2017], the genus Dymasius,
whose numerous representatives show great morphological
diversity, is highly heterogeneous and needs a detailed
revision. e previously proposed intrageneric structure
of Dymasius with three subgenera [Gressitt, Rondon,
1970] is now obsolete, since Microdymasius Pic, 1946 is
considered as a separate genus [Holzschuh, 2015], while the
taxonomic status of Elydnus and its species composition
are substantiated in the present paper. Under these
circumstances, the establishment of Spinidymasiusgen.n.
as a subgenus of Dymasius would hardly be justified, since
the formal inclusion of all other species in the subgenus
Dymasiuss. str. would be taxonomically erroneous. e
clarification of the status of Spinidymasiusgen.n. seems
to be possible, in my opinion, only within the framework of
a detailed revision of Dymasius and the development of its
reasonable intrageneric classification.
Etymology. e formation of the name of this new
genus is related to its greatest similarity to the genus
Dymasius and the most important diagnostic feature in the
structure of the antennae.
Composition. e genus includes nine species.

Comparative material. 1♀ (see Remarks below) (BMNH) (Fig.190),

sericatus (Pascoe, 1869) (?sp.n.) ♀ det.A.Miroshnikov 2017”.
Remarks. I have studied the holotype of this species
which is a female (Fig.189), plus another female (Figs190,
202, 205, 207, 209, 213, 450) with the labels “Sarawak”,
“Elydnus sericatus Pasc., comp. with type”. Both are very
similar and kept in BMNH. e holotype of S.sericatus
comb. n. differs from the Sarawak female by the structure
of the apical part of the prosternal process, including
the shape and location of the apical tubercle, as in Figs
206,207, the clearly more strongly developed, recumbent,
light setation on the head dorsally and on the pronotum
(see Note below), the somewhat coarser, at least partly so,
sculpture of the pronotal disc (Figs201, 202), the denser
recumbent light setation of the prosternum (Figs204,205),
and the slightly wider scutellum. It must thereby be
noted that the setation on the head dorsally and on the
pronotum, the sculpture of the disc of the pronotum, as
well as the structure of the apical part of the prosternal
process of the holotype of S. sericatuscomb. n. are all
very similar to those of the holotype male of S.tawauanus
(Vives et Heffern, 2016), comb. n. (information on the
structure of the prosternum of the latter species was
kindly provided by Mr.DanielJ.Heffern, Houston, USA,
in whose collection it is kept; his personal communication
of July11,2017).
Taking into account the above, if one assumes that
the female from “Sarawak” represents a yet undescribed
species, then S. tawauanuscomb.n. is most likely to be
a senior synonym of S. sericatuscomb. n. However, this
issue can only be solved when additional material becomes
available for study. In this connection, one must also
be aware that the type locality of S. sericatuscomb. n.
(holotype) as indicated both on its label and in the original
description might appear to be erroneous.
e body length is 27.5 or 27.2mm and the humeral
width is 6.8 or 6.5mm in the holotype and the female from
“Sarawak”, respectively.

Note. In the female from “Sarawak”, the setation
of the pronotum seems to be abraded in places, but it is
very well preserved at least at the base and apex of its disc,
as well as on the head, including behind the eyes, and it
looks clearly sparser in comparison with the holotypes of
S.sericatuscomb.n. and S.tawauanuscomb.n.
Distribution. Banda Islands (Indonesia, Maluku)

holotype); ?Eastern Malaysia (see Remarks above).

(Pseudaeolesthes) chrysophanes Gressitt & Rondon det. 196[?]” (Fig.448).
Morphological notes. Holotype female. Body length
26.2mm, humeral width 6.9mm.
Remarks. Most recently, Vitali et al. [2017: 58]
transferred this species to the genus Elydnus, thereby they
noting the following: “is species is characterised by
mutic antennae and interantennal furrow. e pronotum
shows a single median furrow, while the elytral pubescence
is longitudinally striped and obscured along the suture. All
these characters belong to Elydnus Pascoe, 1869; actually,
this species is extremely similar to the type-species
E.amictus Pascoe 1869.”
In my opinion, however, the holotype female of
Spinidymasius chrysophanescomb. n. I have revised
is very similar to the holotype of S. sericatuscomb. n.
and differs mainly by the structure of the pronotum, in
particular, its slightly transverse shape and predominantly
irregular folds on the disc, as in Fig.203 (inthe holotype of
S.sericatuscomb.n., the pronotum is subequal in length
and width, and the disc is mostly with transverse folds, as
in Fig.201), whereas it is likewise distinguished very clearly
from Elydnus amictus by the features of antennal structure
characteristic of Spinidymasiusgen.n., namely, the presence
of a spine at the apical inner angle of antennomeres6–10,
the last antennomere sharpened apically (Fig.214), as well
as by the generally noticeably different antennae, including
the shape and pattern of setation of antennomeres, the
metatibiae straight (not concave) at the anterior margin
(Fig. 210), both the shape and setation of the elytra and
protibia, and some other traits.
Notes on the type locality. Vitali et al. [2017] have
corrected the type locality of S. chrysophanescomb. n.
which was confused in its original description [Gressitt,
Rondon, 1970], proposing the following: Cambodia, Koh
Rong Sanloem Island, Saracen Bay. is quotation is indeed
unquestioned.
At the same time, through the kind assistance of
Dr. GérardL. Tavakilian (MNHN), I seem to have been
able to completely decipher the geographical label of the
holotype (see both Material and Fig. 448), from which it
follows that the beetle had been collected at light near
the lighthouse on the island (islands) within the Saracen
Bay. Eventually, this bay has only a single island, namely,
Koh Rong Sanloem Island (exactly as given by Vitali et
al. [2017]). As far as is known, however, there is a single
lighthouse on the island, located in its extreme south. Now
this lighthouse is an abandoned building. So it is obvious
that this place is to be considered as the strict type locality
of S.chrysophanescomb.n.
Considering the above, the type locality of this
species is refined as follows: Southwestern Cambodia, Koh
Rong Sanloem Island (Saracen Bay), near the lighthouse
(10°32’42N”/ 103°19’04”E).
Distribution. Cambodia.

Catalogue..., 2010: 160; Heffern, 2013: 9.
Type species: Dymasius strigosus J. omson, 1864,
by monotypy (?=Cerambyx macilentus Pascoe, 1859; see
Remarks to this species below).
Remarks. is genus is widely distributed and
covers South, East and Southeast Asia. is is a clearly
heterogeneous group of species rather diverse in
composition, which requires a very detailed revision.
Taking into account the new forms described here
and some remarks, Dymasius counts more than 50species.
Besides this, at least several species, yet undescribed, but
known to me and, partly, in one way or another mentioned
in this paper, show that a noticeable replenishment of the
composition of the genus can also be expected in the future.
Descriptions of two new species are given below, the
synonymy of the type species of the genus, D.strigosus, and
D.macilentus (Pascoe, 1859) is discussed, as well as some
comments concerning D.minor Gahan, 1906 are presented.
Dymasius makarovi Miroshnikov, sp. n.
(Figs 217, 219, 221, 225–227, Color plate 3: 250, 252, 254)
Material. Holotype, ♂ (cAM) (Color plate 3: 250): W Malaysia,
Pahang, Cameron Highlands, Tanah Rata, 04.2015 (local collector).
Paratypes: 1♂, 1♀ (Color plate 3:252) (cAM), same label as holotype.
Diagnosis. is new species is very similar to
D.cuneatulus Holzschuh, 2005, but differs by the pronotum
being relatively narrower at the apex, as in Figs 217, 219
(cf. Figs 218, 220), the somewhat peculiar sculpture of
its disc, as in Figs 217, 219 (cf. Figs 218, 220), against the
background of a rough elytral puncturation similar to that
of D.cuneatulus, with sharper and very small punctures on
the elytra, as in Fig.221 (cf.Fig.222); in the narrower apical
tubercle of the prosternal process; the general coloration
of the recumbent setation, as in Color plate 3: 250, 252
(cf.Color plate 3:251, 253); by some features of the male, in
particular, the longer antennae, the less strongly elongated
apical antennomeres, especially the last one, as in Color plate
3:250 (cf.Color plate 3:251), antennomeres3–5 distinctly
less strongly inflated in their apical parts, as in Color plate
3:250 (cf.Color plate 3:251), antennomere1 narrower near
the base, the less sharp antennal tubercles, the less strongly
developed setation of the submentum, as in Color plate 3:254
(cf.Color plate3:255), the somewhat peculiar structure of
the apical part of the tegmen, including the parameres, and
of the penis, as in Figs225,226 (cf.Figs228,229), the lighter
tergite8, as in Fig.227 (cf.Fig.230).
Remarks. Very recently, Vitali et al. [2017] quite
correctly transferred Aeolesthes fulgens Schwarzer, 1926
(Philippines, Mindanao, Surigao) to the genus Dymasius.
ey thereby noted the following: “Actually, Dymasius
fulgens (Schwarzer, 1926)n.comb. is closely related to the
Bornean D.cuneatulus Holszchuh 2005, which might be a
subspecies or even a synonym of the Philippine species.”
[Vitali et al., 2017: 53].
rough the courtesy of Dr. Andre Skale (Hof,
Germany), Ihave received a good picture of the holotype
male of this species, although such is also available in Vitali
et al. [2017].
Based on this picture, D. fulgens, albeit very similar to
D. cuneatulus, differs (there are 2males, 6 females and a
quality photograph of the holotype male of D.cuneatulus
at my disposal) at least by the elytra being generally wider,
especially so in the apical part, thereby somewhat less
strongly narrowed towards the apex, by their apical external
angle drawn into a sharp tooth directed about straight
downwards, seemingly the coloration of the elytra, as well
as by the clearly more strongly elongated antennomere1.
In my opinion, D. cuneatulus is almost without any
doubt a “good”, separate species.
Dymasius makarovisp.n. differs from D.fulgens by the
same features as D.cuneatulus from the latter, as well as by
the shorter antennae of the male, the less strongly elongated
apical antennomeres in addition to antennomere1, and the
pronotum relatively narrower at the apex.
Description. Body length 27.5–32.8 mm, humeral width
6.9–8.3mm, thereby holotype 29.2 and 6.9mm, respectively. Head
dorsally, pronotum, antennae, legs, partly venter black; elytra,
partly venter, sometimes most of legs and venter reddish brown
and dark reddish brown, thereby elytra of female black-brown with
a reddish tint.

(Color plate 3: 256)
Material. Holotype, ♀ (cSM) (Color plate 3:256), Sri Lanka, Kitugala,
600m, 6°59’N/ 80°24’E, 30.01.1999 (leg.S.Murzin).
Diagnosis. is new species seems to have no clear
resemblance to any species of the genus Dymasius. By
the presence and arrangement of longitudinal strips of
dense recumbent setae on the pronotum and elytra,
combined with the structure of the antennae, the
black monochrome coloration of the integument of
the dorsum, and the monochrome legs it somewhat
resembles D.lepidus Holzcshuh, 2005, but differs easily
at least by the peculiar sculpture of the pronotum and
elytra, the bright yellow coloration of the strips on the
elytra, and the structure of the elytral apex, as in Color
plate 3:256.
Description. Female. Body length 15.4mm, humeral width
3.1 mm. Coloration of integument mainly combines red-brown
and dark reddish-brown tones, thereby most of elytra darkest; eyes
and partly pronotum black.
Head with clear, but not too strong antennal tubercles;
sculpture of dorsum hidden by a very dense setation; eyes very
well-developed, relatively strongly convex, with pretty large ocelli;
genae short; submentum with an obliterated sculpture; neck
almost entirely with more or less sharp transverse folds ventrally;
antennae reaching beyond apex of elytra by last antennomere,
thereby clearly not reaching the base of elytra by antennomere4;
length ratio of antennomeres1–11, 27 : 6: 33 : 21 : 34 : 35:
34: 30: 31: 28: 36; antennomere 1 without coarse sculpture,
including cicatrix (apical carina); antennomere 2 subequal in
length and width; antennomeres 7–10 distinctly serrate; last
antennomere with a clear appendage, rounded apically.
Pronotum strongly longitudinal, 1.3times as long as width;
base 1.14 times as wide as apex; with a clear constriction near
apex; slightly convex; on disc with rough irregular folds, as in Color
plate3:256.
Scutellum strongly narrowed towards apex, triangular.
Elytra strongly elongated, predominantly about parallel-
sided starting from base, 3.1times as long as humeral width; with a
weak sparse puncturation; apical external angle drawn into a large
tooth, sutural angle with a clear denticle, as in Color plate 3:256.
Prosternum in apical half with a rough irregular
sculpture; prosternal process without distinct apical tubercle;
mesosternal process without tubercle dorsally, between coxae
clearly wider than prosternal process; mesosternum partly,
metasternum and sternites with a distinct relatively dense
puncturation; metasternum with a clear, not sharp median
groove; both last (visible) sternite and tergite widely rounded
apically.
Legs moderately short; femora distinctly claviform, with
a longitudinal carina on sides; tarsomere 1 clearly shorter than
tarsomeres2 and3 combined.
Recumbent dense setation ocher-yellow, on pronotum and
elytra forming longitudinal stripes, as in Color plate 3: 256, on
head dorsally very dense, on venter the densest on sides of pro-,
meso- and metasterna and over most of sternites; head, pronotum
laterally, abdomen at apex, legs on trochanters with more or less
long, erect, partly suberect, sparse or individual, thin setae.
Etymology. I am pleased to dedicate this new species
to my colleague and friend, Dr.SergeyV.Murzin (Moscow,
Russia), who collected the holotype and, over the many
years, supports my entomological research.

Dymasius macilentus (Pascoe, 1859)
(Figs 198, 223, 233–235, 451)
Cerambyx macilentus Pascoe, 1859: 20. Type locality: Ceylon
(now Sri Lanka) (according to the original description and the label
of the holotype).
Dymasius macilentus: Gahan, 1891: 22; 1906: 139; Makihara
et al., 2008: 100, pl.1, fig. 9 (wrong determination; see Remarks
below); Kariyanna et al., 2017: 29.
Dymasius (Dymasius) macilentus: Aurivillius, 1912: 60.
Material. ♂, holotype, by monotypy (BMNH) (Fig. 198), “Ceylon”
(upperside), “59.106” (underside), “Cerambyx macilentus Pascoe, Type”,
”Type” (Fig.451).
Remarks. is species is known to me only from the
holotype Ihave revised, with a body length of 28.2mm and
a humeral width of6.8mm.
Until now, D.strigosus J. omson, 1864 (Figs 199,
224, 452) has traditionally been believed to represent a
junior synonym of D. macilentus (including in the most
recent publications, in particular, Kariyanna et al. [2017]),
the synonymy first advanced by Gahan [1906] and followed
by Aurivillius [1912].
However, when comparing the male holotypes of
these taxa, I drew attention to some significant differences
they showed, primarily in the structure of the antennae.
us, in the holotype of D. macilentus, antennomere3 is
only 1.36 or 1.32times as long as antennomeres1 and 4,
respectively, antennomere 5, 1.32 times as long as 4th,
antennomere 1 with a dense, skin-deep, partly slightly
rugulose puncturation, while the holotype of D. strigosus
has antennomere3 about 1.6 or almost 1.5times as long as
antennomeres1 and4, respectively, antennomere5 about
1.6 times as long as 4th, and antennomere 1 seems to be
mainly coarsely to very coarsely sculptured (Figs223,224).
Besides this, in the former species, the antennae are clearly
shorter, thereby the last antennomere both by itself and
in relation to the length of the pronotum is considerably
shorter (Figs198, 199), antennomeres3–5 are somewhat
more strongly inflated in the apical parts (Figs 198, 199,
223, 224). In the holotype of D.macilentus, the pronotum
is clearly more strongly elongated, 1.31 times as long as
wide at the base, while in the holotype of D.strigosus the
pronotum is only 1.17 times as long as wide at the base
(Figs223,224). In the former species, the apical external
angle of the elytra is produced into a very strong tooth
more strongly drawn towards the external side, while in the
latter species this tooth is about half as long, thereby the
restudied holotypes generally differ clearly in the shape of
the elytral apex (Figs198,199).
It is quite possible to admit that the shape of the
pronotum (more or less elongated) and the teeth at the
apex of the elytra can be variable, but to also regard the
very significant differences in the length ratios of the basal
antennomeres, as well as in the sculpture of antennomere1
as individual variability seems to be rather difficult. Ihave not
been able yet to study any other material, but nevertheless
it is quite obvious that the synonymy D. macilentus =
D.strigosus demands indisputable evidence.
Certain records of D. macilentus likewise require
clarification. In particular, the male from Sri Lanka
(Sigiriya, Matale Distr.) depicted in the paper of Makihara
et al. [2008: pl. 1, fig. 9] is similar, in my opinion, to
neither the holotype of D.macilentus nor the holotype of
D.strigosus. is specimen generally looks like one of the
representatives of the genus Dialeges Pascoe, 1857.

Morphological notes. Body length 9.4 or 10.9 mm,
humeral width 2 or 2.2 mm in the lectotype and
paralectotype, respectively.
Remarks. is species was described from two males,
these two probably remaining its only material known to
date. In the present paper, D.plagiatus is illustrated for the
first time.
e female from Sri Lanka (Sigiriya, Matale Distr.),
depicted in the work of Makihara et al. [2008: pl. 2,

undescribed species.
Genus Zegriades Pascoe, 1869
Zegriades Pascoe, 1869: 525. Gemminger, 1872: 2805;
Aurivillius, 1912: 62; Heffern, 2013: 12.
Type species: Xoanodera magister Pascoe, 1857, by
monotypy.
Diagnosis. Representatives of this genus seem to
resemble most closely some species of the genus Dymasius,
in particular, through having, to varying degrees, a long
antennomere3, especially in the male, and the antennae,
also in the male, generally much longer than the body, but
differ by the following features. Zegriades is characterized
by the comparatively longest antennomere3 of the male,
which is 2.21–2.5times as long as antennomere1, thereby
the latter is with a sharply expressed cicatrix (including
the female) (Color plate 4:257–262), whereas in Dymasius
(in particular, in such species as D.mandibularis (Gahan,
1891), D.cos Holzschuh, 1998, D.fedorenkoi Miroshnikov,
2016), antennomere 3 of the male is not more than
1.93 times as long as antennomere 1 (see also below),
thereby the latter is devoid of a cicatrix (including the
female); generally speaking, a cicatrix in Dymasius is
observed extremely rarely and it seems to be present only
in D.brevipes Holzschuh, 1991, but antennomere3 of the
male of this latter species is only moderately long and it
is not similar to representatives of Zegriades by many
other characters; in my opinion, the generic attribution
of D. querceus Holzschuh, 2015 (Fig. 405), with both a
long antennomere3 and, based on the picture, a cicatrix
on antennomere 1, requires clarification, also bearing in
mind that this species is most likely to belong to the genus
Pachydissus Newman, 1838.
e longicorn beetle tribe Cerambycini Latreille, 1802 (Coleoptera: Cerambycidae: Cerambycinae) 203
In Zegriades, tergite8 of the male is with a very deep
emargination apically, as a result of which the apex proper
looks bidentate (Figs248,249), while in Dymasius, tergite8
of the male has no emargination, as a rule (Figs227, 230,
235,240); if,however, certain Dymasiusspp. do sufficiently
strongly resemble Zegriades spp. in the structure of this
tergite (Fig.243), then by many other features they differ
significantly from the latter genus; such is, for example,
D. indigus Holzschuh, 2008, in which, in comparison
with Zegriades, the structure of the head, the shape of
the pronotum, the character of the dorsum, the structure
of the prosternum, penis and tegmen (Figs 241, 242) are
different in addition to its antennomere3 of the male being
only 1.6 times as long as the 1st (by the way, this species
was described from two females and elsewhere, in one of
my following papers, I plan to give the first description
of its male Ihave got at my disposal); generally speaking,
an emargination at the apex of male tergite8 that exists
in this or that genus of the tribe, for example, in Elydnus,
Zatrephus Pascoe, 1857 (Figs155–158, 287–290), is never
very deep and the apex proper of the tergite does not look
bidentate.
e genus Zegriades is also characterized by the
following features, the combination of which makes it even
more distinct compared to Dymasius and at least the other
similar genera of the tribe: head with long (male) or shorter
(female), widely rounded temples and a well-expressed
constriction behind them, clearly delimiting a neck, as in
Figs231, 232, Color plate 4: 261, 262; eyes slightly convex;
antennae generally slender, as in Color plate 4:257–260, in
male more than 2times as long as body, in female extending
beyond apex of elytra by penultimate antennomere,
antennomere 2 subequal in length and width, but not
transverse, antennomeres 3–5 in apical parts distinctly
inflated (toa greater extent in male than in female), apical
external angle of antennomeres8–10 can be with a small,
but evident and sharp spine, most of male antennomeres to
a varying degree strongly elongated; pronotum very clearly
or strongly longitudinal, widely rounded on sides, as in
Color plate 4:261,262, its disc weakly convex, with more or
less sharp transverse folds; setation of pronotum of dense,
recumbent, yellow or yellowish setae forms longitudinal
strips, leaving middle part of disc almost bare through
a broad stripe, as in Color plate 4:261,262; elytra in male
slightly narrowed towards apex, in female in front of middle
can be slightly broadened, apical external angle clearly-
expressed, sutural angle drawn into a long or shorter tooth,
with a heterogeneous, in places irregular, partly rugulose
puncturation; setation of elytra of dense, recumbent, yellow
or yellowish setae forms clear longitudinal strips, either
entire or partly broken by strokes and partially confused, as in
Color plate 4: 257–260; prosternum without clear transverse
groove in front of middle, only with coarse transverse folds,
prosternal process dorsally relatively strongly broadened in
apical part, as in Figs 231, 232; mesosternum with a more
or less distinct (but not sharp) tubercle; legs slender, rather
long, femora not claviform; metatibiae straight; femora and
tibiae without longitudinal carinae; tarsomere 1 clearly
shorter than tarsomeres 2 and 3 combined; penis rather
broadly rounded apically, as in Figs244, 245, tegmen as
Figs246,247; body from medium- to large-sized, in length
20.1–34.3mm, but obviously up to 40mm (see below).
Remarks. To somewhat detail the significance of the
length ratios of antennomeres 1 and 3 of the male
in the genera compared, in Dymasius mandibularis it
is1.8–1.92, in D.cos about the same as the highest value
in the previous species, in D. fedorenkoi it is1.89 (besides
this, these species differ very clearly from Zegriadesspp. by
the shape of the apical part of both penis and tegmen, as in
Figs236–239, 244–247, and by a number of other features).
At the same time, Ihave at my disposal a photograph of
a male representing a not yet described Dymasius species
from India, in which, based on the picture, antennomere3
is about twice as long as the1st, but in this case, as usual,
antennomere1 is devoid of a cicatrix, while many other
morphological features of the beetle, including the structure
of the head, the setation of the dorsum, the shape of the
elytra apex, are all different from Zegriades. e females
of the genera compared fail to differ in the length ratios of
antennomeres1 and 3. us, in the female of Z.magister
(Pascoe, 1857) this ratio is 1.76–1.77, but it reaches the
same values in the female of D.mandibularis; in the female
of D.cos, based by the picture Ihave, this value is slightly
lower than the previous ones; no female D. fedorenkoi is
known yet.
It is noteworthy that some species previously
described or considered in the genus Zegriades [Gressitt,
1939, 1951; Gressitt, Rondon, 1970; Catalogue..., 2010]
have been transferred to other genera only relatively
recently, in particular, Gibbocerambyx Pic, 1923
[Holzschuh, 2003, 2010], Dymasius [Holzschuh, 2010]
and Imbrius [Holzschuh, 2005]. At the same time, the
systematic position of one species transferred to the latter
genus is also clarifed in the present paper (see above genus
Mimimbriusgen.n.).
Besides this, the long described Zegriades siamensis
and Z. fulvipennis [Nonfried, 1895] are known to me
only by their original descriptions, albeit I have repeated
attempted to relocate the types in a number of European
museums and some other institutions. No information
on the whereabouts of the types is likewise available
from the literature, nor can anyone among my numerous
colleagues could help me in this respect (their personal
communications). Based on the original descriptions alone,
both species, almost without any doubt, do not belong to
Zegriades, at least so in accordance with a number of those
morphological characteristics of the genus that are given
above (the diagnosis of Zegriades omits those or other
features noted in Nonfried’s descriptions). At the same
time, I formally include Z.siamensis and Z.fulvipennis in
the present review, as well as in the key (based on some
features taken from the descriptions), since I have no
indisputable evidence for their incorporation into any
other genus or genera.
us, the genus Zegriades includes four species, one of
which is described as new, while two species are considered
here solely conditionally.

on the material studied, Z. magister is being recorded
here from ailand, and generally from Indochina, for
the first time. However, the label data (“...Siam”, Fig.455)

Zegriades olemehli Miroshnikov, sp. n.
(Figs 231, 244, 246, 248; Color plate 4: 257, 261)
Material. Holotype, ♂ (NHMD) (Color plate 4: 257): E Malaysia,
Sabah, Trus MadiMt., 04.2014 (local collector).
Diagnosis. is new species is similar to Z.magister,
but differs by the longer antennomere 3, at least so in
the male, which is 2.5 times as long as antennomere 1
(in Z. magister, male antennomere 3, 2.21–2.38 times as
long as antennomere1), the continuous and non-confused
longitudinal strips of dense, recumbent, yellow setae on
the elytra (Color plate 4:257), the slightly more elongated
pronotum (Color plate 4:261), the more fragmentary (less
entire) and partly less sharp transverse folds of its disc, the
apical sutural angle of the elytra with a shorter tooth hidden
by dense setae, the more strongly developed, recumbent,
light setation of the head dorsally behind the eyes that form
no distinct longitudinal strips (Color plate 4:261), and the
smaller body sizes (cf.Color plate 4:258–260, 262).
Description. Male. Body length 20.1 mm, humeral width
4.35 mm. Dorsum, partly antennae black; venter, legs, most of
antennae reddish brown and dark reddish brown tones.
Head with well-developed antennal tubercles; with a sharp
median groove between bases of antennae, eyes and partly on
vertex; eyes slightly convex, their upper lobes strongly connivent;
genae long, longitudinal diameter of lower lobe of eye not more
than 1.4 times as long as genae; temples very long, only slightly
shorter than longitudinal diameter of lower lobe of eye, widely
rounded, noticeably narrowed backwards, with rough transverse
folds; behind temples with a sharp constriction clearly separating a
neck; gula with transverse small folds; ne ck with transverse oblique
small folds; submentum moderately transverse, only twice as wide
as long, somewhat impressed, with unclear sculpture; antennae
slender, very long, about 2.4 times as long as body, thereby
reaching the apex of elytra by apex of antennomere6; length ratio
of antennomeres1–11, 21:7: 52: 27: 37: 59: 54: 50: 49: 51:104;
antennomere1 with a strong cicatrix (apical carina), along almost
entire length clearly and broadly impressed dorsally, partly with
a rough rugose puncturation; antennomere2 subequal in length
and width; antennomeres 3–5 distinctly inflated at apex, as in
Color plate 4: 257; apical external angle of antennomeres 8–10
with a small, but clear, sharp spine (in Z.magister, small sharp
spine can only be on antennomere8 while apical external angle
of antennomere9 without spine, can be not more than sharpened,
at least in specimens revised; see above); last antennomere with a
distinct appendage.
Pronotum strongly longitudinal, 1.3times as long as width;
base 1.23 times as wide as apex; with a sharp constriction near
apex; on disc slightly convex, with transverse, partly oblique,
coarse, pretty regular folds, as in Color plate 4:261.
Scutellum strongly narrowed towards apex, triangular.
Elytra strongly elongated, weakly narrowed towards apex,
3.12times as long as humeral width; with a dense, partly rugose,
relatively rough puncturation between longitudinal stripes of dense
setae, and a very small and dense, finely scabrous puncturation
under these stripes; apical external angle obtuse, sutural angle
drawn into a clear, but small denticle hidden by a dense setation.
Most of prosternum with transverse and transversely oblique
folds, the coarsest in middle part; prosternal process strongly
broadened towards apex dorsally, with a strong tubercle at apex;
mesosternal process without tubercle dorsally, between coxae
distinctly wider than prosternal process; mesosternum partly,
metasternum and sternites with a small dense puncturation;
metasternum with a clear, not too deep median groove; last
(visible) sternite truncate apically; last (visible) tergite at apex with
a barely visible emargination.
Legs pretty long; tarsomere1 clearly shorter than tarsomeres2
and3 combined.
Recumbent dense setation of dorsum, several basal
antennomeres dorsally, legs predominantly on inner side, partly head
ventrally yellow tones, thereby on both pronotum and elytra forming
longitudinal stripes, as in Color plate 4: 257; setation of venter,
external side of legs and partly antennae ventrally mainly greyish and
greyish yellowish tones; head, pronotum on sides in apical part , apex
of abdomen, most of antennomeres in apical part with more or less
long, erect, partly suberect, sparse or individual, thin setae.
Genitalia as in Figs244, 246, 248.
Etymology. is new species is dedicated to the
memory of Ole Mehl (1948–2015), a remarkable Danish
coleopterologist and connoisseur of longicorn beetles, who
collected a rich and very valuable collection of this family,
especially from the Oriental Region, now kept in NHMD.
e study of a diverse material from this collection has
made it possible to solve in one way or another various
questions of the systematics of some groups, including the
discovery of new taxa.
Distribution. Eastern Malaysia.

Genus Zatrephus Pascoe, 1857
Zatrephus Pascoe, 1857: 94. omson, 1864: 235; Pascoe,
1869: 523; Lacordaire, 1868: 267; Gemminger, 1872: 2805;
Aurivillius, 1912: 62; Gressitt, Rondon, 1970: 88; Catalogue...,
2010: 162; Heffern, 2013: 12.
Type species: Zatrephus pannosus Pascoe, 1857, by
subsequent designation [Gressitt, Rondon, 1970].
Diagnosis. is genus is primarily characterized by
the robust, medium- to large-sized body, 18.3–37mm in
length, the setation of the elytra being at least two-coloured,
one way or another spotty, often rather variegated, without
silky lustre, almost continuous or occupying most of the
surface, as in Figs 263–274, in one degree or another
similar to the elytral setation of at least the abdomen and
metasternum (Fig.345) and, besides this, often of the legs
and antennae, antennomeres 3–5 being relatively short,
strongly, very strongly or clearly inflated in the male and
distinctly inflated in the female, as in Figs363–368, the
absence from all antennomeres of any clearly expressed
sculptural formations, including spines, from the slightly
transverse to the slightly longitudinal pronotum with
variable sculpture, as in Figs275–386, but at least forming
no long longitudinal folds. By these features combined,
Zatrephus differs clearly from all other genera of the tribe,
including similar ones.
By the character of elytra setation, the structure of
the pronotum and other individual features, Zatrephus
can be compared to the genus Rhytidodera White, 1853,
at least with some of its representatives, but differs
either in the shape of antennomeres 3–5, especially of
the male, or in the structure of almost all antennomeres
(inRhytidodera, antennomeres3–5 can be neither clearly
nor strongly inflated, while, in contrast to Zatrephus, many
antennomeres can be strongly serrate), the very sharply
or clearly expressed tubercle on the prosternal process
(in Rhytidodera, a tubercle on the prosternal process is
absent or can only be weakly developed), the polychrome
setation of at least the abdomen and metasternum, like
that on the elytra (in Rhytidodera, the abdomen and
metasternum, often also the remaining part of the venter
monochrome light).
Important structural details of Zatrephus are
also listed below, in the diagnosis of the new genus
Pascoetrephus gen. n. Taking into account the above
features, this allows for an even more reliable diagnosis of
Zatrephus to be formulated.
Composition. e genus includes seven species, one
of which is described as new.
Distribution. Oriental realm.

Remarks. So far as currently known, Java, Indonesia
seems to host only this species of the genus. However, two
females Ihave studied, originating from Toegoe (Western
Java) and the Meru Betiri National Park (Eastern Java)
(Fig. 266), respectively, in my opinion belong to neither
Z.javanicus nor any other described species, very possibly
representing a new form.
Among the Z. javanicus specimens I have studied,
there are no females. However, based on the expression

of male and female features in a very similar species,
Z.pannosus, the degree of external similarity between the
sexes in Z.javanicus, almost without any doubt, ought to
be comparable.
e above two females, based on the structure of
elytral setation, appear to resemble most closely the female
of Z.pannosus, but in the apical one-quarter of the elytra
both show neither clear nor contrasting symmetrical
spots so characteristic of Z. pannosus and Z. javanicus
(in the latter, at least according to its males). Yet the
structure of the pronotum, in particular, the features
of setation, as well as the shape and, partly, sculpture
(Fig. 286) as observed in these females generally differ
markedly from those of Z. pannosus and Z. javanicus.
Besides this, there are some other, but mostly minor
differences. Nevertheless, in my opinion, additional
material is needed to establish of the species identity of
these Javanese females.
e differences between Z.javanicus and Z.pannosus
presented in the key below are to be considered preliminary,
at least partly so.
Distribution. Indonesia (Java).

Diagnosis. is new species is very similar to
Z.longicornis and Z.crassinus Holzschuh, 1992, especially
the former, but differs from both at least by features of the
male, in particular, the pronotum is slightly less clearly
broadened in the middle part and it shows a distinctly
more strongly developed setation of dense, recumbent,
light setae very considerably hiding the sculpture not
only on the sides, but also in the middle part of the disc,
as in Fig. 282 (cf. Figs 278–281, 283); by the somewhat
shorter antennae, as in Fig.274 (cf.Figs269–271,273), as
well as, compared to Z. longicornis, the clearly or much
more obliterate sculpture of the middle part of the disc
of the pronotum, whereas, compared to Z. crassinus, by
the absence of a clear tubercle at the base of the elytra on
either side of the scutellum, and by the almost continuous
setation of the elytra. Besides this, there are insignificant,
yet noticeable differences in the structure of the genitalia of
the new and compared species, in particular, in the shapes
of the parameres and endophallus, and the apex of tergite8,
as in Figs 287–294, 307–312, thereby, when compared to
Z.longicornis, fields with fine armature on the endophallus
are clearly less strongly developed and less clearly expressed
(inZ.crassinus, the endophallus has not been studied yet).
Description. Male. Body length 22 mm, humeral width
6mm. Coloration of integument mainly dark brown with a reddish
tint; eyes and head partly dorsally black.
Head with weakly developed antennal tubercles; with a
clear median groove between bases of antennae and on vertex,
with a distinct median fold between eyes; genae moderately
short, longitudinal diameter of lower lobe of eye about 1.5times
as long as genae; eyes weakly convex; gula with relatively small
transverse folds; neck predominantly with rough transverse folds;
submentum with a poorly distinguishable puncturation; antennae
reaching beyond apex of elytra by last antennomere; length ratio
of antennomeres1–11, 20:4: 18: 17: 17: 18: 26: 28: 27: 26:36;
antennomere1 with a clear dense puncturation; antennomere2
strongly transverse; antennomeres3 and4 strongly, 5thmoderately
inflated, as in Fig.368; last antennomere with a distinct appendage.
Pronotum barely transverse, 1.06 times as wide as long;
base 1.13 times as wide as apex; with a distinct constriction
near apex; on disc almost flat, with folds of different shape,
symmetrical, rough and coarse on sides, predominantly more or
less obliterated in middle area, and a flat median tubercle in basal
part in front connected with two longitudinal folds; generally this
sculpture strongly masked under a dense setation, as in Fig. 282
(inZ. longicornis, middle area of pronotal disc with symmetrical,
coarse or very coarse folds insignificantly masked under a setation
and distinctly visible, without any median tubercle in basal part,
but approximately in its stead with two symmetrical, longitudinal,
coarse and very coarse folds, as in Figs278–281).
Scutellum strongly narrowed towards apex, triangular, at the
very base shortly truncate.
Elytra moderately elongated, barely narrowed towards apex,
2.46 times as long as humeral width; with a small, somewhat
heterogeneous, dense puncturation; apical external angle obtuse,
sutural angle drawn into a clear, but small tooth, thereby both
angles masked under a dense setation.
Prosternum with a well-expressed transverse groove in
front of middle, with coarse irregular folds between this groove
and anterior border of coxal cavities; prosternal process barely
210 A.I. Miroshnikov
narrowed towards apex dorsally, with a strong apical tubercle;
mesosternal process without tubercle dorsally, between coxae
distinctly wider than prosternal process; mesosternum partly,
metasternum and sternites with a small dense puncturation;
metasternum with a gentle median groove; last (visible) sternite
broadly truncate at apex, last (visible) tergite with a well-developed
triangular emargination apically.
Legs relatively short; tarsomere 1 clearly shorter than
tarsomeres2 and3 combined.
Recumbent dense or very dense setation predominantly
clearly spotted, especially on elytra and venter, combines red/
reddish and white/whitish tones; red setae prevailing or strongly
dominating mainly on head dorsally and basal antennomeres,
whereas white setae clearly prevailing at least on elytra, as in
Fig.274; head, pronotum on disc and laterally, abdomen at apex,
most of antennomeres in apical part, legs mainly on trochanters
with more or less long, erect, partly suberect, sparse or individual,
thin setae.
Genitalia as in Figs 287, 291, 310–312.
Etymology. I am pleased to dedicate this new species
to my colleague and friend, Dr.SergeiI.Golovatch (Institute
for Problems of Ecology and Evolution, Russian Academy
of Sciences, Moscow, Russia), who, over a number of years,
has kindly provided his very important assistance to my
research.
Distribution. Vietnam.

original description). Heffern, 2013: 12 (Borneo, ailand).
Material. ♂, holotype (cCH) (photograph); 1♂ (NHMD)
(Fig. 269), E Malaysia, Sabah, Crocker Range, 04.2005 (local collector),

Distribution. is species was described from
ailand [Holzschuh, 1992]. It has recently been recorded
from Borneo [Heffern, 2013]. Based on the studied
material, Z.crassinus is being recorded here from Western
Malaysia for the first time.
Zatrephus spinosus Brongniart, 1890
(Figs 267, 284)
Zatrephus spinosus Brongniart, 1890: 183. Type locality:
“Bornéo” (according to the original description). Aurivillius, 1912:
62 (Borneo); Heffern, 2013: 12 (Borneo).
Material. 1♂ (cAM ex cDH) (Fig. 267), E Malaysia, Sabah, Trus
Madi Mt., 22.03.2000 (local collector), “Zatrephus spinosus Brongniart,
det. K. Hüdepohl [20]01”; 1♀ (cDH), same locality, 24.03.2004 (local

Park, 700m, 20.04.2013 (local collector), “Zatrephus spinosus Brongniart,
det.D.Heffern”; 1♀ (cNO) (photograph).
Morphological notes. According to the original
description, the body sizes are as follows: “Long. 25 mill.;
lat.4–6mill.” [Brongniar t, 1890: 184]. Besides this, the author
noted that “Le Muséum possède cette espèce de Bornéo.
M.M. Maindron lʼa recueillie à Singapore. Lʼéchantillon
type est enregistré dans le Catalogue do 1885 sous le n°
7059.” [Brongniart, 1890: 184]. Based on this information
and taking into account the entire text of the description,
it is quite difficult to unambiguously understand how many
specimens Brongniart used in his work. However, if one
considers that, for example, with a beetle length of 18.3mm
its width at the humeri is 5.1 mm (see below), then the
width indicated by Brongniart is likely to be approximate
and probably refers to a single specimen (i.e., the holotype
by monotype) with a body length of 25mm.
Remarks. I have no information concerning the
type specimen or specimens of this species. My repeated
attempts to relocate the material in the collection of
the Muséum national d’Histoire naturelle, Paris, kindly
undertaken at my request by Dr.GérardL.Tavakilian, have
failed. Nothing is known about the type(s) to my numerous
colleagues as well (their personal communications). Nor do
such data on this species exist in the literature ever since
the original description.
In the present paper, Z. spinosus is characterized,
based on four male and one female identified so by Karl-
Ernst Hüdepohl and Daniel J. Heffern (see the material
above). Hüdepohl might have seen the type.
e above specimens of Z. spinosus are kept in the
collection of Mr.Daniel J. Heffern (Houston, USA), who
kindly shared one of them with me. ey have a body length
of 18.3 to 23mm and a humeral width of 5.1 to 6.3mm.
Distribution. Eastern Malaysia; ?Singapore.
Zatrephus lumawigi Hüdepohl, 1990
(Figs 268, 285, 457)
Zatrephus lumawigi Hüdepohl, 1990a: 83, fig. 27. Type
locality: Philippines, Luzon, Mountain Province, Luzon (according
to the original description). Vives, 2009: 5 (“Zatrepus”, misspelling)
(Philippines, Mindanao, Davo).
Material. ♀(!), “Holotypus” (non♂; see Remarks) (ZSM) (Fig.268),
“Philippines, Luzon, VI.[19]86”, “Mountain Province”, “Holotypus ♂ (sic)
Zatrephus lumawigi mihi, Hüdepohl 1987” (Fig.457).
Remarks. Hüdepohl’s collection (ZSM) contains only
the “holotype” (Mrs.Katja Neven, personal communication
of November9, 2015). Ihave revised it, but it is a female(!)
(Fig.268). Itis this specimen that is depicted in the original
description [Hüdepohl, 1990a:83, fig.27], but the holotype
was claimed to be a male.
us, there is confusion in that publication. e
following is also noted there: “Zatrephus lumawigisp.nov.
(Fig. 27)... ♂: ...Antennae extending to apical 4/5 of
elytra; ...♀: Antennae hardly surpassing middle of elytra.
...Holotype ♂, length 24,5 mm, width 7,2 mm, and
Paratype♀, length 30,5mm, width 9mm, Luzon, Mountain
Province, VI.1986, coll. Lumawig, in authorʼs collection.”
[Hüdepohl, 1990a: 83].
In the female I have studied, with the labels reading
“Philippines, Luzon, VI.86” and “Mountain Province”, the
body sizes agree with those indicated by Hüdepohl for
“Holotype ♂”, while the length of the antennae coincides
with that marked for the female, which is clearly seen also
in Fig.27 in the original publication (see above). e sizes
of the “Paratype♀” as given by that author, namely, “length
30,5mm, width 9mm” obviously refer to the male which is
absent from his collection.
Distribution. Philippines.

Key to species of Zatrephus
1. Pronotum variously sculptured (Figs275–284), can only
be partly with transverse folds; apical external angle of
apical antennomeres not too sharp (Figs263–265, 267,

214 A.I. Miroshnikov
the shape of the submentum, the presence of a distinct
dorsal tubercle on the process of the mesosternum and
the clear longitudinal carina on the femora (Figs346,347,
cf.Fig.345) at their ventral margin on both sides, the general
character of setation, on the average the smaller body size,
the structure of the endophallus and some other features.
By the structure of the eyes, like the head as a whole, the
shape of the elytral apex, the presence of a longitudinal
carina on the femora, the shape and, partly, sculpture of
the pronotum, Pascoetrephusgen.n. resembles individual
representatives of the genus Xoanodera Pascoe, 1857, in
particular, X. trigona Pascoe, 1857, X.subtita Holzschuh,
2005 (Figs 339–343, 348, 349, 359–361, 374–376, 461)
and some other similar species, but differs very clearly at
least by the more robust body, the elytral sculpture and
setation, the structure of the antennae, especially the
shape of antennomeres3–5 in the male, the shorter and
more robust legs, the clearly claviform femora, and the
structure of the endophallus. e new genus can also be
compared to Xoanotrephus Hüdepohl, 1989 (Figs344, 350,
362, 373), but differs very clearly at least by characters of
the sculpture and setation of the dorsum, the shape of the
elytra, including their apex, the presence of a longitudinal
groove on antennomere 1 dorsally and of a longitudinal
carina on the femora, and the structure of the genitalia.
When detailing the structure of Pascoetrephusgen.n.,
the following features must be noted as being characteristic
of this genus: head short, with a more or less clear or deep
groove on vertex and, partly, between eyes; antennae of male
about reaching or barely extending beyond, but can also be
slightly or barely not reaching the apex of elytra (whereas
in Xoanodera, antennae of male at least in the compared
species listed above, one way or another, but seem to
always be longer than body; in Zatrephus, antennae of male
noticeably varying in length, from relatively short, slightly or
distinctly not reaching the apex of elytra up to significantly
exceeding the length of body, at least extending beyond the
apex of elytra by antennomere9, thereby having a rather
strongly elongated last antennomere), in female clearly, very
clearly or slightly shorter than body, antennomere1 with
a very wide, relatively deep, longitudinal groove dorsally,
occupying most of its length (while in Zatrephus and at
least in the compared species of Xoanodera, antennomere1
without groove dorsally), antennomere2 clearly transverse,
male antennomeres3 and4 clearly or strongly inflated, but
antennomere5 not inflated (Figs369,371), in basal part on
ventral side noticeably flattened, in female (Figs370,372)
not only 5th, but also antennomeres 3 and 4 flattened
(while both in male and female antennomeres 3–5 of
Zatrephus one way or another, but to a greater extent in
male, inflated, as in Figs 363–368, not flattened; both in
male and female Xoanodera antennomeres3–5 not inflated
at all, as in Figs 374–376), last male antennomere only
slightly longer than previous one (while in Zatrephus, last
antennomere clearly or much longer than previous one);
pronotum on disc in middle part not less than with two
very strong longitudinal folds (ribs) occupying most or a
significant part of pronotum length, its remaining surface
also with very coarse, irregular, partly transverse folds, as in
Figs377–392 (while in Zatrephus, at least disc of pronotum
cannot be with long, longitudinal, straight, very strong
folds, as in Figs275–286); setation of pronotum consisting
of very short or moderately short, suberect, recumbent,
monochrome-red or reddish (or mostly yellowish) setae
distributed in various ways, but always irregular, generally
from sparse and very sparse (Figs377–381) to quite dense in
places (Figs382–392), thereby capable of forming a peculiar
pattern resembling brackets, as in Figs382–389 (while in
Zatrephus, setation of pronotum in most cases at least
bicolour, more or less variegated, as in Figs275–286, but if
monochrome-red, then forming no pattern similar to that
in some Pascoetrephusgen.n.); elytra with a sharp or more
obtuse, but very well-expressed tooth, as a rule, in which
their apical external angle extended, with a heterogeneous
sculpture almost entirely or strongly hidden by dense
setation (in unabraded specimens); puncturation rough,
more or less sparse, irregular, one way or another gradually
decreasing towards apex or clearly smaller in apical part
and, besides this, with very small, relatively uniform,
moderately dense, more or less same punctures from base
to almost until apex of elytra (while in Xoanodera, at least
so in the compared species, elytra with a rough, coarse
and extremely coarse puncturation, thereby the latter
occupying significant fragments of elytral surface devoid
of dense setation, as in Figs 339–343; but if also a very
small puncturation present, then it can be observed only
as single punctures or insignificant in size, individual, few
fragments in different parts of elytra); recumbent setation
of elytra dense or very dense, all or almost all monochrome
(can only slightly differ in colour from main setation at
the very base of elytra), somewhat variable in coloration,
more often beige-yellowish, can be grayish, yellowish or
other, but only similar tones (while in Zatrephus, setation
of elytra polychrome, one way or another variegated,
often clearly motley and predominantly small-spotted
from red or reddish, sometimes brown or reddish-brown
setae in combination with whitish or yellowish setae, as
in Figs263–274; in Xoanodera, at least in the compared
species, setation, albeit monochrome, always forming this
or that pattern, leaving at least a significant part of elytra
surface bare, as in Figs339–343); prosternum with a well-
developed transverse groove in front of middle; endophallus
with clear or very sharply expressed fields of microtrichia, a s
in Figs313–320 (while in Zatrephus, at least in the species
studied, endophallus with barely or weakly expressed fields
of microtrichia, as in Figs307–312; in Xoanodera species
compared, endophallus, albeit with sharply expressed
fields of microtrichia, as in Figs 321–326, but location of
these fields, like shape of endophallus proper, very strongly
different from those in Pascoetrephus gen. n.). e new
genus resembles Xoanotrephus mainly by the habitus, the
structure of the head, including the eyes, the structure of
the legs and antennae, including antennomeres3–5 of the
male and, based on the similarity of these very features, it
was compared above with this genus.
Remarks. Pascoetrephus inscitus (Pascoe,
1857), comb. n., originally described in the genus
Zatrephus [Pascoe, 1857], was later transferred by that
author to the genus Xoanodera [Pascoe, 1869: 524].
Lacordaire [1868: 270] pointed to the transitional character
of P. inscitus comb. n. between Zatrephus (meaning
another, now the type species of the genus, Z.pannosus)
e longicorn beetle tribe Cerambycini Latreille, 1802 (Coleoptera: Cerambycidae: Cerambycinae) 215
and Xoanodera, namely, X.trigona (also the type species of
the genus). Gemminger [1872: 2805] and Aurivillius [1912:
63] treated inscitus in Xoanodera. Modern researchers
[Heffern, 2005, 2013; Holzschuh, 2009; Base de données...,
2017] include it into the genus Zatrephus, albeit some
specimens I have studied are labelled by Holzschuh as
“Xoanodera inscita Pasc. Holzschuh det. 2006” (see below).
Indeed, Pascoetrephusgen.n. combines some features
of the genera Zatrephus, Xoanodera and Xoanotrephus,
as partly noted above. However, the discovery of new
species described below and a detailed study of already
known taxa convincingly demonstrate both the taxonomic
independence and morphological isolation of the new genus
to be established, on the one hand, and the clearly expressed
homogeneity of all of its representatives, on the other hand.
Etymology. is new genus is dedicated to the
memory of Francis Polkinghorne Pascoe (1813–1893), a
famous English coleopterologist, who made invaluable
contributions to the knowledge of longicorn beetles,
especially of the Oriental Region. e name is formed in
combination with part of the generic name “Zatrephus” he
also established.
Composition. e new genus includes four species,
two of which are described as new, while one taxon gets a
full species status.
Distribution. Oriental realm.

Distribution. is species has hitherto been known
only from Borneo [Pascoe, 1857; Heffern, 2013]. Based on
the material studied, P.inscituscomb.n. is being recorded
here from Western Malaysia, as generally from Indochina,
for the first time. However, the label data “Pahang, Cameron
Highlands, Ringlet” for the specimen Ihave examined (see
above) may need confirmation.

Diagnosis. e new species seems to be especially
similar to P. inscitus comb. n., but differs clearly by the
somewhat peculiar sculpture of the pronotum disc, as
in Figs 382–385, its generally more strongly developed,
recumbent, red/reddish setation forming a characteristic
pattern in the form of brackets, as in Figs 382–385
(cf. Figs 377–381), the less deep median groove on the
vertex and, partly, between the eyes, the sparser, recumbent,
light setation in the apical part of the prosternum, the less
deep transverse impression at the anterior margin of the
submentum, the structure of the genitalia of the male and
female, including the clearly rounded apex of the styles,
as in Figs300, 302, 306, 313–315, 317 (cf. Figs 299, 301,
305, 316). Pascoetrephus klimenkoi sp. n. can also be
compared to P.heffernisp.n. and P.ranongensis Holzschuh,
2009, stat. n. et comb. n., but differs from both by the
clearly shorter setae at least at the apex and base of the
pronotum disc, as in Figs382–385 (cf.Figs 386–392), the
less strongly expressed and seemingly sparser puncturation
in the apical part of the elytra (discarding the very small
puncturation); it also differs from the former species by the
shape of the pronotum, as in Figs382–385 (cf. Figs 386–
389), the structure of the endophallus, including its shape
and clearly more strongly expressed fields of microtrichia,
as in Figs313–315,317 (cf.Figs318–320), from the latter
species by the generally less strongly developed setation of
the pronotum and the somewhat peculiar sculpture on its
disc, as in Figs382–385 (cf.Figs390–392).
Description. Body length 19.1–22.6 mm, humeral width
5.15–6.1mm, thereby holotype 22.4 and 6mm, respectively. Head
dorsally, eyes, fragments of coarse sculpture (folds) on pronotum,
partly apex of elytra and epipleura, also partly mandibles , antennae
and legs black or brown-black; remaining parts reddish brown and
dark reddish brown tones, however black or brown-black can also
be scuttelum and significant part of elytra while reddish brown and
dark reddish brown can be head dorsally.
Head with weakly developed antennal tubercles; with a
coarse, longitudinal, median fold partly between bases of antennae
and partly between eyes, with a median groove between most of
bases of antennae, with a clear or sometimes moderately deep,
more or less short, median groove on vertex just behind eyes or,
besides this, partly between eyes; eyes well-developed, relatively
strongly convex; genae short, about twice shorter than longitudinal
diameter of lower lobe of eye; submentum with a heterogeneous,
coarse and rough, sparse, partly confluent puncturation; neck
ventrally with sharp, transverse, predominantly short, numerous
folds; gula with clear transverse folds; antennae of male barely
reaching beyond apex of elytra by last antennomere or only
reaching it, in female very clearly not reaching the apex of elytra;
length ratio of antennomeres1–11 in male (holotype taken as an
example), 37:10: 40: 38: 33: 42: 47: 47: 46: 41:51, in female
(one of the paratypes taken as an example), 34:11: 40 : 32: 32:
41: 43: 40: 37: 32:34; antennomere1 with a very wide, relatively
deep, longitudinal groove dorsally, the latter taking up most of its
length; antennomere2 strongly transverse; antennomeres3–4 of
male strongly inflated; antennomeres 6–10 or 7–10 serrate; last
antennomere with a distinct appendage.
Pronotum distinctly longitudinal, 1.11–1.13 times as long
as width; base 1.2–1.22times as wide as apex; with a very sharp
constriction near apex; on disc in middle part with two very strong
longitudinal folds (ribs), the latters taking up most of pronotal
length; remaining surface with very coarse, irregular, partly
transverse folds, as in Figs382–385.

Diagnosis. e new species seems to be especially
similar to P.ranongensisstat.n. etcomb.n., but differs
at least by the somewhat peculiar shape and sculpture
of the pronotum, as in Figs386–389 (cf.Figs390–392),
the generally less strongly developed, recumbent,
red/reddish setation on its disc, but forming a very clear
and characteristic pattern in the form of brackets, as in
Figs 386–389 (cf. Figs 390–392), the peculiar shape of
the apical part of the tegmen, as in Fig.303 (cf.Fig.304).
Pascoetrephus heffernisp. n. can also be compared to
P.inscituscomb.n. and P.klimenkoisp.n., but differs from

the pronotum, shown in Figs 377–385, the comparatively
longer setae at least at the apex and base of its disc, as in
Figs386–389 (cf.Figs377–385), the more sharply expressed
puncturation in the apical part of the elytra (discarding
the very small puncturation); it also differs from the
former species by the generally more strongly developed,
recumbent, red/reddish setation of the pronotum, thereby
forming on its disc a pattern shown above in Figs386–
389 (cf. Figs 377–381), it differs from the latter species
by the structure of the endophallus, as in Figs 318–320

Distribution. is species is still known in the
literature only from the original description, based on
material coming from the south of ailand [Holzschuh,

Remarks. is genus is very widely distributed and
covers Africa, South, East and Southeast Asia, Australia
and Papua New Guinea, generally encompassing about
40 species [Ślipiński, Escalona, 2016; Base de données...,
2017].
Reviews of the African and Australian representatives
of the genus were made by Adlbauer [2002] and Ślipiński
and Escalona [2016], respectively. Papua New Guinea
supports only two species [Montrouzier, 1855; Gressitt,
1959]. e Asian group of species needs a detailed revision
and a diagnostic re-evaluation of the genus as a whole.

222 A.I. Miroshnikov
[1891], who established four taxa as its subgenera
(“sections”): Pachydissus s.str. (“verus”), Margites Gahan,
1891, Derolus Gahan, 1891 and Diorthus Gahan, 1891.
However, he later [Gahan, 1906] promoted his taxa to full
genera. is was accepted by Aurivillius [1912], Gressitt
[1951], Gressitt and Rondon [1970] and subsequent
researchers.
At the same time, Gressitt and Rondon [1970]
proposed to divide Pachydissus into two subgenera,
including Plavichydissus, described by Pic [1946] as a
separate genus. But they noted thereby: “Plavichydissus...
We are tentatively (sic) treating the latter as a subgenus
of Pachydissus.” Until now, such a subgeneric structure is
supported by some modern researchers (see, for example,
Base de données... [2017]).
In the present work, it seems to me impossible to
discuss in detail the systematic position of Plavichydissus
and its morphological features. However, provisionally
I would like to note that this taxon seems should not
be considered within Pachydissus. Representatives of
Plavichydissus are characterized at least by the peculiar
sculpture and setation of the elytra and pronotum, as well
as by the apex of the elytra devoid of clear or long teeth or
spines, by non-inflated antennomeres3 and4 of the male,
and only up to 28mm in length.
When determining, again just preliminarily, the
composition of Plavichydissus, besides its type species,
P.semiplicatus (Pic, 1926) [Pic, 1946], as well as Pachydissus
(Plavichydissus) grossepunctatus Gressitt et Rondon, 1970,
I would prefer to consider among its representatives, also
included therein earlier [Pic, 1946], P. rufipennis (Pic,
1923) and such species as Margites sulcicollis Gahan, 1893,
M.decipiens Holzschuh, 1989, M.aggregatus Holzschuh,
1999 and M. sodalis Holzschuh, 1999. However, further
studies are needed to clarify the diagnosis and species
composition of the genus Plavichydissus.
Pachydissus foveiscapus was described relatively
recently from Eastern Malaysia, but the author noted the
following: “Differentialdiagnose. Die neue Art ist schwierig
in eine der bekannten Gattungen unterzubringen. Nur
wegen des ziemlich kurzen Halsschildes stelle ich sie
vorläufig zu Pachydissus Newman, 1838.” [Holzschuh,
2011: 280–281]. Indeed, this species shows both a peculiar
combination of features and some structural details that
are generally typical of neither Pachydissus nor other
similar genera. In this regard, it seems to me appropriate
to distinguish P. foveiscapus in a separate, new genus
described below.
Genus Falsopachydissus Miroshnikov, gen. n.
Type species: Pachydissus foveiscapus Holzschuh,
2011.
Diagnosis. is new monotypic genus, the single
representative of which has hitherto been in the genus
Pachydissus (see above), differs сlearly from the latter
(except for one African species, keeping in mind only
the structure of the antennae; see Remarks below) by the
structure of the apical inner angle of antennomeres5–10
with a long sharp spine, the last antennomere being
strongly sharpened or extended apically into a very sharp
spine, as in Fig.396, the coarser, partly one way or another
shaggy, dense setation of the elytra, as in Figs 393–395, the
somewhat peculiar distribution of the pronotum setation,
as in Figs393–395,397, reminding of some Zatrephus.
Besides this, Falsopachydissus gen. n. is similar to
neither Asian forms (see, for example, Figs398, 399, 404)
nor numerous other representatives of Pachydissus in a
number of other features, differing by the more strongly
convex pronotum on the disc, the shorter antennomere1
with a strong or at least very clear impression near the base
dorsally, the distinctly tuberous (more clearly so in the
female) mesosternal process in the middle part on the sides,
the shorter and wider submentum, the shape of the inflated
apical part of antennomeres3 and4 of the male (in contrast
to species with thickened apices of male antennomeres3
and 4), the more strongly elongated last antennomere
of the male relative to the previous antennomere, the
somewhat peculiar shape of the apical external angle of the
elytra; differs also from some Asian species by the shorter
legs with more robust tibiae, and the clearly shorter meta-
and mesotarsi1.
For the purpose of a more complete characterization
of the new genus, it is also advisable to use some details
of the structure of its sole representative as shown in the
comparatively recent paper of Holzschuh [2011].
Very interesting is the strong similarity in the structure
of the antennae of Falsopachydissusgen.n. to another new
genus described above, Spinidymasiusgen. n., but the
former differs clearly from the latter by the more robust
body; the wider head, including the broader frons and
the more widely spaced bases of the antennae; the apical
inner angle of antennomere 5 with a long sharp spine
similar to the following antennomeres, except for the last
one (in Spinidymasiusgen. n., the apical inner angle of
antennomere5 can only be with a small denticle, but not
a long spine); the structure of the pronotum, in particular,
its being clearly more strongly convex on the disc and
there bearing a somewhat peculiar sculpture and setation;
the character of elytral setation (inSpinidymasiusgen.n.,
elytra, if with a continuous setation, then clearly silky or
distinctly patterned, but not shaggy).
At the same time, by the structure of the antennae,
at least by the presence and location of the spine at an
apical inner angle of antennomeres 5–10 and the shape
of most antennomeres, the new genus is similar to some
members of the genus Massicus Pascoe, 1867, in particular,
M.venustus (Pascoe, 1859), but differs very clearly in many
features, including the more robust body, the much less
strongly elongated elytra, the pattern of their recumbent
setation, the structure of the pronotum, the stronger and
shorter legs,etc.
Remarks. Among the African Pachydissus, only
one species, P. samai Adlbauer, 2000, has the apical
inner angle of the antennomeres 5–10 with a distinct
spine, but in many other features it is a characteristic
representative of the African group of species of this
genus (Adlbauer [2002] and his personal communication
of July 21, 2017). Besides this, in P. samai, in contrast
to Falsopachydissus gen. n., the last antennomere is
distinctly rounded apically (personal communication of
Dr.KarlAdlbauer of July21,2017).
e longicorn beetle tribe Cerambycini Latreille, 1802 (Coleoptera: Cerambycidae: Cerambycinae) 223
It is noteworthy that the apical inner angle of
antennomeres5–10 (inaddition, sometimes the3rd and4th
as well) carrying a more or less long spine, on the contrary,
is characteristic of one or another representative of the
genus Aeolesthes Gahan, 1890, with which some authors
compare Pachydissus [Ślipiński, Escalona, 2016]. However,
in Aeolesthes the last antennomere is the same as in
Pachydissus, neither sharpened apically nor drawn into a
sharp spine, but differs clearly from the new genus by the
same features as Pachydissus does, including the setation
of the pronotum and elytra, the sculpture of the pronotum
and a number of other features.
Until now, I have been able to study more or less
in due detail only the majority of Australian (see, for
example, Figs400–403), some Asian and several African
representatives of Pachydissus (including the type species
of the genus, the Australian P. sericus Newman, 1838,
Fig. 400), while the structure of the other species from
Australia, Asia and Africa, as well as the species from
Papua New Guinea, have been studied, based on literature
data alone [Gressitt, 1959; Holzschuh, 1991; Adlbauer,
2002; Ślipiński, Escalona, 2016 and others], as well as many
quality photographs and personal advice kindly provided to
me by Dr.KarlAdlbauer (Graz, Austria) on some African
forms. Several species of this genus remain unknown to
me, in particular, P.elegans Nonfried, 1895. Nevertheless,
already at this stage I tend to believe that Pachydissus and
Falsopachydissusgen.n. do not constitute a group closely
related supraspecific taxa. At least in the future, in the
case of a detailed revision of Pachydissus, the new genus
can hardly be justified as one of the latter’s subgenera. No
analogy with Dymasius and Spinidymasiusgen.n. seems to
be observed on this case (see above).
Etymology. In Latin, “falsus” means “false”, i.e., in
general the name is treated as “false Pachydissus”.
Composition. e new genus includes a single
species.
Distribution. Until now, this genus is known only
from Borneo.

Massicus is very similar to Neocerambyx J.omson,
1861, but the diagnoses of both genera require a further
detailed development, since the morphological differences
between them as proposed by various researchers are
generally unstable and can be used only for part of the
species. Neocerambyx or Massicus (= Mallambyx Bates,
1873) raddei Blessig, 1872 can be mentioned as a striking
example, when many publications treat the same species
in different genera [Blessig, 1872; Heyden, 1880–1881;

Diagnosis. e new species seems to be especially
similar to M. trilineatus (Pic, 1933) and M. taiwanus
Makihara et Niisato, 2014, but differs from both by the
clearly more strongly convex pronotum; the somewhat
peculiar, recumbent, light setation on its disc forming clearly
narrower longitudinal strips and significantly masking the
sculpture in the middle part of the disc (especially so in
the male), due to which the longitudinal strips look less
contrasting against the general background of the setation,
as in Fig. 409 (cf. Figs 412, 413); the shorter and more
obtuse tooth of the sutural angle of the elytra; the structure
of the apical external angle of antennomeres5–10 or6–10,
each bearing a well-developed, sharp spine; the somewhat
shorter antennae of the male; antennomeres3 and4 slightly
more strongly inflated apically in the male. Massicus
valentinae sp. n. can also be compared to M. pascoei
(J.omson, 1857), but differs clearly by the structure of the
pronotum, including its shape and setation, as in Fig.409
(cf. Fig. 414); the slenderer antennae; the smoothened
sculpture and the less strongly protruding apical external

strongly developed spine on antennomeres5–10 or 6–10;
the slightly shorter antennae in the male; the shape of the
inflated apical part of antennomeres3 and4 in the male;
the shape of the apical external angle of the elytra; the
clearly longitudinal antennal tubercles; the structure of the
submentum; the seemingly more uniformly curved external
margin of the mandibles; the slightly more strongly convex

Diagnosis. e new species seems to be especially
similar to M.valentinaesp.n., but differs by the somewhat
more robust body and antennae, especially so the basal
antennomeres; the shorter antennomere 3; the apical
external angle of antennomere 6 with a less strongly
developed denticle, but more robust (not so long) one on
the following antennomeres, except for the last one; the
structure of the pronotum, in particular, it being less strongly
convex on the disc at least in the male and somewhat less
strongly broadened at the middle in the male; the much less
strongly developed recumbent light setation in the middle
part of the disc only weakly masking its sculpture there, as
in Figs410,411 (cf.Fig.409); the apical sutural angle of the
elytra of the male with a more strongly developed tooth;
the sharper tubercle at the apex of the prosternal process;
the somewhat more strongly elongated mesosternal
process of the male; the more robust legs, at least so in
the male, as in Fig.407 (cf. Fig.406); and the larger body
in the male and female, respectively. Massicus ivanisp.n.
can also be compared to M.pascoei, but differs, partly like
M.valentinae sp. n., in the structure of the antennae, in
particular, the smoothened sculpture and the less strongly
protruding apical external angle of antennomere 1; the
more strongly developed denticle on antennomeres7–10;
many antennomeres less strongly elongated, including3rd
and4th, in which, additionally, the apical part is somewhat
differently inflated in the male; the shorter antennae in both
sexes; the somewhat peculiar sculpture of the pronotum, as
in Figs410,411 (cf.Fig.414); the less strongly developed
sutural tooth at the apex of the elytra; the clearly rounded
apical external angle of the elytra; the shape of the antennal
tubercles and the external margin of the mandibles; the
seemingly slightly more strongly convex eyes; the shape
and sculpture of the submentum and some other features.
Besides this, by the habitus, larger body, partly the
structure of the antennae and some other traits the new
species resembles Neocerambyx pubescens Fisher, 1936
(see Note), but differs in the slenderer basal antennomeres;
antennomere1 clearly less strongly broadened towards the
apex, with a smooth sculpture; the apical external angle
of antennomeres 7–10 with a more strongly developed
denticle; the more closely spaced dorsal lobes of the eyes;
226 A.I. Miroshnikov
e longicorn beetle tribe Cerambycini Latreille, 1802 (Coleoptera: Cerambycidae: Cerambycinae) 227
the significantly longer median groove on the vertex,
mainly hidden by dense setation between the bases of the
antennae; the less transverse pronotum and its generally
less strongly developed setation; the sculpture on the
ventral side of the head; and the more strongly elongated
and narrower process of the mesosternum in the male.
At the same time, evident similarities of M.ivanisp.n.
and M. unicolor Gahan, 1906 must be noted in the structure
of the antennae, the shape of the elytral apex and some
other details, but the former species differs clearly from the
latter at least by the coloration of the recumbent setation
of the dorsum, the less strongly protruding apical external
angle of antennomere 1, the structure of the pronotum,
including its somewhat peculiar shape and sculpture,
and the distribution of recumbent setation, the shorter
antennae of the female in which many antennomeres are
less strongly elongated.
Note. I have only been able to examine the holotype
male of Neocerambyx pubescens, kept in the USNM,
from a series of high-quality photographs of the habitus
and some structural details, all kindly provided by
Dr.AlexandrS.Konstantinov (USNM) upon my request.
Until recently N. pubescens was only known from
Java. Based on the data available at the Insecterra Forum
(http://insecterra.forumactif.com/), this species has
also been recorded from Borneo, at the same locality as
M. ivanisp. n. (Sabah, Trus Madi Mt.: http://insecterra.
forumactif.com/t24742-massicus).

convex; with a small dense puncturation; apical external angle
rounded; sutural angle in male drawn into a relatively long, well-
visible tooth, in female with a barely expressed denticle masked
under a dense setation.
Prosternum in apical one-third at middle clearly
tuberculiform elevated, with transverse, partly coarse and oblique
folds in apical part; prosternal process very clearly broadened
towards apex dorsally, with a strong tubercle at apex, wider in
female; mesosternal process without tubercle dorsally, between
coxae clearly wider than prosternal process; meso- and metasterna
and sternites with a small dense puncturation; metasternum with a
sharp median groove; last (visible) sternite at apex in male broadly

abdomen, legs mainly on trochanters with more or less long, erect,
partly suberect, sparse or individual, thin setae.
Etymology. is new species is dedicated to the
memory of my father, Ivan Polikarpovich Miroshnikov
(1928–1995), whose wise advice and very strong support I
received during all his life.
Distribution. Eastern Malaysia.
Genus Sebasmia Pascoe, 1859
Sebasmia Pascoe, 1859: 18. omson, 1864: 234; Lacordaire,
1868: 272; Gemminger, 1872: 2807; Gahan, 1906: 143; Aurivillius,
1912: 61; Heffern, 2013: 11.
Type species: Sebasmia templetoni Pascoe, 1859, by
monotypy.
Remarks. is Oriental genus includes eight species,
five of them described relatively recently, while one species
is described as new. One species previously referred to
this genus [Gahan, 1906: Sebasmia nigra] has since been
transferred to Microdymasius Pic, 1946 [Holzschuh, 2015].
Sebasmia is characterized by a peculiar combination
of features [Holzschuh, 2005] and differs clearly from all
similar genera. Only this genus seems to show one very
notable character distinguishing it from any other in the
tribe. In the male, the middle part or most of the ventral
side of the mesofemur has a dense or very dense brush
consisting of coarse, sometimes partly twisted, light setae
which can be located in a more or less clear or even deep
emargination.
Representatives of the genus have hitherto been
known only from Sri Lanka, Borneo and Sumatra [Pascoe,
1859; Gahan, 1906; Aurivillius, 1912; Heffern, 2005, 2013;
Holzschuh, 2005, 2006; Makihara et al., 2008; Base de
données..., 2017].
Based on the material studied (see below), the genus
Sebasmia is being recorded here from Indochina for the
first time.

Comparative material. Sebasmia speculifera Holzschuh,
2005: ♂, holotype (cCH) (photograph; Fig. 415); 1♂, paratype (cDH)
(Fig. 416), Malaysia, Sabah, Trus Madi Mt., 17.03.2000 (local collector),
“Cerambycinin. gen., n. sp. det. K. Hüdepohl 2001”, “Paratypus Sebasmia
speculiferan.sp. det.C.Holzschuh 2004”.
Diagnosis. is new species is very similar to
S. speculifera, but differs at least by the clearly less
strongly developed recumbent light setation both of the
pronotum and head dorsally, especially of the former, as
in Figs431–434 (cf. Figs 429–430), the male genitalia,
including the much shorter parameres, as in Figs422–
424 (cf. Fig. 421), the somewhat peculiar shape of the
apex of tergite8, as in Figs 426–428 (cf.Fig. 425); on
the average a larger body, as well as by the variable
composition of the coloration of the pronotal setation,
up to the complete absence of yellow/yellowish tones and
the presence of only a silver-white tone, as in Fig.432,
in most cases the slightly longer male antennae, as in
Figs417–418 (cf.Figs 415, 416), and some other minor
traits.
Description. Body length 17.9–21.7 or 24–26.4 mm,
humeral width 3.4–4.2 or 4.7–5.2 mm in males and females,
respectively, thereby holotype largest among the males, while ai
male smallest (body length of type specimens of S. speculifera,
including of two female, 13.6–19.2mm). Coloration of integument
mainly combines black and dark reddish brown tones; eyes black;
antennae and legs red-brown, antennomere1 darkest, but femora
can also be darker.
Head with well-developed antennal tubercles; with a
sharp median groove between bases of antennae and a more
or less sharp, sometimes weak groove between eyes partly and
on vertex; genae relatively short; eyes of male very large and
very strong convex, in female less strongly developed and less
strongly convex, in both sexes with large ocelli; submentum
with coarse punctures; neck with sharp transverse folds both
ventrally and laterally; antennae of male reaching beyond apex of
elytra by penultimate antennomere, sometimes by basal part of
last antennomere, in female distinctly not reaching the apex of
elytra or reaching it; length ratio of antennomeres1–11 in male
(holotype taken as an example) 32:11: 37: 35: 52: 58: 60: 58:
57: 55:68, in female (one of the paratypes taken as an example)
34: 12 : 44: 33: 48: 50 : 48 : 46: 45: 44: 61; antennomere1
mostly with a coarse, very dense and partly confluent, or mainly
confluent puncturation; antennomere 2 barely longitudinal
(given its longest inner side); last antennomere with a distinct
appendage.
Pronotum clearly/very clearly longitudinal, 1.2–1.29 times
as long as width; base 1.14–1.18 times as wide as apex; broadly
rounded on sides; with a sharp or very sharp constriction near
apex; with coarse or very coarse, mainly irregular, partly sinuous
folds and with a strong or very strong, median, keel-shaped,
longitudinal, shiny dorsally elevation located mostly in basal half,
as in Figs431–434.
Scutellum triangular, at apex more or less narrowly truncate.
Elytra strongly elongated, in male barely narrowed towards
apex, in female about parallel-sided, 3.14–3.45 times as long as
humeral width; slightly obliquely and broadly truncate at apex;
sutural angle with a clear or very clear tooth; with somewhat
heterogeneous, small, mostly gentle, sometimes sharper
puncturation.
Prosternum with rough or coarse, irregular, partly
transverse folds in apical part and with a transverse, more
or less clearly expressed groove in front of middle; prosternal
process with a well-developed, sometimes weakly expressed,
apical tubercle; mesosternal process without tubercle dorsally;
metasternum and sternites with a clear, dense, small
puncturation, somewhat heterogeneous in former; last (visible)
sternite at apex in both sexes with a small or more strong
developed emargination.
Legs relatively short; femora with a carina along each side;
mesofemora in male with a well-developed brush of very dense
light setae characteristic of the genus; tarsomere 1 slightly shorter
than tarsomeres2 and3 combined.
Recumbent setation on head dorsally mostly or completely
yellow/yellowish, as in Figs 431–434; on pronotum combined
with yellow/yellowish and silver-white tones or entirely silver-
white, thereby forming near apex no narrow fascia (Figs431–434)
(inS.speculifera, along with a clearly more strongly developed
setation than in S. indochinensis sp. n., a very well-expressed,
more or less narrow fascia located near apex, as in Figs429,430);
on elytra forming longitudinal strips of silver-white or, in
addition, partly yellowish tones, thereby in front of apex creating
a relatively large naked spot of triangular or oval shape on each
elytron, as in Figs 417–419; on venter completely or almost
entirely silver-white; elytral apex strongly or entirely masked
under a dense setation; head, pronotum laterally, prosternum
partly, legs on trochanters with more or less long, erect, partly
suberect, sparse or individual, thin setae.
Genitalia of male as in Figs422–424, 426–428; parameres ver y
short, peculiar in shape; tergite8 truncate apically, thereby can be
slightly emarginate (while in S.speculifera, parameres moderately
long, tergite8 broadly rounded apically, as in Figs421,425).
Etymology. e formation of the name of this new
species is related to its distribution in some countries of
Indochina Peninsula.
Distribution. Vietnam, ailand.

Indonesia (south of Borneo), on the other hand, for the first
time.
