Abstract: Long-headed pygmy grasshoppers (genus Ophiotettix Walker, 1871) from the New Guinean region
(New Guinea and adjacent islands) are taxonomically and biogeographically reviewed. For Ophiotettix and the
morphologically similar genera Paraspartolus Günther, 1939, Spartolus Stål, 1877 and Threciscus Bolívar, 1887
a new tribe is erected, Ophiotettigini trib. nov. This tribe is close to Clinophaestini Storozhenko, 2013, which is
placed here also under Metrodorinae. Bufonidinae syn. rev. are regarded to be synonymous with Batrachideinae,
not Cladonotinae, as previously considered. Statuses of currently known taxa of Ophiotettix are reviewed. The genus
now includes 40 species, seven of them previously described: O. buergersi Bolívar, 1929, O. cygnicollis Walker,
1871, O. limosina (Snellen van Vollenhoven, 1865), O. lorentzi Bolívar, 1929, O. modesta Bolívar, 1929 stat. rev., O.
scolopax Bolívar, 1929, O. westwoodi Bolívar, 1929 stat. rev. 33 new species are described and illustrated, namely:
O. amberiana sp. nov., O. bewana sp. nov., O. bomberaiensis sp. nov., O. brevicollis sp. nov., O. cheesmanae sp. nov.,
O. depressa sp. nov., O. liforma sp. nov., O. yriveriensis sp. nov., O. fritzpahli sp. nov., O. hansscholteni sp. nov.,
O. imbiana sp. nov., O. kaitani sp. nov., O. karimuiensis sp. nov., O. katharinae sp. nov., O. luce sp. nov., O. meggy
sp. nov., O. mountnokensis sp. nov., O. parvicollis sp. nov., O. projecta sp. nov., O. pulcherrima sp. nov., O. pushkari
sp. nov., O. quateorum sp. nov., O. rebrinae sp. nov., O. roesleri sp. nov., O. rohwedderi sp. nov., O. sanguinea sp.
nov., O. schapinae sp. nov., O. stallei sp. nov., O. storozhenkoi sp. nov., O. subbrevicollis sp. nov., O. telefominensis
sp. nov., O. tenuis sp. nov., and O. toxopei sp. nov. An annotated identication key to species is provided. Antennal
morphology (especially morphology of ve apical segments) is diagnostically important in the taxonomy of this group
and provides the best morphological character for species delimitation. Function of modied antennae is not fully
understood. Differences between species exist also in head morphology, facial colouration, and morphometrics.
Pygmy Giraffhoppers are a diverse group occupying most biogeographical regions of New Guinea North of the
Central range, while only few species inhabit areas south of the central range.
Key words: Orthoptera, Tetrigidae, pygmy grasshoppers, Discotettiginae, New Guinea, taxonomy, new species,
widened antennal segments, long head, horn.
Introduction
Pygmy grasshoppers (family Tetrigidae), an
old lineage of Triassic origin, are one of the most
diverse living Orthoptera groups, with more than
1900 species described to date (Song et al. 2015).
The highest concentration of species is found in
tropical regions, but there are representatives in
all biogeographical realms, from taiga to tropical
rainforests, exception being Antarctica and New
Zealand (Tumbrinck 2014a). Pygmy grasshoppers
can be easily recognized by their small body size
(usually smaller than 1.5 cm), their pronotum being
extended covering the abdomen, lack of tympana,
lack of arolium between the claws, the tarsal formula
being 2-2-3 and rst thoracic sternum modied into
a collar-like structure called sternomentum (Skejo
2016).
The island of New Guinea including its adjacent
satellite islands like Gebe, Waigeo and Yapen has
a very diverse pygmy grasshopper fauna. Species
inhabiting this region show an extremely large
variability of morphological structures like antennae,
head, palpi, pronotum, legs and abdomen as well
as a high number of endemic taxa. Hitherto about
30 genera and 100 species were recorded from
526
Telnov, D. et al. (eds) 2017: Biodiversity, Biogeography and Nature Conservation in Wallacea and New Guinea, III
New Guinea (Tumbrinck 2014a, 2014b, 2015;
Cigliano et al. 2017).
One of the morphologically most striking and
interesting groups of pygmy grasshoppers is the
genus Ophiotettix Walker, 1871 (formerly known
also as Tetricodina Westwood, 1874 and Tettigodina
Bolívar, 1887). It consists of colourful long headed
pygmy grasshoppers that, out of endearment, could
be named ‘Pygmy Giraffehoppers’. In the past the
genus had been assigned both to Discotettiginae
(Hancock 1907) based on the presence of
widened subapical antennal segments in certain
species (e.g. O. cygnicollis Walker, 1871, the type
species of the genus) and to Metrodorinae (e.g.
Günther 1939) based on morphological similarity
Paraspartolus Günther, 1939, Spartolus Stål,
1877 and Threciscus Bolívar, 1887 but is currently
without clear placement within Tetrigidae.
Only two Ophiotettix species (O. limosina and
O cygnicollis) had been described when Bolívar
(1929) made the rst revision of the genus,
describing three additional species (O. buergersi,
O. lorentzi and O. scolopax) and two subspecies
(O. buergersi modesta and O. b. westwoodi). Since
Bolívar’s revision, Günther (1938a, 1939, 1955)
added new localities for certain species, included
Ophiotettix in his identication key and discussed
the taxonomic position of the genus, but did not
describe new taxa or change the status of any of
the taxa described by then.
Based on the examination of over 750 specimens
the current study, while re-evaluating the status of
the described species, resulted in the recognition
and description of an additional 33 new species.
One possible new species photographed by various
Orthopterologists in the Muller Range (Papua New
Guinea) is not described here because of lack of
physical specimens. Results from the current study
were compared with previous studies dealing with
morphology of Ophiotettix (especially Bolívar 1887,
1929; Hancock 1907; Günther 1939). The current
study resulted in a new diagnosis of the genus and
a more detailed description of members of the
genus Ophiotettix, including characters previously
used as well as numerous characters not yet used
in detail until now. In addition the current study
led to a detailed generic description with notes
on variability of characters and with comments on
value / usefulness of certain characters in this group
of pygmy grasshoppers. An identication key to all
known species is provided. In addition Ophiotettix
is compared with morphologically similar genera in
the Metrodorinae and the morphological diversity
in particular of the antennae is discussed.
Materials and methods
Material
This study has been based on an examination
of the majority of the hitherto published specimens
besides a large number of additional specimens
(altogether over 750 specimens). All specimens
that arelisted have been examined unless stated
otherwise. Paratypes have been individually
numbered (3/14: paratype number 3 in a series
of 14). Abbreviations used for depositories
are presented below. Original label data are
supplemented with authors’ comments in square
brackets.
Photography
Various cameras using various lenses have
been used to take photos, all in macro mode by
using a stacking system with integrated scale bar
or with a macro-lens and millimetre paper. No
post-processing of photographs has been done.
Millimetre paper was placed close to photographed
specimen and subsequently used to construct a
scale bar included in the photograph, after which
the millimetre paper was deleted.
Morphology
The morphology of head, pronotum, legs,
and genitalia follows Devriese (1991, 1999) and
Tumbrinck (2014a) (Plate 104 gs 1-4).
Results from the current study were compared
with previous studies dealing with morphology of
Ophiotettix (Bolívar 1887, 1929; Hancock 1907;
Günther 1939). The current study resulted in a
new diagnosis of the genus and a more detailed
description of members of the genus Ophiotettix,
including characters previously used as well as
numerous characters not yet used in detail until
now. In addition the current study led to a detailed
generic description with notes on variability
of characters and with comments on value/
usefulness of certain characters in this group of
pygmy grasshoppers. Characters important for
distinction of hitherto described species are related
to head morphology and to morphometrics, thus for
the genus a detailed morphological description is
presented, while for each species, only diagnostic
descriptions of the characters essential for accurate
identication are presented.
Antennal morphology is the most relevant
character in separation of Ophiotettix species.

(Plates 104-124)
Different ratios are important (e.g. length of two
apical segments – segments 14+15 in ♀♀, 13+14
in ♂♂ compared to length of third segment from the
tip – segment 13 in ♀♀, 12 in ♂♂), measurements
of segments (e.g. comparison of width of third and
sixth antennal segment from the tip), colouration
(if three apical segments are white and strongly
contrasting with the rest or if they are dark, do they
bear silver bristles), and especially morphology of
third, fourth and fth antennal segments from the
tip (are their inner and outer margins lamellate,
strongly compressed, do they bear projecting edges
or spines).
The colouration of specimens including that
of antenna changes after xation, bright colours
(white, yellow, orange) usually becoming dark.
For the description of the colouration of certain
species photos from social networks (e.g. Flickr,
Facebook) have been used after the identication
had been conrmed. Variability of all the body parts
in colouration is very high in the genus and colours
may have high diagnostic value, since it seems that
members of this genus are very visually-oriented
grasshoppers.
Names for antennal segments were assigned
as follows: 1st scapus, 2nd pedicel, 3rd-7th (female) or
3rd-6th (male) basal segments, 8th-9th (female) or 7th-
8th (male) central segments, 10th-12th (female) or 9th-
11th (male) subapical segments, 13th-15th (female)
or 12th-14th (male) apical segments. Numeration
of the antennal segments follows Kuřavova et al.
(2017).
Measurements (Plate 104 gs 1-4)
Measurements were taken according to
Tumbrinck (2014a) including also three additional
measurements which are specically helpful in
Ophiotettix as follows:
Pronotum length: length of pronotum (dorsal or
lateral view; dorsal view is more accurate)
between the anterior and posterior margin (or
apex).
Pronotum width: width of pronotum (dorsal view)
between the apices of the lateral lobes of the
pronotum (or their ventrolateral projections).
Pronotum height: height of pronotum (lateral view)
from the ventral margin of the lateral lobes up
to the dorsal margin of the pronotum above.
Hind femur length: length of hind femur (lateral
view) from the tip of the dorso-basal lobe to the
tip of the knee (including the geniculartooth).
Hind femur width: greatest width of hind femur
(lateral view) between the ventral and dorsal
margin.
Vertex width: width of vertex (dorsal view) between
the hind margins of the lateral carinae of the
vertex including the carinae.
Eye width: greatest width of an eye (dorsal view) from
the outer side of the hind margins of the lateral
carinae of the vertex and the perpendicular
along the outer margin of the eye.
(I) Additional measurement: antennal length as
length of the agellum including scapus and
pedicel.
(II) Additional measurement: head length in lateral
view from the dorsal margin of the eyes to the
ventral margin of the gena (Plate 104 g. 1).
(III) Additional measurement: head index: length of
the neck (part of the head below the compound
eye) versus eye height in lateral view taken
parallel to neck’s extension (Plate 104 g. 1).
Mapping
For mapping purposes coordinates were
assigned to those localities for which only the
locality names were available. To assign coordinates
Google Earth, Google Maps and various hard
copy maps have been used (including maps from
collectors’ expeditions). Coordinates assigned to
localities are given in square brackets.

Results
Placement of Ophiotettix in Tetrigidae
Since establishment of the basis for the current
Tetrigoidea taxonomy by Bolívar in 1887, not a lot
has changed. After 1887 only few new subfamilies
and tribes were established (e.g. Discotettiginae,
Bufonidinae), serving primarily for better
identication and not being evolutionary units. The
only exception is subfamily Batrachideinae that
can be regarded separate family Batrachideidae.
Strong synapomorphies of the (sub)family are
(1) female spermatheca with two diverticula
(shared by all the members after Grant (1962), (2)
rectangular paranota (shared by all the members
except Ascetotettix Grant, 1956), (3) sulcate
dorsal margin of the fore and mid femora, (4)
antennae with more than 20 segments (except for
certain brachypronotal genera, such as Vingselina
Sjöstedt, 1921, Ascetotettix), (5) projected frontal
margin of the pronotum (except in certain genera,
e.g. Paurotarsus Hancock, 1900, certain Tettigidea
Scudder, 1862 species) and (6) fastigium of the
vertex convex and slightly projected above the
compound eyes. Despite of recent placement
of Bufonides Bolívar, 1898 within Cladonotinae,
we assign the genus here to Batrachideinae,
based on all the above presented statements (the
only anatomical feature we did not examine is if
Bufonides spp. possess two diverticula in female
spermatheca). Other members of brachypterous
Batrachideins from the Australian biogeographical
region also have bifurcation of the frontal costa
positioned lower than other Batrachideinae
and scutellum very wide (genera Wiemersiella
Tumbrinck, 2014b, Vingselina Sjöstedt, 1921).
Currently recognized subfamilies within
the Tetrigoidea are (1) Batrachideinae (with
Bufonidinae syn. rev. being synonymous with
Batrachideinae rather than Cladonotinae), (2)
Cladonotinae (including the tribe Xerophyllini), (3)
Lophotettiginae (monotypic, only genus Lophotettix
Hancock, 1909), (4) Metrodorinae (including tribes
Cleostratini, and Amorphopini), (5) Scelimeninae
(including tribes Criotettigini, Scelimenini, and
Thoradontini), (6) Tetriginae (including tribes
Dinotettigini, and Tetrigini), (7) Tripetalocerinae
(including two tribes, Tripetalocerini, and
Clinophaestini, but only 4 species altogether)
and 10 genera without placement in any of the
subfamilies (Cigliano et al. 2017).
The genus Ophiotettix is one of the
nomenclaturally oldest Tetrigidae genera, only
twelve genera being described before it. It is
the very rst endemic genus of New Guinea
to be described. Morphologically Ophiotettix
is one of the most striking genera of pygmy
grasshoppers. Up to now Ophiotettix was assigned
to the Discotettiginae. However Discotettiginae
are identical with Scelimeninae (Skejo, Pushkar &
Tumbrinck in press). Ophiotettix does not belong
to Scelimeninae. Genera such as Discotettix
Costa, 1864, Gavialidium Saussure, 1862,
Paragavialidium Zheng, 1994, and Kraengia
Bolívar, 1909 are characterized by tuberculated
body, the vertex being signicantly wider than
a compound eye, with tuberculated lateral and
median carina, the antennal grooves situated below
the compound eyes, a wide scutellum, the head
not being elongated with short occipital area and
toothed fore, mid and hind femora. On the other
hand, Ophiotettix shares numerous morphological
characters with the genera Spartolus Stål, 1877,
Paraspartolus Günther, 1939, Threciscus Bolívar,
1887 and thus the genus is placed here within
Metrodorinae. Comparison to other genera is
given in the generic diagnosis. This group can be
easily characterized by a few strong morphological
synapomorphies – (1) elongated head, (2) narrow
(almost not visible) scutellum, (3) high position of
the antennal grooves, (4) wings not visible, (5) apex
of the pronotum sharp and directed somewhat
upwards and (6) distal segment of the palpi
pennate.

Subfamily Metrodorinae Bolívar, 1887
Type genus: Metrodora Bolívar, 1887 (Central
and South America)
Type species: M. rana Bolívar, 1887 (type locality:
Peru, Alto Amazonas)
Comp osit ion : The subfamily Metrodorinae
includes two tribes, the Amorphopini Günther,
1939 with 3 genera and 8 species; the Cleostratini
Bolívar, 1887 (sensu Storozhenko 2016) with 16
genera and 48 species) and another 71 genera
with more than 540 species (Cigliano et al. 2017)
without tribal placement. Of those, the tribe
Ophiotettigini trib. nov. is erected for Ophiotettix,
Spartolus, Paraspartolus, and Threciscus.
Dist rib utio n: Across all continents except Europe
and Antarctica. Africa including Madagascar (22
genera, 85 species), North America (1 genus, 1
species), South America (15 genera, 78 species.),
temperate Asia (20 genera, 216 species), tropical
Asia including Malesia, Melanesia and Papuasia
(42 genera, 163 species), Australia (2 genera, 3
species) (Skejo 2016).
Diag nos is: characterized by having the median
ocellus and the antenna placed below the eyes, a
relatively small divergence of the rami of the frontal
costa not forming a wide scutellum, and a similar
length of the rst and third segments of the hind
tarsus (Pavón-Gonzalo et al. 2012). Many species
of Metrodorinae also exhibit the posterior angles
of the lateral lobes of the pronotum produced
outwards (the main character used when the
subfamily was established) often becoming acutely
spinose. All these characters together separate
the subfamily from the other eight subfamilies of
Tetrigidae, although none of them is enough to
characterize Metrodorinae by itself.
Tribe Ophiotettigini trib. nov.
Type genus: Ophiotettix Walker, 1871 (New
Guinea and adjacent islands)
Type species: O. cygnicollis (type locality: NW
New Guinea: Dorei)
Deri vati o n omin is: The tribe is named after the
genus Ophiotettix.
Comp osit ion : 4 genera have been assigned to
the Ophiotettigini, Ophiotettix with 40 species,
Paraspartolus with 1 species, Spartolus with 2
species and Threciscus with 1 species
Distr ibu tion : Distributed across New Guinea and
its satellite islands (Ophiotettix) and the Philippines
(Paraspartolus, Spartolus and Threciscus).
Diagnostic characters Ophiotettigini: Head
– Head very elongated, occipital area very long,
eyes pointed and produced above the vertex so the
vertex is not visible in lateral view. Vertex extremely
narrow, visibly narrower than a compound eye, not
produced in front of the eyes, slightly tapering, not
truncated, its median carina long and distinct, the
lateral carinae low almost indistinct. Fossullae
absent, the bifurcation of the frontal costa between
the eyes indistinct because of an extremely narrow,
indistinct scutellum. Antennae long and 14 (male)
- 15 (female) segmented, the dorsal margin of the
antennal groove slightly above the ventral margin
of the compound eye. Between the eyes lateral
ocelli are present. Thorax – Tegmina and wings not
evident. Pronotum smooth, covered by numerous
ne pits, the anterior margin truncated, apex slightly
decurved upwards, the prozona slightly elevated in
comparison to other parts of the pronotum, prozonal
carinae evident, median carina weak, but present
across the whole length of the pronotum, humeral
angle widely oblique without depressions, lateral
lobe triangularly shaped, projected outwards. Fore
and mid femora carinated dorsally, slender, and
smooth. Hind femora elongated, smooth, with
evident transversal carinae in the external area,
genicular tooth strong, antigenicular tooth weak,
indistinct. Abdomen – ovipositor elongated.
Comparative notes of the included genera:
In the description above we presented shared
characters. Genera of the tribe Ophiotettigini can
be distinguished by size (Paraspartolus smaller
than 9 mm, while members of other genera being
longer than 12 mm), colouration (Paraspartolus
being greyish-brownish in colour, while members
of other genera colourful, with red, yellow, orange,
white, and dark tones), maxillar palpi morphology
(having very widened, folliaceous last segment
in Ophiotettix, and Spartolus, while not modied
in Paraspartolus and Threciscus), pronotum
morphology (brachypronotal in Paraspartolus, not
covering whole abdomen, in Ophiotettix usually
covering or almost covering whole abdomen,
and covering whole abdomen in Spartolus, and
Threciscus), morphology of the lateral lobes (with
strong spines in Spartolus and Threciscus, without
projections in Paraspartolus, while broadly acute in
Ophiotettix).
Notes for the further research on the
taxonomy of the tribe: Recent changes in
Metrodorinae taxonomy (Cadena-Castañeda &
Cardona 2015; Storozhenko 2016) gave a new
view on the taxonomy of genera with projected
frons, or fastigium of the vertex (tribes Cleostratini
or Miriatrini - pygmy unicorns). However, certain
530
Telnov, D. et al. (eds) 2017: Biodiversity, Biogeography and Nature Conservation in Wallacea and New Guinea, III
pygmy unicorns should probably be assigned
to Ophiotettigini. These are (1) Rhopalotettix
vietnamensis Storozhenko, 2015, which is very
distant from other Rhopalotettix in having head
signicantly exerted above the pronotal surface,
not in the lever or slightly exerted, antennae
are 15-segmented, not 13-segmented as other
species, evident median carina of the vertex,
not depressed vertex as in other species, very
exerted eyes, not ‘sessile’ as in other members of
the genus, and extremely narrow scutellum, not
evident as in other species, (2) Halmahera nana
Storozhenko, 2016, brachypronotal taxon from
Halmahera Isl. with projected vertex, but also
strongly exerted head, pointed eyes, extremely
narrow scutellum, long median carina of the vertex,
pointed and slightly upwards curved apex of the
pronotum, and elongated legs. There are also
morphological similarities with Hirrius punctatus
(Stål, 1877) and relatives (morphology of the
pronotum, however there are numerous differences
in head morphology, especially not elongated
general appearance, and wide vertex), formerly
Discotettiginae member whose taxonomic position
is still not clear. Cladistic analysis is necessary
to test which groups of Tetrigidae are the closest
relatives to members of this morphologically
specialized group. Furthermore, taxa of future
taxonomic revision are Thyrsus tiaratus Bolívar,
1887 and Uvarovithrysus uvarovi (Günther, 1935),
the head morphology of which ts Ophiotettigini
description. Better diagnoses and descriptions of
pygmy unicorns’ genera and species are needed
in future because the former tribes combine taxa
with very different morphology. A character shared
by Ophiotettigini and the mentioned pygmy unicorn
genera is a low position of the median ocellus. This
character and its taxonomic importance will be
investigated in future (for comments on taxonomy
of pygmy unicorns consult Silva et al. (2017)). We
place Halmahera, Uvarovithrysus and Rhopalotettix
preliminary into Ophiotettigini trib. nov., because
those taxa are certainly more related to Ophiotettix
- like genera than to Cleostratus (this is one of the
re-arrangement acts for genera hitherto placed in
Cleostratini, see Cigliano et al. 2017, Orthoptera
species le. Tribe Ophiotettigini is close to the tribe
Clinophaestini Storozhenko, 2013 (members are
genera Birmana Brunner von Wattenwyl, 1893 and
Clinophaestus Storozhenko, 2013, which seem to
be synonymous after our preliminary examination of
Birmana and Clinophaestus specimens). This tribe
is morphologically not related to Tripetalocerini,
thus we move it to Metrodorinae: Clinophaestini.
In future, well dened Clinophaestini and
Ophiotettigini trib. nov. could together form tribes of
a subfamily different from Metrodorinae, because
they are very distantly related to Metrodora-genera
group in S America. Clinophaestini members have
prolonged fastigium of the vertex in the same way
as nymphs in Ophiotettix, antennal edges have
very similar shape. The number of the antennal
segments is different - 11 in Clinophaestini. Shape
of antennal segments is similar to some Ophiotettix
species, the main difference being that there are
ve extremely widened antennal segments that
have very lamellate inner margin and have the
distal inner tip protruded into sharp edge, long tip,
or spine. Nymphs usually have smaller number of
antennal segments than fully grown adults and this
implies a neotenic origin. All these characters make
it evident how related to Ophitettigini they are.

Type species: Ophiotettix cygnicollis Walker,
1871 by original monotypy
Derivatio nominis: Ophiotettix has derived from
the Ancient Greek words ΄οφις (ophis, meaning
snake or serpent) referring to elongated head and
τέττιξ (tettix, meaning grasshopper or cicada).
Description: Head - Head elongated, the head
index varying from <1 (in O. parvicollis sp. nov.)
to >3 (longest in O. scolopax), fastigium generally
obliquely rounded or obliquely angular, at or deep
(= concave), anterior border a little bit tapering,
not truncated, sometimes slightly projected before
the eyes in adults forming small horn, transverse
carinae diagonal to the median carina, bulging,
lateral carina weakly elevated, indistinct, in some
species almost absent, in other species present and
running parallel, divergent and convergent towards
the tip. Vertex slightly attened or deep (concave),
with a concave part between the median carina
and the eyes in some species, visibly narrower
than a compound eye in dorsal and lateral view,
the medial carina slightly elevated, in some species
visible over the eyes in lateral view; from the middle
of the eye to the frontal part of the fastigium higher;
from the middle of the eye length to the anterior
tip of the pronotum visible as a ssure. Fossullae
absent or extremely reduced, not visible. Frontal
costa in lateral view strongly arched, projected
before the eyes, from between the lateral ocelli
to the median ocellus, the bifurcation between
the eyes and between the lateral ocelli, in frontal
view extremely narrow, the scutellum so narrow
that it seems that there is no bifurcation, ending
at the medial ocellus, under the medial ocellus
visible as bright stripe or ssure. Superior (lateral
or paired) ocelli situated a little above the middle
of the eyes. Eyes suboval, slightly exerted, their
dorsal margin extending a little above the fastigium
situated at the tip of a long neck. Antennae very
long, almost as long as whole body, 15-segmented
in females, 14-segmented in males, the upper
margin of the antennal grooves situated above
the lower margin of the eyes. Thorax - Pronotum
short (brachypronotal state), low and tectiform,
undulated, covering whole or almost whole
abdomen, discus smooth, covered with many ne,
sunken dots. Anterior margin straight, truncated,
but can vary and be a little bit extended in the
middle (this feature is not signicant identication
character), no depressions behind the shoulders.
Median carina very low, present as a light ssure
over the whole pronotum. Prozona higher than the
rest of the pronotum, as well as the part above the
connection of hind femora. Prozonal carinae long,
parallel, not elevated - two light, pale coloured
ssures. Humeral angles inconspicuous, widely
oblique, not armed. Interhumeral carinae low, but
well visible as two bright stripes on the discus.
Infrascapular area broad with a concave part above
the connection of the hind femur, with numerous
large pits (usually larger than those on the discus).
Lateral lobes strongly curved laterad, broadly acute.
Pronotal process extended in a spine, extremely
narrow, not truncated, not inverted. Extralateral
carina continuous to the sulci as bright stripe.
Wings. Tegmina not visible (reduced and covered by
pronotum), wings (= alae) not visible (reduced and
covered by pronotum) - ightless species. Legs.
Anterior femur very slender, smooth, not undulated,
without lobes. Anterior tibia slender, elongated,
armed with small spines from the mid of its length
and further. Middle femur very slender, smooth, not
undulated, without lobes, with a few hairs. Middle
tibia slender, elongated, armed with small spines
from the 1/3 of its length and distally. Hind femur
very slender (more than 4x, in most species more
than 6x longer than wide), without tubercles, with
smooth and low transversal carinae in the external
lateral area of the femoral. Dorso-external and
ventro-external carina smooth, without projections.
Hind tibia uniformly brown, not annulated with pale
rings. Genicular tooth clearly visible, long and acute.
Antegenicular tooth indistinct, very small, almost
absent. First and third article of the hind tarsi
almost equal in length. Pulvilli of the mid article
of the hind tarsus obtuse, rounded, not sharp and
pointed. Abdomen - Ovipositor elongated.
Comments on nymphal morphology. In nymphs of a
lot of species fastigium is long and projected in earlier
instars (depicted in Günther 1938b), decreasing
in size with every moulting, as nymph grows. Long
vertex in nymphs seems to be connected with head
prolongation - practically during development eyes
move higher and higher towards the tip of the
vertex and the part above the eyes is becoming
shorter and shorter. It is interesting that long vertex
in nymphs (as well as in most Cleostratini) provides
very good mimicry. Predator rstly thinks it is small
branch or something elongated like that, and if it
wants to strike, it will not be sure which is the head
532
Telnov, D. et al. (eds) 2017: Biodiversity, Biogeography and Nature Conservation in Wallacea and New Guinea, III
tip and which is tip of the pronotum, giving nymphs
of Ophiotettix and pygmy unicorns (Tetrigidae
genera with prolonged vertex) time to jump and
escape safely.
Generic diagnosis: See comparative notes
under the tribe Ophiotettigini nov.
Colo ura tion : Head usually dark, only in some
species bright, tip of the fastigium often brightened,
frons below the median ocellus and above the
clypeus with highly complicated species specic
colour markings varying from almost black or with
a bow tie shaped pale marking above the clypeus to
highly decorated with one or more markings above
the clypeus, antennae completely black, dark-grey,
or dark-brown, sometimes apical and subapical
segments brightly coloured. Pronotum usually dark,
(black, brown, grey, dark-brown, dark-grey), in some
species bright, with very contrasting median carina
(yellow, orange, reddish, or white), with a pale
coloured region (orange, pale orange, white, yellow)
of variable width between the internal and external
lateral carinae running from the fore margin to the
humeral angle and to the tip of the pronotum along
the prozonal carinae, the area around the tip of the
lateral lobe usually pale coloured, one coloured
or a mixture of bright colours (e.g. white, orange,
yellow). Fore and middle femur dark, occasionally
with a pale stripe along the dorsal margin. Fore and
middle tibia dark, the proximal tarsal segments
often pale coloured, the distal ones dark with a
pale coloured dorsal margin. Hind femur completely
dark, or dark with the area above the dorso-external
carina and below the ventro-external carina with a
narrow to wide white stripe along the entire length.
Hind tibia dark, the rst tarsal segment usually
bright, the second segment pale, the third segment
dark, with a pale coloured dorsal margin.
Dist rib utio n ( Map 1): The genus is currently
known from New Guinea and some of its satellite
islands (Yapen, Gebe and Waigeo) with most
species found North of the Central Range Mts.
Up to now there are no records from the adjoining
Moluccas islands.
Comp osit ion : Altogether 40 species are now
assigned to the genus Ophiotettix: 5 hitherto
described species supplemented with two
subspecies of O. buergersi (O. buergersi modesta,
O. buergersi wewstwoodi) here elevated to the
species level and 33 species described here as
new to science). Species can be ordered into 12
groups according to morphological similarities as
follows:
(1) ‘Brevicollis’ species group (Map 1): O. brevicollis
sp. nov. (Short-neck Giraffehopper), O. parvicollis
sp. nov. (Petite Giraffehopper), O. roesleri sp. nov.
(Petite Rösler’s Giraffehopper), O. subbrevicollis sp.
nov. (Shortish-neck Giraffehopper)
Recognition: The four species of this group are
characterised by short heads and the antennal
segments without specialized broadly lamellate
antennal segments
(2) ‘Buergersi’ species group (Map 1): O. buergersi
(Bürgers’ Giraffehopper), O. imbiana sp. nov.
(Imbia Giraffehopper), O. modesta stat. rev.
(Modest Giraffehopper), O. rohwedderi sp. nov.
(Rohwedder’s Giraffehopper), O. sanguinea sp.
nov. (Bloody Giraffehopper), O. schapinae sp. nov.
(Šapina’s Giraffehopper), O. tenuis sp. nov. (Elegant
Giraffehopper)
Recognition: This species group is
heterogeneous, including seven species without
pale apical segments that are strongly contrasting,
with modied subapical antennal segments bearing
lateral edges protruded into acute, right angle, or
spine, fourth antennal usually bearing spine or
protruded angle directed forwards, fth antennal
segment not modied or produced backwards or
bearing small and low angular projection.
(3) ‘Cygnicollis’ species group (Map 1): O.
amberiana sp. nov. (Amberi Giraffehopper),
O. cygnicollis sp. nov. (Short-neck Pennate
Giraffehopper), O. pushkari sp. nov. (Pushkar’s
Pennate Giraffehopper), O. storozhenkoi sp. nov.
(Storozhenko’s Pennate Giraffehopper)
Recognition: This group includes four species
characterized by relatively long necks and
extremely wide subapical antennal segments, third
segment being ‘cup’–like. General appearance
dark, antennae dark. The group resembles both the
‘Toxopei’ species group and the ‘Buergersi’ species
group.
(4) ‘Hansscholteni’ species group (Map 1):
O. hansscholteni sp. nov. (Hans Scholten’s
Giraffehopper)
Re co g ni t io n : This group includes only one species
characterized by a long head, and elongated
antennal segment with protruding edges. The
species (group) is related to the ‘Brevicollis’ species
group.
(5) ‘Limosina’ species group (Map 1): O. bewana
sp. nov. (Bewani Giraffehopper), O. bomberaiensis
sp. nov. (Onin Slender Giraffehopper), O. depressa
sp. nov. (Depressed Slender Giraffehopper), O.
liforma sp. nov. (Lowland Slender Giraffehopper),
O. limosina (Godwith Giraffehopper), O. luce sp.
nov. (Luce’s Giraffehopper), O. mountnokensis sp.
nov. (Mount Nok Giraffehopper), O. projecta sp.

(Plates 104-124)
nov. (Excited Giraffehopper), O. scolopax (Giant
Giraffehopper)
Rec ogn it io n: A heterogeneous group of nine
relatively long headed species with liform
antennae without pale tips lacking specialized
segments. Resembles the ‘Lorentzi’, ‘Pulcherrima’
‘Brevicollis’ and ‘Buergersi’ species groups likely
to contain species with ancestral characters, from
which more specialized, eastern forms derived.
(6) ‘Lorentzi’ species group (Map 1): O. lorentzi
(Lorentz’s Giraffehopper)
Rec ogn it io n: This group includes only one
species characterized by a long head and having
third, fourth and fth antennal segment from the tip
widened and rounded. This species resembles the
‘Katharinae’ species group some characters being
intermediate between species of the ‘Limosina’
and ‘Toxopei’ species group.
(7) ‘Katharinae’ species group (Map 1): O.
yriveriensis sp. nov. (Fly River Giraffehopper),
O. kaitani sp. nov. (Kai Tan’s Giraffehopper), O.
karimuiensis sp. nov. (Karimui Giraffehopper), O.
katharinae sp. nov. (Katharina’s Giraffehopper), O.
quateorum sp. nov. (Quate’s Giraffehopper)
Rec ogn it io n: The group consists of ve species
and is characterized by dark antennae, subapical
segments with lamellate inner margins, third
antennal segment from the tip without long
protruded tip, fourth segment from the tip parallel
or convergent towards the tip, fth antennal
segment from the tip with the dorsal margin straight
or curved backward. In colouration, species of this
group resemble those of the ‘Brevicollis’ species
group and those two groups are probably closely
related, likely also mixed.
(8) ‘Pulcherrima’ species group (Map 1): O.
pulcherrima sp. nov. (Beautiful Giraffehopper), O.
rebrinae sp. nov. (Rebrina’s Giraffehopper)
Recognition: This group consists of two species
with a colourful appearance characteristic by a long
head, slender dark antennae with pale coloured,
very contrasting apical segments. This group is
probably related to some representatives of the
‘Limosina’species group.
(9) ‘Stallei’ species group (Map 1): O. stallei sp. nov.
(Stalle’s Giraffehopper)
Rec ogn it io n: This group includes only one
species characterized by relatively short head
(head index <1.25), projected fastigium (minute
horn), antennae with segments widened towards
the tip. The species shows nymphal characters and
could be regarded as a neotenic species related to
the ‘Brevicollis’ species group.
(10) ‘Telefominensis’ species group (Map 1): O.
telefominensis sp. nov. (Telefomin Giraffehopper)
Rec ogn it io n: This group includes only one
species characterized by the fastigium distinctly
protruded into a horn, the antennal segments
not being specialized, with the margins widened
towards the apex. The species has some nymphal
characters, and could be regarded as a neotenic
mountain species. Species with a protruding but
less produced fastigium are found also in other
species groups and it is not clear to which species
(group) is this one related.
(11) ‘Toxopei’ species group (Map 1): O. toxopei sp.
nov. (Toxopeus’s Giraffehopper)
Rec ogn it io n: This group includes only one
species characterized by having the third antennal
segment from the tip similarly widened as the
fourth segment, both being broadly lamellate. This
group is related to the ‘Cygnicollis’ species group.
(12) ‘Westwoodi’ species group (Map 1): O.
cheesmanae sp. nov. (Cheesman’s Giraffehopper),
O. fritzpahli sp. nov. (Fritz Pahl’s Giraffehopper),
O. meggy sp. nov. (Meggy’s Giraffehopper), O.
westwoodi stat. rev. (Westwood’s Giraffehopper)
Rec ogn it io n: This group includes four species
- three of which are characterized by pale apical
antennal segments and at least one antennal
segment with a protruding tip at the inner margin,
the fourth antennal segment from the tip of the
antennae. O. fritzpahli sp. nov. with morphological
characters between the ‘Westwoodi’ and the
‘Pulcherrima’ species groups is tentatively placed
in this group.

Notes : Snellen van Vollenhoven (1865) writes
about one male and females from “Gebeh” (leg.
Bernstein) and gives description and two drawings
of the species. No authors designated types (valid
lectotype), but a female had a “Type” label which
may originate from C. Willemse while three other
specimens have a “Cotype” label. Here we designate
the female with the “Type” label for the lectotype
and other specimens including a specimen from
OUMNH paralectotypes. The aforementioned
male has not been traced yet. Photo of a male
specimen (Plate 124 g. 3) and a nymph taken by
Marek Stefunko (2011) from Arfak Mountains ts
description of this. No other Ophiotettix records
are known from Arfak Mountains. Other records
of Ophiotettix limosina in literature are wrongly
identied specimens (including those published by
Bolívar (1898, 1929) and Günther (1936)).
Desc rip tion : All antennal segments rounded,
dark and very long (>10 mm). Lateral carinae of the
vertex convergent. Tip of the fastigium brightened.
Vertex, in frontal view, attened. Pronotum with
yellow stripes. Body dark with yellowish pronotal
carinae and characteristic pale clypeal marking.
Measurements lectotype ♀: pronotum length 10.53
mm, pronotum lobe width 4.16 mm, pronotum
height 2.04 mm, hind femur length 10.40 mm, hind
femur width 1.85 mm, vertex width 0.43 mm, eye
width 0.68 mm, antenna length 11.05 mm, head
length 5.50 mm, head index 1.41. Measurements
1 ♂ (Klamono Oilelds), pronotum length 9.75 mm,
pronotum lobe width 4.03 mm, pronotum height
2.10 mm, hind femur length 9.88 mm, hind femur
width 1.65 mm, vertex width 0.53 mm, eye width
0.62 mm, antenna length 10.66 mm, head length
4.60 mm, head index 1.33.
Differential diagnosis: O. limosina is the only
species with all antennal segments totally rounded
and no edges visible. The species is on the rst
sight similar to other species of the Limosina
species group, but is easily separated from all of
them by presented character.
Distribution: O. limosina is found on Gebe Island
west of Waigeo. Gebe belongs administratively to
North Moluccas but it is on the half way between
Waigeo and Halmahera and was probably
connected with Waigeo and New Guinea in the Ice
Age. Other specimens are recorded from Waigeo
and in the western part of Doberai Peninsula.
Probably this species is distributed from the west
of Doberai Peninsula to the Arfak Mountains in the
northeastern part.

Note: On the island of Gebe O. limosina is hitherto
the only reported species. Very doubtful record
because it is not possible to identify these nymphs,
especially without antennae. With antennae it is
possible to differ nymphs from O. cygnicollis from
species with rounded antennae like O. limosina.
Hence we place this young specimen as Ophiotettix
sp.
Desc rip tion : Apical and subapical segments
of the antennae black, other segments more
brownish. Third to fth antennal segments from
the tip (segment 11+12+13 in ♀♀, 10+11+12 in
♂♂) like a “cup” with a long tip at the inner margin.
Apical segments with narrow whitish bristles.
Two apical segments (segments 14+15 in ♀♀,
13+14 in ♂♂) together as long as third segment
from the tip (segment 13 in ♀♀, 12 in ♂♂). Three
apical segments (segments 13+14+15 in ♀♀,
12+13+14 in ♂♂) together shorter than fourth
segment from the tip (segment 12 in ♀♀, 11 in
♂♂). Outer margin of the fourth antennal segment
from the tip (segment 12 in ♀♀, 11 in ♂♂)
lamellate and curved. Lateral carinae convergent.
Tip of the fastigium dark. Vertex, in frontal view at,
median carina higher than lateral carinae of the
vertex. Pronotum with yellow stripes. Visible part
of the abdomen yellow. Measurements syntype

0.68 mm, antenna length 6.88-8.25 mm, head
length 4.55-4.95 mm, head index 1.22-1.23.
Differential diagnosis: O. cygnicollis is one of
the species without pale coloured apical antennal
segments, characteristic in subapical antennal
segments with lamellate inner margins and
the third antennal segment from the tip with a
distinct protruding long tip at the inner margin. O.
cygnicollis is in morphology close to O. amberiana
sp. nov., O. pushkari sp. nov., O. storozhenkoi sp.
nov. (Cygnicollis species group) and O. toxopei sp.
nov. (Toxopei species group). O. toxopei sp. nov. is
unique in having widened third antennal segment
from the tip. The neck of O. cygnicollis is signicantly
shorter than in aforementioned species (head
542
Telnov, D. et al. (eds) 2017: Biodiversity, Biogeography and Nature Conservation in Wallacea and New Guinea, III
index in males <1.4, head index in females <1.3,
respectively). The species with similar short neck is
O. pushkari sp. nov. Those species can be separated
by the fourth and fth antennal segments from the
tip morphology.
Dist rib utio n: Only found in the western part of
New Guinea from Nabire over Doberai Peninsula
to Salawati. Sulawesi (Günther 1938a; Steinmann
1970b) is a doubtful record and refers to the syntype
of Tetricodina luteomarginata from Menado (leg.
Wallace). The specimen is lost and up to now no
Ophiotettix has been found on Sulawesi.

Note: Bolívar named the species “bürgersi”. The
correct transliteration of German phonem “ü” in
Latin zoological nomenclature is after the Code
diphthong “ue”. For bürgersi it is thus buergersi,
not burgersi. We use the correct name O. buergersi.
Desc rip tion : Antennal segments brownish to
dark. Only the tip (segment 14+15 in ♀♀, 13+14
in ♂♂) somewhat lighter. Apical segments with
narrow whitish bristles. Three apical segments
(segment 13+14+15 in ♀♀, 12+13+14 in ♂♂)

Differential diagnosis: Together with O.
sanguinea sp. nov. this is the only species with dark
apical antennal segments where the sixth antennal
segment from the tip (segment 10 in ♀♀, 9 in
♂♂) is broadly lamellate and bears a protruding
tip or edge at the inner margin. It differs from O.
sanguinea sp. nov. by the protruding tip of the sixth
antennal segment from the tip (segment 10 in ♀♀,
9 in ♂♂) and the dark postfemora. O. sanguinea
sp. nov. has reddish hind femora.
Dist rib utio n: Only found in the type locality, the

Differential diagnosis: O. lorentzi is one of
the species without pale coloured apical antennal
segments, subapical antennal segments with
lamellate inner margins and a fth antennal
segment from the tip with straight dorsal margin
or it is curved backwards. The dorsal 1/4 of the
length of fourth antennal segment from the tip
runs parallel or convergent towards the tip and
the third antennal segment from tip has no long
prodruding tip. O. lorentzi is near to O. yriveriensis
sp. nov., O. kaitani sp. nov., O. katharinae sp. nov.,
O. karimuiensis sp. nov. and O. quateorum sp.
nov. (Katharinae species group) but differs from
O. yriveriensis sp. nov., O. kaitani sp. nov. and O.
karimuiensis sp. nov. in morphology of the fourth
antennal segment from the tip (segment 12 in ♀♀,
11 in ♂♂), in which the dorsal margin is straight or
with a blunt protruding edge (angle), and without
more or less longer acute tip. It differs from the O
quateorum sp. nov. and O. katharinae sp. nov. in
morphology of the sixth antennal segment from
the tip (segment 10 in ♀♀, 9 in ♂♂), this segment

Desc rip tion : Apical and subapical segments
of the antennae black or brownish. Two apical
segments (segment 14+15 in ♀♀, 13+14 in
♂♂) combined shorter than third apical segment
(segment 13 in ♀♀, 12 in ♂♂). Three apical
segments (segment 13+14+15 in ♀♀, 12+13+14
in ♂♂) together as long as fourth segment from the
tip (segment 12 in ♀♀, 11 in ♂♂). Fifth antennal
segment from the tip (segment 11 in ♀♀, 10 in ♂♂)
with a protruding edge at the inner dorsal margin.
Sixth antennal segment from the tip (segment
10 in ♀♀, 9 in ♂♂) as broad as third antennal
segment from the tip (segment 13 in ♀♀, 12 in

of the fastigium brightened. Median carina a little
bit deeper than the lateral carinae. Visible part
of the abdomen base colour yellowish, with black
patches. Individuals from Wanuma completely

D i f fe r e n t i a l di a g n o s i s : Bolívar (1929) described
O. modesta as a subspecies of O. buergersi. It is
distinguishable from O. buergersi Bolívar, 1929
accurately by some characters: O. buergersi has
shorter neck (head index <1.5, O. modesta >1.8). In
O. modesta the sixth antennal segment from the tip
(tip (segment 10 in ♀♀, 9 in ♂♂) is not widened as
in O. buergersi. In O. modesta hind femora and the
tip of the fastigium is coloured (brightened), while
in O. buergersi it is dark. O. modesta has enough
strong differences (if here assessed variability of
Ophiotettix and difference between the species
are taken into account) from O. buergersi and
we regard it valid, separate species. O. modesta
is near to O. buergersi and O. sanguinea sp. nov.
(they all belong to Buergersi species group). In O.
sanguinea sp. nov. the sixth antennal segment
from the tip (segment 10 in ♀♀, 9 in ♂♂) is
broader than the third antennal segment from the
tip (segment 13 in ♀♀, 12 in ♂♂). In O. modesta it
is as broad as the third antennal segment from the
tip (segment 13 in ♀♀, 12 in ♂♂). O. sanguinea sp.
nov. has a shorter neck (head index <1.8, while in
O. modesta >1.8). O. modesta is one of the species
without pale coloured apical antennal segments,
subapical antennal segments with lamellate inner
margins and fth antennal segment from the tip
with protruded lateral edge. It is protruded visibly
into spine or acute angle. O. modesta is near
to O. imbiana sp. nov., O. rohwedderi sp. nov.,
O. schapinae sp. nov. and O. tenuis sp. nov. (all

(Plates 104-124)
members of Buergersi species group. It differs
from these species (except O. imbiana sp. nov. and
O. rohwedderi sp. nov.) by at vertex. From these
species it differs by three apical segments together
being as long as the fourth segment from the tip
(not longer than).
Dist rib utio n: Northeast of New Guinea from the

Limosina species group, composed of species with
slender antennae without white tips). The species
is unique because of its very long neck.

Desc rip tion : Apical segments of the antennae
pale (third segment from the tip only a little). No
antennal segment with clear tip at the inner margin.
Three apical segments (segment 13+14+15 in ♀♀,
12+13+14 in ♂♂) together as long as or longer
than the fourth segment from the tip (segment
12 in ♀♀, 11 in ♂♂). Outer margin of the fourth
antennal segment from the tip (segment 12 in ♀♀,
11 in ♂♂) lamellate and curved. Apical segments
with narrow whitish bristles. Lateral carinae of the
vertex parallel. Median carina of the vertex lower
than the lateral carinae. Lateral carinae of the
vertex brightened. Pronotum with yellow stripes.
Most of the body coloured. Head, in frontal view,
and ventral margin of the hind femora yellow. The
brightness of the third antennal segment from the
tip (segment 13 in ♀♀, 12 in ♂♂) varies - from a
little at the tip (female from Cyclops Mts.) to more
than a half (specimen from Ifar). The specimens
from Cyclops Mts. (Mt. Lina, Mt. Nomo, leg. L.E.
Cheesman) differs in colouration of the second
and third antennal segment from the tip (segment
13+14 in ♀♀, 12+13 in ♂♂): the third segment has
no pale colouration and the second segment is not
pale at all, but a little brownish to the third segment.
We nd no other differences between the types and
the specimens from Cyclops Mts. Further studies
are needed to answer how diverse are specimens of
this species, and if there is whole species complex
inside with endemic taxa (species or subspecies)
in isolated mountains. Measurements holotype ♂:
pronotum length 7.54 mm, pronotum lobe width
3.25 mm, pronotum height 2.0 mm, hind femur
length 6.63 mm, hind femur width 1.45 mm, vertex
width 0.39 mm, eye width 0.61 mm, antenna length
7.80 mm, head length 4.25 mm, head index 1.38.
Measurements paratype ♀ (allotype), pronotum
length 8.58 mm, pronotum lobe width 3.75 mm,
pronotum height 2.40 mm, hind femur length 7.67
mm, hind femur width 1.70 mm, vertex width 0.39
mm, eye width 0.66 mm, antenna length 8.45 mm,
head length 4.90 mm, head index 1.55. Two other
♀♀ paratypes have head length 4.70 mm and head
index 1.71. 1♀ and 1♂ from Ifar have head length
4.7 (4.3) mm and head index 1.36 (1.48).
Differential diagnosis: Bolívar (1929)
describes O. westwoodi as a subspecies of O.
buergersi Bolívar, 1929. It differs a lot from O.
buergersi by pale apical antennal segments and the
fourth antennal segment from tip (segment 12 in
♀♀, 11 in ♂♂), which does not have distinctly long
tip at the inner margin. O. westwoodi is regarded
as a separate species from O. buergersi, not its
subspecies, but a valid species. As a species with
pale apical antennal segments and at least one
antennal segment with a protruding tip at the inner
margin at the fourth antennal segment from the tip
O. westwoodi is close to O. cheesmanae sp. nov.
and O. meggy sp. nov. (all members of Westwoodi
species group, together with O. fritzpahli sp. nov.).
In O. cheesmanae sp. nov., third antennal segment
from the tip is brightened to the half (in O. westwoodi
only at the tip). The fth antennal segment from the

Deri vati o n omin is: Toponymic. The species is
named after its type locality, Waigeo Island. The
island is also known by the name Amberi, which we
found more suitable for the stem of Latin adjective,
from it consequently making feminine gender
of amberianus, -a –um (rst and second Latin
declension adjective).
Desc rip tion : Antennal segments black. Third to
fth antennal segments from the tip (segments
11+12+13 in ♀♀, 10+11+12 in ♂♂) like a

segments with some narrow whitish bristles. Two
apical segments (segments 14+15 in ♀♀, 13+14
in ♂♂) together shorter than apical third segment
(segment 13 in ♀♀, 12 in ♂♂). Three apical
segments (segments 13+14+15 in ♀♀, 12+13+14

Differential diagnosis: O. amberiana sp. nov.
is one of the species without pale coloured apical
antennal segments, subapical antennal segments
with lamellate inner margins and the third antennal
segment from the tip with a distinctly protruding
long tip at the inner margin. O. amberiana sp. nov.
is near to O. cygnicollis sp. nov., O. pushkari sp. nov.,
O. storozhenkoi sp. nov. (Cygnicollis species group)
and O. toxopei sp. nov. (Toxopei species group). O.
toxopei sp. nov. is unique in having widened third
antennal segment from the tip. O. amberiana sp.
nov. differs from other species of the Cygnicollis
species group in morphology of the sixth antennal
segment, which is as broad as the third antennal
segment from the tip and not smaller (>0.18 mm).
Dist rib utio n: Only found on Mount Nok in the

in ♀♀, 12+13+14 in ♂♂) together longer than
fourth segment from the tip (segment 12 in ♀♀,
11 in ♂♂). Fourth antennal segment from the tip
(segment 12 in ♀♀, 11 in ♂♂) narrow, without
protruding edge at the inner dorsal margin. Fifth
antennal segment from the tip (segment 11 in
♀♀, 10 in ♂♂) with straight dorsal margin. Sixth
antennal segment from the tip (segment 10 in
♀♀, 9 in ♂♂) narrower than the third antennal
segment from the tip (segment 13 in ♀♀, 12 in
♂♂). Lateral carinae of the vertex convergent. Tip
of the fastigium dark. Vertex, in frontal view, at,
median carina of the vertex as high as the lateral
carinae. Pronotum with yellow lateral parts and
infrascapular area. Visible part of the abdomen
predominantly yellow. Hind femur partially yellow.
Measurements holotype ♀: pronotum length 9.62
mm, pronotum lobe width 4.03 mm, pronotum
height 2.50 mm, hind femur length 8.97 mm, hind
femur width 1.60 mm, vertex width 0.49 mm, eye
width 0.64 mm, antenna length 10.14 mm, head
length 5.20 mm, head index 2.23.
Differential diagnosis: O. bewana sp. nov. is
one of the species with very narrow margins of the
antennal segments and no protruding tip at the
inner margin (members of the Limosina species
group). Together with O. mountnokensis sp. nov.
and O. scolopax (also members of Limosina species
group), they are the only species of this group (and
of the genus) with convergent lateral carina. It is
easily separated from O. scolopax by the shorter
neck and from O. mountnokensis sp. nov. by the
dark tip of the fastigium.

Deri vati o nom inis : The specic epithet is a
combination of two Latin words, one adjective and a
noun - ‘brevi-’ being borrowed from Third declension
adjective ‘brevis, -e’, meaning short, while ‘collis’
is ablative plural of the neuter gender second (-us)
declension noun ‘collum, -i, n.’ meaning neck.
Whole epithet thus means ‘with short neck’ and
is plural noun in ablative. The species is named in
such way because of the short head.
Desc rip tion : Apical and subapical segments of
the antennae black, other segments brownish. Two
apical segments (segments 14+15 in ♀♀, 13+14 in
♂♂) together longer than the third apical segment
(segment 13 in ♀♀, 12 in ♂♂). Three apical
segments (segments 13+14+15 in ♀♀, 12+13+14
in ♂♂) together longer than fourth segment from
the tip (segment 12 in ♀♀, 11 in ♂♂). Only fourth
antennal segment from the tip (segment 12 in ♀♀,
11 in ♂♂) with a protruding tip at the inner dorsal
margin. This segment is widened towards the tip.
Inner edge of the dorsal margin of the fth antennal
segment from the tip (segment 11 in ♀♀, 10 in ♂♂)
runs backwards. Lateral carinae of the vertex run
parallel. Tip of the fastigium brightened. Median
carina, in frontal view, deeper than the lateral
carinae. Pronotum with yellow stripes. Visible part
of the abdomen partially yellow. Measurements

Differential diagnosis: O. brevicollis sp. nov.
is one of the species without pale coloured apical
antennal segments, subapical antennal segments
with lamellate inner margins and the upper edge of
the fth antennal segment from the tip is straight
or curved backwards. The fourth antennal segment
from the tip is widened in its whole length towards
the tip. There are three other species with similar
characters: O. roesleri sp. nov. (Brevicollis species
group), O. stallei sp. nov. (Stallei species groups)
and O. subbrevicollis sp. nov. (Brevicollis species
group). All the mentioned species are very small
in body size. O. brevicollis sp. nov. differs from O.
stallei sp. nov. and O. subbrevicollis sp. nov. by
the sixth antennal segment from the tip which is
not widened with a recognizable edge. From O.
roesleri sp. nov. it differs by the brightened tip of
the fastigium and even smaller size.

Deri vati o n omin is: Patronymic. The species is
named after Lucy Evelyn Cheesman (1882-1969).
This lovely British entomologist, anthropologist,
polyglot, adventurer and heroine spent 12 years
(during the 1920s and 1930s) travelling alone
(without European colleagues) and investigating
nature in the New Guinean Region, meeting
local tribes and learning local languages. She
was known among local tribes as ‘the Woman
Who Walks’ and our favourite - ‘the Lady of the
Mountains’. She collected between 1924 and
1952 in eight expeditions in the South Pacic
over 70000 specimens. We are honoured to work
on the material she collected during her peculiar
expeditions, and happy to dedicate this species to
her. The specic epithet represents the genitive
case of the rst declension (a- declension, de facto
only for feminine gender nouns) Latinized form of
Lucy’s surname ‘Cheesmana, ae, f.’ We decided
to name this species from the high, inaccessible
mountains of Yapen island In her honour - let it
be an adventure to nd the Giraffehopper of Lucy
Evelyn again.
Desc rip tion : Apical segments of the antennae
pale (third segment from the tip to the half of its
length). Two apical segments (segments 14+15 in
♀♀, 13+14 in ♂♂) together shorter than the third
apical segment (segment 13 in ♀♀, 12 in ♂♂).
Three apical segments (segment 13+14+15 in ♀♀,
12+13+14 in ♂♂) together longer than the fourth
segment from the tip (segments 12 in ♀♀, 11 in
♂♂). Only fourth antennal segment from the tip
(segment 12 in ♀♀, 11 in ♂♂) with a protruding
tip at the inner dorsal margin. Outer margin of this
antennal segment lamellate and curved. Sixth
antennal segment from the tip (segment 10 in
♀♀, 9 in ♂♂) broader than third antennal segment
from the tip (segment 13 in ♀♀, 12 in ♂♂).
Lateral carinae of the vertex run parallel. Tip of
the fastigium dark. Median carina of the vertex, in
frontal view, deeper than lateral carinae. Pronotum
with brightened stripes. Visible part of the abdomen
dark. Hind femur with one brightened patch at the
dorsal margin close to the basis. Measurements
holotype ♀: pronotum length 9.75 mm, pronotum
lobe width 4.15 mm, pronotum height 2.20 mm,
hind femur length 8.71 mm, hind femur width 1.75
mm, vertex width 0.43 mm, eye width 0.74 mm,
antenna length 9.10 mm, head length 5.04 mm,
head index 1.77.
Differential diagnosis: As a species with
pale apical antennal segments and at least one
antennal segment with a protruding tip at the inner
margin at the fourth antennal segment from the tip
O. cheesmanae sp. nov. is morphologically similar
to O. westwoodi stat. rev. and O. meggy sp. nov.
(together with this species belong to Westwoodi
species group, including also O. fritzpahli sp. nov.).
In O. cheesmanae sp. nov. the third antennal
segment from the tip (segment 13 in ♀♀, 12 in
♂m) is brightened to the half (in O. westwoodi stat.
rev. only at the tip). The fth antennal segment from
the tip (segment 11 in ♀♀, 10 in ♂♂) in O. meggy
bears a protruding edge at the inner dorsal margin
(in O. cheesmanae sp. nov. not) and has distinct
silver bristles on the apical antennal segments (O.
cheesmanae sp. nov. does not have silver bristles).

Deri vat io n omi nis : The species is named for the
attened pronotum. The specic epithet is Latin rst
and second declension adjective, ‘depressus, -a,
-um’ in feminine gender, which is in fact participle
of the passive voice of perfect tense of the verb
‘deprimo, deprimere, depressi, depressum’ -
meaning to press down.
Desc rip tion : Apical segments of the antennae
brownish, other segments dark. No antennal
segment broadly lamellate. Two apical segments
(segments 14+15 in ♀♀, 13+14 in ♂♂) together
shorter than third apical segment (segment 13 in
♀♀, 12 in ♂♂). Three apical segments (segments
13+14+15 in ♀♀, 12+13+14 in ♂♂) together as
long as the fourth segment from the tip (segment
12 in ♀♀, 11 in ♂♂). Fourth antennal segment
from the tip (segment 12 in ♀♀, 11 in ♂♂) narrow
and elongate. Sixth antennal segment from the

Differential diagnosis: O. depressa sp. nov. is
one of the species with dark antennae and antennal
segments with small margins but not lamellate or
broadened. The other species of this group are:
O. scolopax Bolívar, 1929, O. bewana sp. nov., O.
bomberaiensis sp. nov., O. liforma sp. nov., O. luce
sp. nov., O. mountnokensis sp. nov. and O. projecta
sp. nov. (listed here are members of Limosina
species group, without O. limosina, species with
rounded all the segments). O. depressa sp. nov.
differs from O. scolopax in head index (>3 in O.
scolopax) and in brightened tip of the fastigium.
Also O. liforma sp. nov. and O. bewana sp. nov.
have dark tip of the fastigum. O. depressa sp. nov.
differs from O. luce sp. nov. and O. projecta sp. nov.
in the fth antennal segment from the tip (segment
11 in ♀♀, 10 in ♂♂) morphology - straight or curved
backwards. The fourth antennal segment from the
tip is in O. luce sp. nov. is widened towards the tip.
O. projecta sp. nov. has fastigium protruded in front
of the eyes (in lateral view). In O. bomberaiensis
sp. nov. the fourth antennal segment from the tip
(segment 12 in ♀♀, 11 in ♂♂) is longer than the
fth antennal segment from the tip. In O. bewana
sp. nov. and O. mountnokensis sp. nov. lateral
carinae of the vertex are convergent to the tip, not
parallel.

N ot e : Specimens from the Cyclops Mountains seem
to be different species closely related in morphology
to O. liforma sp. nov. They have shorter antennae
and apical segments differ in morphology. It is not
possible here to describe those specimens as a
new species until longer series from O. liforma sp.
nov. and from the Cyclops Mountains are gathered.

Deri vati o nom ini s : The specic epithet is rst
and second. Latin declension adjective (liformus,
-a, -um) derived from the third Latin declension
adjective (liformis, -e). The species bears this
epithet because of the liform slender and elegant
antennae.
Desc rip tion : Antennal segments from dark
(apical segments) to brownish (basal segments).
No antennal segment broadened lamellate. Two
apical segments (segments 14+15 in ♀♀, 13+14

(segment 13 in ♀♀, 12 in ♂♂). Three apical
segments (segments 13+14+15 in ♀♀, 12+13+14
in ♂♂) together as long as fourth segment from the
tip (segment 12 in ♀♀, 11 in ♂♂). Fourth antennal
segment from the tip (segment 12 in ♀♀, 11 in
♂♂) narrow and elongated. Sixth antennal segment
from the tip (segment 10 in ♀♀, 9 in ♂♂) as broad
as third antennal segment from the tip (segment
13 in ♀♀, 12 in ♂♂). Lateral carinae of the vertex
run parallel. Tip of the fastigium dark with an
exception (paratype 17/18 has bright fastigium).
Median carina of the vertex as high as lateral
carinae. Pronotum with broad yellow stripes. Visible
part of the abdomen yellow or partially yellow.
Dorsal margins of all legs yellow. Measurements

Differential diagnosis: O. liforma sp. nov.
is one of the species with dark antennae and
antennal segments with small margins, not
lamellate or broadened. Other species of this group
are: O. scolopax Bolívar, 1929, O. bewana sp. nov.,
O. bomberaiensis sp. nov., O. depressa sp. nov.,
O. luce sp. nov., O. mountnokensis sp. nov. and
O. projecta sp. nov. (all listed species, including
O. liforma sp. nov. are members of the Limosina
species group, characteristic in slender antennae).
Together with O. scolopax and O. bewana sp. nov.,
O. liforma sp. nov. is the only species with dark tip
of the fastigium. O. liforma sp. nov. differs from
O. scolopax in head index (>3 in O. scolopax) and
from O. bewana by the parallel lateral carinae of the
vertex. As in O. projecta sp. nov., in O. liforma two
apical segments (segments 14+15 in ♀♀, 13+14
in ♂♂) are together as long as third apical segment
(segment 13 in ♀♀, 12 in ♂♂). O. projecta sp. nov.
differs by its fastigium protruded in front of the eyes
(in lateral view).

Deri vati o n omin is: Toponymic. The species
is named after the region of its type locality - the
adjective was derived from ‘Fly’ + ‘River+’ + ‘-ensis’.
The specic epithet is third Latin declension
adjective in feminine gender (yriveriensis, -e).
Description: Antennal segments dark. Third to
sixth antennal segments (segments 10+11+12+13
in ♀♀, 9+10+11+12 in ♂♂) broadened lamellate.
Two apical segments (segment 14+15 in ♀♀,
13+14 in ♂♂) together shorter than third apical
segment (segment 13 in ♀♀, 12 in ♂♂). Three apical
segments (segments 13+14+15 in ♀♀, 12+13+14
in ♂♂) together as long as fourth segment from the
tip (segment 12 in ♀♀, 11 in ♂♂). Outer margin of
fourth antennal segment from the tip (segment 12
in ♀♀, 11 in ♂♂) lamellate and curved, with a tip
at the inner dorsal margin. The dorsal 1/4 of this
segment convergent towards the tip. Sixth antennal
segment from the tip (segment 10 in ♀♀, 9 in ♂♂)
broader than third antennal segment from the tip
(segment 13 in ♀♀, 12 in ♂♂). Apical segments
with narrow whitish bristles. Lateral carinae of the
vertex run parallel. Tip of the fastigium brightened.
Median carina of the vertex, in frontal view, deeper
than lateral carinae. Pronotum with yellow stripes.
Visible part of the abdomen partially yellow. Hind
femora predominantly yellow. Apical segments of a
specimen from Matkomrae village lighter brownish
and narrower, neck somewhat narrower and more
curved. Measurements are within the variation of
O. yriveriensis sp. nov. We assign this specimen to
O. yriveriensis sp. nov. More specimens from this

Differential diagnosis: O. yriveriensis sp. nov.
is one of the species without pale coloured apical
antennal segments, subapical antennal segments
with lamellate inner margins and fth antennal
segment from the tip with straight or backwards
curved dorsal margin. The dorsal 1/4 of the fourth
antennal segment from the tip length parallel or
convergent towards the tip and third antennal
segment from the tip does not bear protruded tip.
O. yriveriensis sp. nov. is close in morphology to
O. lorentzi Bolívar, 1929 (Lorentzi species group),
O. kaitani sp. nov., O. katharinae sp. nov., O.
karimuiensis sp. nov. and O. quateorum sp. nov.
(Katharinae species group), but differs from those
species by three apical antennal segments, which
are together as long as fourth antennal segment
from the tip.

Deri vati o no min is: Patronymic. The specic
epithet is genitive case of the second Latin
declension (-us declension) masculine noun
derived from combination of name and surname
(Fritzpahlus, -i, m.) The species is dedicated to late
Fritz Pahl, a very good friend of Tumbrincks’ family,
who died in his 88th year in 2016.
Desc rip tion : Apical segments of the antennae
pale (third segment from the tip pale in more than
half of its length and fourth segment from the tip
only a little bit). No antennal segment with a clear
tip at the inner margin, but antennal segments
third to sixth from the tip (segments 10+11+12+13
in ♀♀, 9+10+11+12 in ♂♂) broadened and
lamellate. Two apical segments (segments 14+15
in ♀♀, 13+14 in ♂♂) together as long third apical
segment (segment 13 in ♀♀, 12 in ♂♂). Three
apical segments (segments 13+14+15 in ♀♀,
12+13+14 in ♂♂) together longer than fourth
segment from the tip (segment 12 in ♀♀, 11 in
♂♂). Outer margin of fourth antennal segment from
the tip (segment 12 in ♀♀, 11 in ♂♂) lamellate
and curved, with somewhat protruded edge at the
inner dorsal margin. Sixth antennal segment from
the tip (segment 10 in ♀♀, 9 in ♂♂) widened, with
a recognizable edge, broader than third antennal
segment from the tip (segment 13 in ♀♀, 12 in
♂♂). Apical segments with narrow whitish bristles.
Lateral carinae of the vertex run parallel. Tip of the
fastigium brightened. Median carina of the vertex, in
frontal view, deeper than lateral carinae. Pronotum
with yellow stripes. Hind femora and visible part
of the abdomen partially yellow. Measurements

Differential diagnosis: As a species with pale
apical antennal segments and no antennal segment
with a protruding tip at the inner margin O. fritzpahli
sp. nov. (we tentatively put this species within
Westwoodi species group but it shows intermediate
characters between this group and Pulcherrima
species group) is near to O. pulcherrima sp. nov.
and O. rebrinae sp. nov. (both members of the
Pulcherrima species group). It differs from these
species easily deep vertex and dark tip of the

Deri vati o nom ini s: The specic epithet is second
(-us) Latin declension noun in masculine gender,
derived from the name and surname combination
(Hannsscholtenus, -i, m.) The species is dedicated
to Hans Scholten, the president of Naturschutzbund
Deutschland (NABU) from 1984 - 1988.
Desc rip tion : Antennal segments of dark
brownish. No antennal segments lamellate. Two
apical segments (segments 14+15 in ♀♀, 13+14
in ♂♂) together as long as third apical segment
(segment 13 in ♀♀, 12 in ♂♂). Three apical
segments (segment 13+14+15 in ♀♀, 12+13+14
in ♂♂) together longer than fourth segment from
the tip (segment 12 in ♀♀, 11 in ♂♂). Fourth
antennal segment from the tip (segment 12 in ♀♀,
11 in ♂♂) narrow, widened towards the tip and with
little bit protruded edge at the inner dorsal margin.
Sixth antennal segment from the tip (segment 10 in
♀♀, 9 in ♂♂) as broad as third antennal segment
from the tip (segment 13 in ♀♀, 12 in ♂♂). Apical
segments with narrow whitish bristles. Lateral
carinae of the vertex run parallel. Lateral carinae
of the vertex and median carina brightened. Vertex,
in frontal view, attened, median carina as high as
lateral carinae. Pronotum with yellow lateral parts
and infrascapular area. Visible part of the abdomen
predominant yellow. Hind femur partially yellow.
