INTRODUCTION
The genus Callimetopus belongs to the sub-
family Lamiinae and tribe Pteropliini. It is one of
the more complicated tribe of Cerambycidae.
Many genera of Pteropliini are still poorly stud-
ied and they need taxonomic revisions. In recent
years, Callimetopus has been intensively stud-
ied. Many new species has been described by
several authors: Vives (2012, 2015, 2017), dela
Cruz & Adorada (2012) and Barševskis (2015a,
2015b, 2015c, 2016a, 2016b, 2018a). One species
was synonymized by Chemin & Vives (2017).
Barševskis (2018b) published faunistic records
of twenty four species of Callimetopus of the
Oriental Region and provided new records of
eleven species which are collected for the first
time after their descriptions.

The genus Callimetopus distributed in the Ori-
ental region and represented by 49 species: 44
species are known from the Philippine archi-
pelago, two species - from the Moluccan archi-
pelago, one species from the Moluccan archi-
pelago and peninsular Malaysia, one species
from Borneo and one species from Sulawesi and
peninsular Malaysia.
During the study of the material on the genus
Callimetopus Blanchard, 1853 (Coleoptera:
Cerambycidae) at the Daugavpils University Bee-
tle Collection (DUBC) the author has been dis-
covered two new species of this genus, the de-
scriptions of which are provided in this article.

MATERIAL AND METHODS
The studied material is deposited in the beetles
collection of Daugavpils University, Institute of
Life Sciences and Technology, Coleopterological
Research Centre (DUBC - Ilgas, Daugavpils Distr.,
Latvia).
The laboratory research and measurements have
been performed using Nikon AZ100, Nikon
SMZ745T and Zeiss Stereo Lumar V12 digital
stereomicroscopes, NIS-Elements 6D software.
The habitus photograph was obtained with a dig-
ital camera Canon EOS 6D with Canon MP-E 65
mm macro lens, using Helicon Focus auto mon-
tage and subsequently was edited with
Photoshop. All measurements are given in
millimeters.

cence; antennomeres 3 and 4 elongated, covered
with dense white pubescence basally, with dark

maining antennomeres black, with dense, fine

punctures between it and between coarse punc-
tures with very fine micropunctation. Basal an-
gles of pronotum acute. Lateral parts of pronotum
with pair of prominent hump. Scutellum rounded
apically, with pubescence and very fine
micropunctures.
Elytra black, shiny, covered with dense yellow-
brown pubescence in basal and apical portions,
with black, often irregular small spots between
them, with wide band of white pubescence in the
middle portion. White, transverse band (more
distinct in lateral sides) separated on both sides
from yellow - brown portions by smooth area
with very sparse pubescence. Basal portions of
elytra with more coarse punctures than that
apically. Each elytron along stria with row of
black spots. Apex of elytra subtruncate, very
slightly concave, with inner sharp projection and
visible short triangular outer projections.
Ventral side of body in general with very dense
yellow-brown pubescence and with black sparse
punctures between it.

cence and black punctures. Forelegs distinctly

longer than middle and hind legs. Sides of middle
tibia with rows of dense setae.
Differntial diagnosis. Basedon the similar shape
of elytra, the new species is similar to C. capito
(Pascoe, 1865) (Fig. 2), but differs from this spe-
cies by following characters: 1) new species with
basal portions of antennomeres 3 and 4 with
densely covered white pubescence (only basal
portion of antennomere 3 of C. capito cowered
with dense white pubescence); 2) elytra of the
new species along the suture with a row of black
spots (elytra of C. capito along suture with three
or more rows of black spots); 3) basal and apical
portions of elytra of new species covered with
yellow - brown pubescence, and in the middle
with wide band of white pubescence separated
on both sides from yellow-brown portions with
smoth area (coloration of elytra of C. capito is
different: wide white transverse band is inter-
rupted, but separation from yellow - brown por-
tion of elytra not so distinct as that in C.
bumbierisi sp. n.).

with three elongate keels: median keel between
eyes stretching from levels of posterior margin
of eyes to apical portion of head; dorsolateral
sides of head with two keels stretching from base
of antennae to base of mandibles, curved later-
ally and forming deep furrow. Head covered with
dense yellow-brown pubescence and coarse,
sparse punctation. Eyes bilobate, not protruded.

cence and several setiferous punctures and dark
setae. Clypeus transverse, narrow, yellow-red,
smooth, without pubescence. Labrum brown,
slightly bilobate in apical margin, weakly con-

cence and several small spots of white pubes-
cence; basal part of antennomere 4 covered with
dense white pubescence, apical part of this seg-
ment black; inner side of antennomere 3 with row
of dark setae; antennomere 5 black, shiny, with
very sparse dark pubescence; remaining
antennomeres black, with dense, fine and dark

micropunctution between coarse punctures. Ba-
sal angles of pronotum acute, triangular, sharp.

with small spots of dense yellow-brown pubes-
cence. Punctures at the base of elytra more
coarse as below. Behind the middle elytra with
thin wave-shaped line of yellow-brown pubes-
cence. Apex of elytra truncate, without sharp pro-
jections.

between it.
Legs short and robust, black, covered with dense
yellow-brown pubescence and black puntures.
The forelegs longer than middle legs and hind
legs. Lateral sides of tibia of middle legs with
rows of dense yellow-brown setae.
Differential diagnosis. Based on the similar
shape of elytra, the new species is similar to
Callimetopus mindorensis dela Cruz, Adorada,
2012 (Fig. 4), but differs by following characters:
1) apical margins of elytra of a new species trun-
cate, without sharp projections (apical margins
of elytra of C. mindorensis subtruncate, with two
visible projections); 2) elytra of a new species
covered with small irregular spots of yellow-
brown pubescence (elytra of C. mindorensis cov-
ered wits sparse or very sparse small spots of

white pubescence, and white and yellow-brown
pubescence in apical portion).
Etymology. Toponymic. The name of species is
derived from the name of island, where it was
collected: Marinduque (Philippines) –
marinduquensis.
