INTRODUCTION
The Philippines is one of the most mega-biodi-
verse places in the world (Catibog-Sinha &
Heaney, 2006; Heaney & Regalado, 1998), with
many endemic species. At the same time, the Phi-
lippines is one of the world’s biodiversity hotspots,
where biodiversity is rapidly declining. There-
fore, the study of the fauna and flora of the Philip-
pines is a very important task. The authors have
been conducting joint studies of beetle fauna in
the Philippines for many years. This article is
dedicated to the study of the fauna of the long-
horned beetle genus Callimetopus Blanchard,
1853 (Coleoptera: Cerambycidae).
The genus Callimetopus belongs to the subfamily
Lamiinae Latreille, 1825 and the tribe Pteropliini
Thomson, 1861. In the world fauna, the genus
Callimetopus is represented by 50 species, distri-
buted in three countries of the Oriental Region:
44 species in the Philippines, 4 species in Indo-
nesia, and 2 species in Indonesia & Malaysia.
Recently, several Callimetopus species had been
described by Vives (2012b, 2015, 2017), dela
Cruz & Adorada (2012), Barevskis (2015a,
134
Barevskis A., Cabras A.A., Medina M.N.
2015b, 2015c, 2016a, 2016b, 2018a, 2018b, 2018c,
2019, 2020) with one synonymy by Chemin &
Vives (2017). Most of the species are local ende-
mics with a narrow distribution range. In the Phi-
lippines, the largest diversity of the species are
known from Luzon (22 species), followed by
Mindanao (9 species), Panay (5 species), Samar
(4 species), Negros (3 species), Leyte, Palawan,
Sibuyan (2 species each), Basilan, Dinagat,
Marinduque, Mindoro, Siargao (1 species each),
while, two species are without specific geographic
reference in the Philippines. (Barevskis 2016,
corrected; Tavakilian, Chevillotte 2022, Roguet
2004–2021).
For the past fiveyears, the Philippine long-horned
beetles (Coleoptera: Cerambycidae) has been
actively studied. Every year, many new species
have been described (Barevskis 2021; Barev-
skis, Cabras 2021; Botero, Vives 2021; Medina
et al. 2021, 2022; Barevska, Barevskis 2020;
Barevskis, SaulÓte 2020; Vitali, 2017, Kuleshov,
2017,Vives 2012a, 2012b, 2017, 2020, 2022; etc.).
This paper presents the fifth species of Callime-
topus from Panay Island. Four species were
previously known from this island: C. cordifer
Heller, 1924, C. griseus Breuning 1960; C. kalninsi
Barevskis 2019; C. panayanus (Schultze, 1920).
Detailed description and photographic reference
of other species in the Philippines is also provided.
MATERIAL AND METHODS
The type specimens of the new species are depo-
sited in the collection of the Daugavpils Univer-
sity, Coleopterological Research Centre, Ilgas,
Daugavpils District, Latvia (DUBC). All speci-
mens have been collected in the Philippines by
local collectors.
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 EOS6Dwith Canon MP-E
65 mm macro lens, using Helicon Focus auto
montage and subsequently was edited with Photo-
shop. All measurements are given in millimeters.

General distribution: Philippines: Panay island.
Description. Body elongate, black, lustrous, sur-
face with small spots of white and yellow-brown
pubescence (Fig. 1). Body length: 18.2 mm, maxi-
mal width of elytra: 6.2 mm.
Head flat, wide, with almost parallel sides, with

scence. Surface of head with sparse and coarse
punctuation and covered with small, in some
places merged spots of yellow-brovn pubescence.
Middle portion of head with a flat smooth band
without pubescence, with a very thin longitudinal
line in the middle.
Labrum dark brown, pubescent, with punctures,
covered with dark pubescence except small por-
tions on lateral parts near frontal edge, covered
with yellow pubescence. At frontal edge labrum
covered with long hairs. Clypeus dark-brown, nar-
row, transverse, shiny. Mandible shiny, massive,
relatively wide and sharp, with very fine, sparse
wrinkles and punctures in basal part, covered with

meres with dense white pubescence at the basal

Differential diagnosis. The new species by shape
of draving of surface similar to Callimetopus
cabrasae Barevskis, 2018 (Fig. 2) from Min-

danao, but differs from it in unicolor black legs,
black prothorax, coarser punctation and wrin-
kling of the pronotum, dark mouthparts and less
coarsely punctate elytra. The new species in colo-
ration of surface similar also to Callimetopus
kalninsi Barevskis, 2018 (Fig. 3), but differs
with the absence of denticles on the sides of the
pronotum and extensions at the apex of the elytra,
the body surface is not so flat, the punctation of
the surface is different and other features.

Etymology. The specific epithet is the Latinized
adjective derived from the name of the island,
where the species was collected. [Panay = panay-
ensis].
