INTRODUCTION
The genus Calidiopsis Heller, 1913 (Cole-
optera: Celeuthetini) currently contains six
species: C. speciosa Heller, 1913 (Minda-
nao, Zamboanga), C. lineata Schultze, 1918
(Mindanao, Zamboanga), C. affinis
Schultze, 1920 (Mindanao, Zamboanga), C.
granosa Heller, 1923 (Basilan Island) and
recently described C. bilineatus Rukmane-
Bārbale, 2020 (Central Mindanao) and C.
waoensis Rukmane-Bārbale, 2020 (Minda-
nao, Wao) (Heller, 1913, 1923; Schultze,
1918, 1920; Rukmane-Bārbale, 2020).
Till now, C. granosa Heller, 1923 was the
only species of the genus present on Basilan
Island, with no records outside the Basilan.
The new coleopterological material from
Zamboanga revealed, that curculionid fauna
of the region also contain C. granosa Hel-
ler, 1923. Together with new distribution
record, supplemented description of mor-
phological characters and appearance is
presented in this short communication with
aim to extend the knowledge of the genus
Calidiopsis Heller, 1913.
MATERIAL AND METHODS
The study was based on specimens deposit-
ed at the Daugavpils University Beetle Col-
lection, Daugavpils, Latvia (DUBC) and
Senkenberg Natural History Collections,
Dresden, Germany (MTD).
The laboratory research and measurements
have been carried out using Nikon SMZ
745T and NIS-Elements 6D software. The
illustrations were made using digital camera
Canon EOS 6D with Canon MP-E 65mm
macro lens, using stack shot system and
Helicon Focus auto montage, subsequently
was edited using Photoshop.

Original description: ‘’Calidiopsis

tro dorso dense albido, prothorace ely-
trisque ubique, illosqamulis minutissimis

Notes on types: The original description
was based on two specimens now deposited
in MTD (Dresden, Germany) both from
Island of Basilan. The label data of Holo-
type include five labels: ‘’1922 / 6’’ (yel-
low rectangular label); ‘’Island of / Basilan
/ Baker’’ (brown rectangular label);
‘’7314’’ (brown rectangular label); ‘’C.
granosa / Typus’’ (red rectangular label);

den’’ (white rectangular label) (Fig. 3).

External morphological features: Male:
Body black, with markings of single light
scales on rostrum dorsally and elytra; fe-
mur, tibia and tarsus bare black or marked
with single, light scales of round shape;
antennae bare or marked with single, light
scales of round shape; Rostrum smooth,
widened to apex, with light pubescence to
longer, light hairs along impressions; deep
medial longitudinal groove dorsally; two
deep impressions at base near the eyes; two
large impressions along antennal scape.
Eyes large, strongly bulging from the out-
line of the head, two times as wide as fore-
head each. Antennae with scape slightly
longer than funicle and club, scape with
long setae on all length, widened to apex;
Prothorax strongly rugose, in dorsal con-
tour widest just before the middle, in lateral
contour curved along apical 1/2; without
markings of light scales; Elytra ellipsoidal,
strongly granulated, with expressed longi-
tudinal intervals; in dorsal contour widest
just at the middle, in lateral contour gradu-
ally rounded, peak just at the middle; apical
half of elytra with single setae; rare single
light scales of round shape mingled on all
length, density of scales vary along speci-
mens. Dorsal habitus as showed in Fig. 1A.
Aedegal body as showed in Fig. 2.
Female: Bigger, prothorax and elytra more
strongly rounded, hairs on legs (femur, tib-
ia, tarsus), antenae and elytra longer, dense.
Otherwise as in males. Dorsal habitus as
shown in Fig. 1B.
