Figs 20 View Figs 20–21 , 25–27 View Figs 22–29 .
MATERIAL. Holotype, ♂ (partially obliterated, the head is missing) “C Sulawesi Prov., 50m, 6km E Tambarana, 120.28.06E 1.11.15 S, Bolm lgt. 9.–11July 1999 ” ( SMNS). Paratypes: 9♀♀ “C Sulawesi Prov., 50m, 6km E Tambarana, 120.28.06E 1.11.15 S, Bolm lgt. 9.–11July 1999 ” ( SMNS; cMG — 2♀♀) .
DESCRIPTION. The only known male (holotype) lacks the head (it was apparently lost during storage or primary mounting), and the description is therefore based on the female paratype ( Fig. 20 View Figs 20–21 ) that has colouration and microsculpture matching those on the comparable body parts of the holotype. Length about 2.7 mm. Overall colouration brown. Entirely brown, head slightly darker than pronotum and elytra; legs and antennae light brown. Integument slightly shining, body with short, light-coloured hairs.
Head transverse, with a wide base, ratio of its length (from posterior margin of head to anterior margin of clypeus) to maximum width about 21:32. Neck constriction prominent. Eyes large, convex, temples well-developed, round, eye diameter in dorsal view about 2.0 times as long as temple length. Head widest across eyes ( Fig. 20 View Figs 20–21 ). Head surface with very delicate, extremely fine and dense punctation. Puncture diameter about 5 times as small as eye facet. Distances between punctures slightly smaller than their diameter, interspaces smooth, slightly shining. Antennae long, with length of all antennal segments noticeably or significantly exceeding their width ( Fig. 20 View Figs 20–21 ).
Pronotum widest about 2/3 its length from base, then narrowed. Lateral margins smoothly rounded ( Fig. 20 View Figs 20–21 ). Ratio of pronotum length to its maximum width about 27:34 (25: 33 in holotype). Surface of pronotum with very delicate, extremely fine and dense punctation. Puncture diameter about 5 times as small as eye facet. Distances between punctures slightly smaller than their diameter, interspaces smooth, slightly shining. Pronotal disc with 1 weak oval depression along midline at apex and 2 pairs of rather well-developed, symmetrical depressions: 1 pair of widely crescent-shaped depressions separated by low medial ridge, near disc base and 1 pair of longitudinal, bean-shaped depressions, with slightly diverging apices, on either side of midline in central part of disc ( Fig. 20 View Figs 20–21 ).
Ratio of length of elytra to their combined length about 43:48 (43: 44 in holotype). Scutellum with weak, longitudinal depressions ( Fig. 20 View Figs 20–21 ). Surface of elytra with very delicate, fine and dense punctation. Puncture diameter about 4 times as small as eye facet. Distances between punctures approximately equal to their diameter, interspaces smooth, slightly shining.
Abdomen delicately shagreened.
Aedeagus of characteristic structure ( Figs 25–26 View Figs 22–29 ).
Female. Sexual dimorphism absent, female morphologically similar to male.
Spermatheca of characteristic structure ( Fig. 27 View Figs 22–29 ).
COMPARATIVE REMARKS. The new species is similar in colouration, size, body morphology and integument microsculpture to Carpelimus (Bucephalinus) assingi Gildenkov, 2014 , but differs in having a finer punctation on the elytra and in the structure of the spermatheca and can be clearly distinguished by the structure ( Figs 25–26 View Figs 22–29 ) of the aedeagus [ Gildenkov, 2014b: 186, Fig. 1 View Figs 1–3 : 1–2].
