Paratypes : 2♂♂ , 5♀♀ , 3 ex. “S Sulawesi Prov. , 400 m 20km NE Sabbang 2.28.56 S 120.12.00 E 5.–7.Jul 2001 , Bolm lgt.” ( SMNS ; cMG — 1♂ , 1 ex. ) . DESCRIPTION ( holotype ). Length 3.0 mm. Entirely black; legs and antennae dark 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 25:38. Neck constriction prominent. Eyes large, convex, occupying almost entire lateral sides of head, temples barely developed ( Fig. 6 ). Head surface with very delicate, extremely fine and dense punctation. Puncture diameter more than 5 times as small as eye facet. Distances between punctures about equal to their diameter, interspaces slightly shagreened, separate punctures in some places difficult to distinguish. Antennae rather long, with lengths of all antennal segments exceeding their width ( Fig. 6 ). Pronotum widest about 2/3 its length from base, then narrowed. Lateral margins straight from base, then smoothly rounded ( Fig. 6 ). Ratio of pronotum length to its maximum width about 32:40. Surface of pronotum with delicate, extremely fine and dense punctation; punctation similar to that on head, but more distinct. Puncture diameter more than 5 times as small as eye facet. Distances between punctures about equal to their diameter, interspaces smooth, slightly shining. Pronotal disc with 1 barely noticeable narrow unpaired depression along midline at apex and 2 pairs of symmetrical depressions: 1 pair near disc base, merging across midline to form a rather deep diamond-shaped pit and 1 pair of rather weak, longitudinal, bean-shaped depressions, with slightly diverging apices, on either side of midline in central part of disc ( Fig. 6 ). Ratio of length of elytra to their combined width about 53:56. Scutellum with weak, round depressions ( Fig. 6 ). Surface of elytra with delicate, fine and dense punctation. Puncture diameter about 4 times as small as eye diameter. Distances between punctures about equal to their diameter, interspaces smooth, slightly shining. Abdomen delicately shagreened. Aedeagus of characteristic structure ( Figs 22–23 ). Female. Sexual dimorphism absent, female morphologically similar to male. Figs 20–21. Carpelimus spp. , dorsal view: 20 — Carpelimus ( Bucephalinus ) tanbaranensis , sp.n. , paratype, female; 21 — Carpelimus ( Bucephalinus ) solumus , sp.n. , holotype, male. Spermatheca of characteristic structure ( Fig. 24 ). COMPARATIVE REMARKS. The new species is similar to C . ( B .) chagosanus in colouration, size and body morphology, but can be clearly distinguished by aedeagus morphology, especially by long, characteristically curved parameres. The new species is also similar to C . ( B .) filous (see above), but differs in a larger body size and the details of aedeagus morphology ( Figs 22–23 ). Рис. 20–21.

Indonesia , Sulawesi Island. ETYMOLOGY. From Latin “filo” (thread, stretch into a thread) and “longi” (long, lengthy); the name refers to the morphology of parameres; they are long and thin at their apices.
