Bernhauer Collection// sikkimi det. Cameron Fauv // FMNHINS 2821331 FIELD MUSEUM. (FMNH); Redescription. Body dark brown; elytra brown, legs yellow. Forebody sparsely pubescent, coarsely punctate and densely striate. Body length male 4.0 mm; female, 3.60 mm . Male : Head (Fig. 20-1C, 20-2A) slightly broader than pronotum. Vertex flat, with small round punctures; midlongitudinal sulcus short and deep, with shallow impression on each side before base. Supra-antennal ridge with margin incrassate. Temples dilated, approximately two times as long as eyes. Clypeus nearly square, about 1/3 of total head length, slightly convex, coriaceous, with a few punctures, anterior margin rounded and produced. Epistomal suture with lateral portions straight and parallel, running backward to level of anterior margin of eyes. Occipital suture straight or slightly curved forward in middle. Antenna filiform, segment IV globular, VI–X short and transverse, with ultimate article stilliform. Neck without smooth area. Pronotum (Fig. 20-1D, 20-2A) transverse, broadest at near anterior 1/3; disc slightly convex, with some punctures and striae, denser at laterals; mid-longitudinal sulcus broad and deep, narrowing and deepening to base, and two shallow, straight paramedial sulci, bounded by obtuse longitudinal carina, with shallow depression close to lateral margins. Anterior margin nearly straight, anterior angles obtuse but produced. Lateral margin weakly crenate on posterior 1/3. Posterior angles not obvious. Scutellum with crest-shaped impression, with sharply pointed median lobe. Elytra with closely striate and punctate, not pubescent; lateral margin curved and posterior margins truncate and slightly slant. Abdomen coriaceous, covered with punctures and pubescence. Sternite VII (Fig. 20-1G, 20-2C) with posterior margin almost straight, and carrying long setae laterally, with two small tubercles in middle, not beyond posterior margin. Sternite VIII (Fig. 20-1H, 20-2D) with posterior margin broadly shallowly bi-emarginate and bearing long setae laterally, rectangulate in middle and running backward to level of lateral angles posteriorly. Aedeagus (Fig. 20-1J–L, 20-3A–C) with median lobe elongate, inflated at base and shortly narrowing to apex; apical orifice large and ventral orifice crescentic; internal sac of median lobe with simple sclerites. Parameres (Fig. 20-1M, 20-3D) arm-like, closely situated to each other; with short, thick seta near apex. Female . Head (Fig. 20-1E, 20-2B) smaller than male. Epistomal suture with lateral portions straight or slightly obliquely inward. Temples shorter than eyes. Sternite VII (Fig. 20-2E) with posterior margin slightly emarginate. Sternite VIII (Fig. 20-1I , 20-2F) with posterior margin broadly rounded and posteriorly gradually narrowing, with setae near posterior margin. Spermatheca (Fig. 20-1N, 20-3E) with base bulb-like, with apical part clavate and slightly curved. FIGURE 20-1.
