Holotype, male (Fig. 14a). Length 2.42 mm. Color black; base of elytra and legs ferruginous; antenna light ferruginous. Body subovate; in dorsal aspect with marked constriction between pronotum and elytron; in profile almost evenly convex. Rostrum dorsally scabrous, basally with indistinct median ridge; epistome forming angulate ridge. Pronotum moderately densely punctate. Elytra with striae marked by small punctures; interval 4 basally with cluster of few subovate, cream-colored, recumbent scales; interval 7 subapically forming indistinct ridge. Meso- and metafemur with anteroventral ridge weakly dentate. Meso- and metatibia in basal half widened, subapically narrowed; dorsal edge basally granulate; uncus large, peg-shaped. Metafemur with denticulate dorsoposterior edge, subapically without stridulatory patch. Aedeagus (Fig. 14b) with sides of body in apical third converging, apex rounded; orifice retracted; endophallus denticulate; transfer apparatus symmetrical; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.98–2.48 mm. Female rostrum dorsally subglabrous in apical half, with small punctures, epistome simple.
