Diagnostic description
Holotype, male (Fig. 75a). Length 1.78 mm. Color black; antenna and tarsi ferruginous; tibiae and femora dark ferruginous. Body subovate; in dorsal aspect and in profile with marked constriction between pronotum and elytron. Rostrum with submedian and sublateral pair of furrows; epistome simple. Eyes large, divided into dorsal and ventral portions by marked incision of posterior margin. Pronotum with marked subapical constriction; densely punctate with deep punctures; each puncture with one narrow, elongate, ochre scale. Elytra with striae deeply incised; intervals costate, each with one row of narrow scales. Metafemur subapically without stridulatory patch. Tibia apically confluent with stout uncus. Onychium ca. 1.9× longer than tarsomere 3. Aedeagus (Fig. 75b) dorsoventrally flattened, widened to subangulate apex; transfer apparatus short, tubuliform. Intraspecific variation. Length 1.78–2.10 mm.
