Diagnostic description.

Holotype, male (Fig. 70a). Length 1.78 mm. Color of antennae and legs ferruginous; remainder black. Body subovate; in dorsal aspect with weak constriction between pronotum and elytron, in profile dorsally convex. Rostrum dorsally with median costa and pair of submedian ridges; intervening furrows with sparse rows of short setae; epistome indistinct. Pronotum with ovate punctures of transverse orientation; interspaces subglabrous. Elytra with striae marked by rows of distinct punctures; sutural interval with additional row, other intervals subglabrous, with few interspersed punctures. Femora with anteroventral ridge crenate, ending with blunt angulation; anterior surface weakly rugose, weakly denticulate, microreticulate. Metafemur subapically with stridulatory patch. Abdominal ventrites 1-2 markedly microreticulate, almost impunctate, concave; ventrite 5 coarsely punctate, with depression at middle. Penis (Fig. 70b) with body subparallel, weakly rounded to subtruncate apex; apodemes 2.0 × as long as body of penis; transfer apparatus flagelliform, 2.4 × longer than body of penis; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.78-1.90 mm. Female rostrum subglabrous, with two submedian rows of punctures, with pair of sublateral furrows.
