Diagnostic description
Holotype, male (Fig. 68a). Length 2.57 mm. Color black; antennae and tarsi ferruginous. Body subovate; with weak constriction between pronotum and elytron; in profile evenly convex. Rostrum in basal half with distinct median ridge and pair of submedian ridges, furrows with sparse rows scales and setae; apically weakly punctate, sparsely setose. Pronotum punctate-reticulate. Elytra with striae impressed as very fine lines; strial punctures very small; intervals flat, subglabrous; basal margin bordered by row of small punctures; laterally behind humeri with ridge bordered by 4 deep punctures of stria 9. Femora edentate. Mesofemur and metafemur dorsally squamose with silvery scales. Metafemur with weakly denticulate dorsoposterior edge; subapically with stridulatory patch. Metatibia apically with uncus and minute premucro. Abdominal ventrite 5 densely setose with erect setae. Aedeagus (Fig. 68b) apically weakly pointed, sparsely setose; body dorsally with 2 rows of sparse setae; in profile apical 2/3 of body markedly curved ventrad; transfer-apparatus spiniform; ductus ejaculatorius with bulbus. Intraspecific variation. Length 2.30–2.65 mm. Female rostrum in apical half dorsally subglabrous, sparsely punctate, with shallow furrows. Female abdominal ventrite 5 with subrecumbent setae.
