Diagnostic description.

Holotype, male (Fig. 93a). Length 2.68 mm. Color black; legs deep ferruginous, antenna light ferruginous. Body ovate, with weak constriction between pronotum and elytron; in profile almost evenly convex. Rostrum dorsally in basal half rugose-punctate, in apical half punctate. Pronotum densely punctate except along partly impunctate midline. Elytra densely punctate with small punctures; striae impressed as fine lines; intervals with confused punctures; lateral stria behind humeri with row of deep punctures. Femora in apical 1/3 with anteroventral ridge terminating as tooth. Metafemur with denticulate dorsoposterior edge; subapically with stridulatory patch. Metatibia apically with uncus, premucro, and supra-uncal tooth. Aedeagus (Fig. 93b) medially weakly extended; transfer-apparatus asymmetrical, spiniform, curved; endophallus basally with shell-shaped sclerite; ductus ejaculatorius with bulbus. Intraspecific variation. Length 2.50-2.78 mm. Female rostrum dorsally subglabrous, sparsely punctate, basally sparsely squamose.
