Diagnostic description.

Holotype, male (Fig. 89a). Length 3.44 mm. Color black. Body subovate; with distinct constriction between pronotum and elytron; in profile evenly convex. Rostrum dorsally rugose-punctate, basally with median ridge and indistinct pair of submedian ridges, furrows with sparse rows of setae and yellowish scales. Pronotum densely punctate. Elytra densely punctate; striae distinct, consisting of small punctures; intervals with row of minute punctures; laterally behind humeri with ridge bordered by dense row of deep punctures of stria 9. Femora edentate. Mesofemur and metafemur dorsally densely squamose with silvery scales. Metafemur with denticulate dorsoposterior edge; subapically with stridulatory patch. Metatibia apically with uncus and small premucro. Abdominal ventrite 5 with shallow impression, densely punctate, with sparse erect setae. Aedeagus (Fig. 89b) apically pointed, with tuft of long setae; body containing pair of elongate sclerites; transfer-apparatus symmetrical, with lyriform sclerite; ductus ejaculatorius with bulbus. Intraspecific variation. Length 2.91-3.58 mm. Body of females more slender than males. Female rostrum in apical 2/3 slender, dorsally subglabrous, with submedian rows of small punctures and lateral furrows. Pronotum of females basally at middle with punctures smaller and sparser, in males punctures evenly deep and dense. Female abdominal ventrite 5 flat, without erect setae.
