Holotype, male (Fig. 17a). Length 2.12 mm. Color black; antenna light ferruginous; legs deep ferruginous. Body subovate, with shallow constriction between pronotum and elytron; in profile evenly convex. Rostrum in basal half medially carinate, with pair of sublateral furrows posteriorly converging on forehead; weakly punctate, sparsely setose; epistome with transverse, angulate ridge. Pronotum with subapical constriction dorsally distinct, laterally indistinct; disk with longitudinal impressions, sparsely punctate, sparsely setose. Elytra with striae deeply incised, towards sides with deep interspersed punctures; intervals costate-carinate, subglabrous, with sparsely setose with minute recumbent setae; apex rounded. Femora edentate. Metafemur with simple dorsoposterior edge, in apical third with transverse row of small suberect setae, subapically with stridulatory patch. Abdominal ventrite 5 basally with pair of teeth. Aedeagus (Fig. 17b) apically subangulate, glabrous; with complex, symmetrical transfer apparatus; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.06–2.12 mm. Female rostrum in basal half with median carina less distinct.
