Body subovate; in dorsal aspect with weak constriction between pronotum and elytron; in profile dorsally convex. Rostrum dorsally with somewhat flattened median costa and pair of submedian costae; intervening furrows with sparse rows of recumbent setae; apical 1/3 subglabrous, with few punctures and with sparse setae. Pronotum with disk densely punctate with coarse punctures except along impunctate median line; interspaces between punctures subglabrous, microreticulate, subequal to or smaller than punctures' diameter. Elytra with striae marked by punctures and fine hairlines; basal margin bordered by transverse row; intervals flat, microreticulate, with few interspersed punctures. Femora edentate; anteroventral ridges simple. Metafemur dorsally with sparse, recumbent, silvery scales; dorsoposterior edge simple; subapically with stridulatory patch. Metatibia ventrally with sparse row of setae. Abdominal ventrites 1-2 concave, subglabrous, sparsely punctate; ventrite 5 at middle with distinct, broadly ovate impression, densely punctate. Penis (Fig. 84b) with sides of body subparallel; apex subtruncate, with median angulate extension, with sparse setae; apodemes 1.8 x as long as body of penis; transfer apparatus spiniform, directed basad in repose, attached to anchor-shaped supporting sclerite; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.24-2.56 mm. Female rostrum slender, subglabrous, with two submedian rows of punctures, with pair of sublateral furrows. Material examined.
