Holotype, male (Fig. 86a). Length 2.43 mm. Color of antennae and legs ferruginous; remainder black. Body subovate; in profile dorsally convex. Rostrum dorsally in basal 1/2 with median and pair of submedian costae; intervening furrows with sparse rows of recumbent piliform scales; apical 1/3 subglabrous, sparsely setose. Pronotum with disk densely punctate with small punctures; interspaces between punctures subglabrous. Elytra irregularly punctate with small punctures, along basal margin with transverse row of denser punctures; some striae marked by hardly visible hairlines; intervals flat; stria 8 along humerus with six larger punctures; apex markedly angulate. Legs long. Femora edentate. Meso- and metafemur with anteroventral ridge crenate. Metafemur dorsally with row of recumbent, silvery scales; subapically with stridulatory patch. Metatibia ventrally with row of sparse, thin setae. Abdominal ventrites 1–2 concave, subglabrous; ventrite 5 at middle with ovate subglabrous pit laterally bordered by ridges, subapically with denticle. Penis (Fig. 86b) with sides of body subparallel; apex asymmetrical, with short extension on right side, with sparse setae; apodemes 2.3 × as long as body of penis; transfer apparatus spiniform, directed basad in repose, attached to anchor-shaped supporting sclerite; ductus ejaculatorius without bulbus.
