Holotype, male (Fig. 62a). Length 1.88 mm. Color of antennae and legs ferruginous; remainder black. Body subovate, in dorsal aspect with weak constriction between pronotum and elytron; in profile dorsally convex. Rostrum with median ridge and pair of submedian ridges, intervening furrows each with sparse row of mesad directed setae; epistome simple. Pronotum with coarse punctures partly forming longitudinal rows; each puncture containing long recumbent seta; interspaces sub glabrous, especially midline. Elytra with striae distinct; each puncture containing one recumbent seta; intervals flat, subglabrous. Femora with simple, crenate anteroventral ridge. Metafemur subapically with stridulatory patch. Metatibia apically with uncus, without premucro. Abdominal ventrite 5 coarsely punctate, sparsely setose, flat. Penis (Fig. 62b) with sides of body subparallel; apex sparsely setose, converging to median triangular extension, curved ventrad; transfer apparatus compact, symmetrical, with two pair of tendons attached; laterally with pair of sickle-shaped sclerites; apodemes 2.8 × as long as body; ductus ejaculatorius without bulbus.
