Holotype, male (Fig. 69a). Length 1.78 mm. Color of antennae and tarsi ferruginous; remainder dark ferruginous to black, with slight bronze lustre. Body subovate, in dorsal aspect and in profile with weak constriction between pronotum and elytron. Rostrum with median ridge and pair of submedian ridges, intervening furrows each with sparse row of mesad directed scales; epistome simple. Pronotum coarsely punctate, interspaces longitudinally rugose; with median costa; with sparse, subrecumbent scales. Elytra with striae deeply impressed, each with row of slender suberect scales; intervals costate, subglabrous; incised suture bordered by row of squamiferous punctures, partly overgrown by costate sutural interval. Femora with simple, crenate anteroventral ridge. Metafemur subapically with stridulatory patch. Metatibia apically with uncus and small premucro. Abdominal ventrite 5 coarsely punctate, except apical third subglabrous. Penis (Fig. 69b) with sides of body subpar
