Diagnostic description.

Holotype, male (Fig. 70a). Length 2.20 mm. Color of antennae and legs ferruginous; remainder black. Body subovate, in dorsal aspect and in profile with weak constriction between pronotum and elytron. Rostrum with median ridge and pair of indistinct submedian ridges, intervening furrows each with sparse row of mesad directed setae; anterior third scabrous; epistome with transverse ridge. Pronotum coarsely punctate, laterally reticulate, submedially interspaces longitudinally rugose, with median costa; with sparse, suberect, slender scales. Elytra with striae deeply impressed; each with row of minute suberect setae; intervals costate, subglabrous; intervals 1, 3, 5 more distinctly swollen, each with row of punctures; row of punctures on sutural interval dense, facing mesad towards incised suture. Femora with simple, crenate anteroventral ridge. Metafemur subapically with stridulatory patch. Protibia with uncus relatively long, stout. Metatibia apically with uncus, without premucro. Abdominal ventrite 5 coarsely punctate, with sparse suberect setae; with median carina. Penis (Fig. 70b) with sides of body converging, at middle with shallow constriction; containing several sclerites; apex sparsely setose, with median, subtriangular extension; transfer apparatus small, symmetrical, with pair of tendons attached, with median narrow apically biramose sclerite; apodemes 2.7 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.20-2.31 mm. Color of sutural interval and elytral apex ferruginous or darker, almost black. Female unknown.
