Holotype (Fig. 7a). Length 2.73 mm. Color black; antenna and legs ferruginous. Body subovate, with shallow constriction between pronotum and elytron; in profile convex. Rostrum with median ridge and pair of submedian ridges ending in apical third; intervening furrows with rows of coarse punctures each containing one mesad directed seta; base dorsally protruding, markedly projecting from profile subangularly; epistome posteriorly with curved ridge bearing 4 low denticles. Forehead coarsely punctate-rugose. Pronotum with indistinct subapical constriction; disk coarsely punctate-reticulate; with median costa; near middle with pair of very weak swellings, further laterad with clusters of yellow recumbent scales. Elytra with striae deeply incised; intervals costate, microreticulate, with shallow punctures and few scattered recumbent scales; base markedly bisinuate. Legs. Femora densely punctate. Profemur with subbasal callus anteriorly projecting. Tibiae subbasally with dorsal angulation. Abdominal ventrites 1-2 laterally swollen, medially forming common cavity; ventrite 5 punctate, flat. Penis (Fig. 7b) with sides of body weakly converging, at middle with constriction, widening to subtriangular apex; transfer apparatus flagelliform, ca. 1.5× longer than body of penis; ductus ejaculatorius near insertion to transfer apparatus sclerotized, without bulbus.
