Diagnostic description

Holotype (Fig. 26a). Length 2.88 mm. Color ferruginous. Body subovate, with distinct 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 narrow scale; base dorsally protruding, markedly projecting from profile subangularly; epistome posteriorly with subangulate ridge. Forehead coarsely punctate-rugose. Pronotum with distinct subapical constriction; disk coarsely punctate-reticulate; with median costa; uneven, with weak swelling at center of disk; punctures each containing one narrow ochre scale. Elytra with striae deeply incised; intervals costate-carinate; with rows of narrow ochre scales and larger white scales; base markedly bisinuate. Legs. Femora densely punctate, with sparse ochre scales, with transverse band of larger white scales. Profemur with subbasal callus anteriorly projecting. Tibiae subbasally with dorsal angulation; metatibia with suprauncal tooth. Abdominal ventrites 1-2 laterally swollen, medially forming common cavity, with coarse punctures; ventrite 5 weakly concave, in basal half with ochre scales. Penis (Fig. 26b) with sides of body subparallel, with constriction in front of middle, continued subparallel to subangulate apex; transfer apparatus flagelliform, directed basad, its length subequal to body of penis; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.58–3.08 mm. Color ferruginous or almost black with only tarsi and antenna ferruginous. Female rostrum with median costa and pair of submedian costae; epistome simple. Female abdominal ventrites 1-2 medially flat; ventrite 5 flat.
