Diagnostic description

Holotype (Fig. 8a). Length 2.88 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, projecting from profile subangularly; epistome posteriorly with 4 low denticles. Forehead coarsely punctate-rugose. Pronotum with subapical constriction; disk coarsely punctate-rugose; with median costa; submedially punctures confluent forming irregular longitudinal furrows and wrinkles, near middle sparing pair of weak swellings of irregular outline. Elytra with striae deeply incised; intervals costate, sparsely punctate, with few scattered recumbent white scales; base markedly bisinuate. Legs. Femora densely punctate. Profemur with subbasal callus anteriorly projecting. Tibiae subbasally with dorsal angulation; metatibia subapically with suprauncal denticle. Abdominal ventrites 1-2 laterally swollen, medially forming common cavity; ventrite 5 punctate, weakly concave. Penis (Fig. 8b) with sides of body subparallel, apex rounded; behind ostium with pair of sclerites; endophallus with pair of elongate sclerites; transfer apparatus flagelliform, ca. 1.6× longer than body of penis; ductus ejaculatorius near insertion to transfer apparatus sclerotized, this portion longer and thicker than flagellum; without bulbus. Intraspecific variation. Length 2.60–2.90 mm. Female body more slender. Female rostrum dorsally somewhat flattened; median costa and pair of submedian costae subglabrous; epistome simple. Female abdominal ventrites 1-2 medially flat; ventrite 5 coarsely punctate, basally swollen, apically flat.
