Body moderately large, oblong oval, dorsum moderately convex, finely punctate and pubescent. Head transverse oval, eyes large, finely faceted, entire, narrowly margined and not extending to underside of head (Fig. 1). Antennae small, geniculate, composed of 8 or 9 antennomeres, antennomere 1 large, 2 slightly smaller and subtriangular, the rest together forming a spindle or an elongate oval club (Fig. 3). Terminal maxillary palpomere securiform (Fig. 4). Pronotum transverse, at middle of length twice as wide as long, strongly convex, anterior margin deeply emarginated. Scutellum subtriangular. Elytra oblong oval, moderately convex. Humeral callus rather prominent, obtusely. Prosternum T-shaped, evenly convex (Fig. 2), prosternal lines as wide apart as the width of the base of the prosternal process, widely divergent; the area between them extremely convex and widening anteriorly to form a chin-band, usually with coarse punctures and long pubescence (Fig. 5). Both sides of prosternum deeply foveate to accommodate apices of front femora (Fig. 2). Mesoventrite transverse, widely emarginated anteriorly, indistinctly punctate and sparsely pubescent. Metaventrite usually finely punctate, with dense pubescence. Elytral epipleuron narrow, incomplete, with clearly delimited cavities to accommodate apices of mid and hind femora. Abdomen with 6 ventrites, the first being dilated posteriorly in an arc at middle, abdominal postcoxal lines incomplete (Fig. 10). Legs with femora broadly expanded, oval, and completely concealing the compressed tibiae (Figs 8–9), tarsi composed of three tarsomeres (Fig. 11). Male genitalia: Penis curved, with a distinct penis capsule. Penis guide in ventral view flat and broad, apex pointed or truncate. Parameres slender, with sparsely distributed short setae at apex, nearly as long as penis guide. Female genitalia usually with tenth tergite broad, setose, coxites subtriangular or broad.
