Redescription. Length 2.5-3.0 mm, shortly oval, strongly convex, glabrous; shiny, elytra feebly alutaceous. Reddish-testaceous, elytralsuture darker; legs brown-reddish; antennalclub brownish. Head subtrapeziform; epistome finely, nearly regularly, sparsely punctured, with median longitudinal carina anteriorly furcate, each branch obliquely extended almost till clypeal margin; clypeus sinuate at middle, round at sides, rather finely bordered, edge glabrous; genae small, round, faintly bristled, not protruding from theeyes; frontal suture strongly impressed, anteriorlyfeebly carinate. Pronotum dually punctured, throughout scattered smallpunctures somewhat coarser than those of head, larger punctures, six times larger than small ones, sparse on disc and more dense at sides; lateral margins parallel on basal half, regularly curved toward front angles; hind angles obtusely round; base feebly bisinuate. Scutellum narrow, somewhat subparallel sided at basal fourth, with some small punctures near base. Elytra finely striate; striae feebly crenulate; interstriae flat on disc, feebly convex on preapical declivity, superficially microreticulate, finely and sparsely punctured. Fore tibiae with one or two proximal denticles, their apical spur slender and rather elongate, as long as first two tarsal segments combined. Hind tibiae superior apical spur somewhat shorter than first tarsal segment; latter shorter than following two segments combined. Male: pronotum somewhat less densely punctured on disc; inferiorapical spur of middle tibiae relative shorter than superior one; aedeagus Fig. 96-97 . Female: pronotum somewhat more densely punctured on disc; inferior apical spur of middle tibiae as long as superior one.
