Redescription.
Length 5.0-6.0 mm, oblong, moderately convex, shiny, glabrous. Brown-reddish; head anteriorly, sides of pronotum and elytra reddish-testaceous; latter, on preapical declivity, with a rounded paler spot vaguely surrounded by a piceous border; legs pale brown-reddish; antennal club brownish. Head with epistome feebly convex, finely, regularly and sparsely punctured throughout; clypeus faintly truncate anteriorly, widely rounded at sides, thickly bordered, border somewhat thickened anteriorly; genal sutures distinct; genae small, somewhat depressed; obtusely angulate, almost not ciliate, protruding beyond eyes; frontal suture obsolete; front finely, sparsely and regularly punctured. Pronotum transverse, feebly convex, finely microreticulate so subshiny on disc, dually punctured; large punctures, two to three times larger than small, densely scattered on sides only, mixed small punctures somewhat coarser and denser anteriorly and laterally; lateral margins subparallel, thinly bordered; hind angles obtusely truncate, faintly inwardly sinuate; base distinctly bisinuate. Scutellum narrow, apically acuminate, finely microreticulate, impunctate. Elytra oval-elongate, subparallel-sided, faintly denticulate at shoulder; striae fine, superficially punctured, subcrenulate; intervals almost convex, shiny, finely and sparsely punctured on disc, preapically flat, impunctate and strongly microreticulate so dull. Hind tibiae superior apical spur a quarter shorter than first tarsal segment; latter longer than following three combined. Male: head and pronotum relatively more transverse, less convex and more sparsely punctured; fore tibiae slender and more elongate; their apical spur short, stout and downward bent; metasternal plate excavate at middle, finely and sparsely punctured, median longitudinal groove moderately impressed; aedeagus
