Description. Length 3.5-4.0 mm; moderately elongate, convex, shiny, glabrous. Dark reddish brown, legs somewhat paler, antennal club testaceous. Head with epistome feebly convex on disc, medially depressed toward clypeal margin, distinctly, irregularly, not densely punctured; clypeus feebly sinuate at middle, round at sides, verythinly bordered, edge glabrous anddistinctly upturned on each side of median sinuosity; genae round, not ciliate, not protruding from the eyes; the latter rather large; frontal suture almost obsolete; front coarsely irregularly punctured. Pronotum transverse, moderately convex, dually not closely punctured; large punctures, seven to eight times larger than small ones, irregularly scattered, very sparse and superficial on sides, lacking on disc; small punctures irregularly, not closely scattered throughout, finer and sparser on disc; lateral margins feebly arcuate, thinly bordered, edge glabrous; hind angles obtusely round; base feebly bisinuate not bordered. Scutellum flat, rather finely irregularly punctured on basal half. Elytra faintly widened posteriorly, rather deeply striate; striae distinctly punc- tured, feebly crenulate; interstriae almost flat near imperceptibly sparsely punctured. Hind tibiae superior apical spur shorter than first tarsal segment; latter longer than following three segments combined. Male: headand pronotum somewhatmore transverse, less convexand lesscoarsely punctured; metasternal plate longitudinally grooved medially; aedeagus Fig. 158-159 . Female: head and pronotum somewhat less transverse, more convex and more coarsely punctured; metasternal plate nearly flat.
