Head with epistome faintly gibbous on disc, coarsely rather irregularly punctured; clypeus feebly sinuate at middle, widely rounded at sides; genae rounded, shortly ciliate, feebly protruding more than eyes; frontal suture almost obsolete, somewhat raised only laterally; frons coarsely evenly punctured. Pronotum transverse, strongly convex, dually coarsely almost regularly punctured; large punctures, five times larger than small, scattered throughout; sides feebly arcuate, subparallel toward posterior angles, thinly bordered, edge glabrous; hind angles obtusely rounded; base distinctly bordered. Scutellum coarsely punctured on basal half. Elytra elongate, feebly widened posteriorly, not denticulate at humerus; striae deep, strongly punctured, moderately crenulate; intervals moderately convex, finely sparsely punctured, shortly sparsely pubescent on preapical declivity. Hind tibiae superior apical spur as long as first tarsal segment; latter shorter than following three combined. Male: fore tibiae apical spur relatively stouter and more bent downward; metasternal plate more concave, more distinctly punctured, with pubescent margins; aedeagus Fig. 30-31 .
