maximal breadth. Pronotum moderately transverse, MPW/PL = 1.18-1.22, cordate, lateral margins convergent before acute, projected hind angles; median base depressed relative to convex disc, smoother medially with 9-10 punctures laterally each side; anterior transverse impression broad, shallow, smooth, with at most three indistinct longitudinal wrinkles each side near middle, anterior callosity smooth, slightly convex; front angles rounded, slightly protruded; lateral marginal depression narrow, edge beaded, slightly wider inside front angle; laterobasal depression deep, surface rugose to irregularly punctate, margined laterally and basally by raised margin. Elytra ovate, MEW/HuW = 2.08-2.20, humeri angulate laterad evenly curved basal groove; disc convexly domed above depressed scutellum, sides sloped to near vertical juncture with lateral marginal depressions, sutural intervals of each elytron raised as a broad callous joined at the elevated suture; elytral striae 1-7 smooth, continuous, minute punctures at depth of stria on disc the only indication of punctation, striae 1-6 continuous and deep to basal groove, striae 1+2 fused for short distance from laterad parascutellar seta to basal groove; interval 8 convex laterally, upraised slightly laterad stria 7 apicad fused terminus of striae 3 + 4; lateral elytral setae 7 + (5-6). Coloration of head rufobrunneous, clypeus and labrum rufous; antennomere 1 flavous, 2-3 rufoflavous; 4-11 rufobrunneous; pronotal disc dark rufobrunneous, the anterior callosity and lateral margins narrowly, and median base more broadly, rufous; elytral disc rufobrunneous with silvery metallic reflection, the apex concolorous with disc, upraised sutural interval rufous, lateral marginal depressions narrowly rufoflavous, palest apically; femora and tibiae rufoflavous.
