Frons flat, just impressed before the anterior margin, this moderately and regularly arcuate, protruding above the clypeus; punctuation moderate, uniformly d istributed, punctures deep, simple, approximately of the same size with smooth intervals on average equal to a little smaller than their own diameters.
Antennae not reaching for about two articles the apices of posterior angles of pronotum, slightly serrated from the third article; second article subcylindrical, twice longer than wide and 1,35x shorter than fourth; fourth-tenth conical, subequal in length and on average 2,5x longer than wide, last sub ellipsoidal.
Pronotum 1,1x longer than wide, widest at the middle, regularly convex; sides regularly arcuate, posterior angles short, truncate, not divergent with a short carina; lateral suture-like margins substraight and complete; punctuation dense, uniformly distributed, double; larger punctures are more or less regularly mixed with much more fine punctures, intervals very short and smooth.
Scutellum heart-shaped, as long as wide, impressed, emarginate at middle of the base, vey finely punctu red.
Elytra 2,34x longer than pronotum and wide as it, convex; sides widest before the middle then very gradually converging to the apices; striae well marked and punctured, interstriae subconvex with very fine punctures.
