Head, pronotum and elytra dark reddish black; legs and ventral region reddish black to almost black. Head: Clypeus strongly contracted, not reflexed; surface rugose; apex truncated. Frons with 2 small transverse protuberances, not connected; surface strongly punctate. Mandibles simple, emarginated; apex not incised. Surface of mentum with strong punctation to sparse smaller punctation, with long setae at sides, glabrous medially. Galea ventrally without setae, with dense setae dorsally. Antennae with 10 antennomeres, club short. Pronotum: broader than longer, convex; base bordered; sides curved; without tubercles; anterior marginal bead incomplete; punctures small, wrinkled at side and apical region; without setae. Prosternum: Prosternal process laminate. Elytra: shape longer than broad, with rows of small punctures; elytral sutural striae not well defined throughout its extension, with rows of small punctures. Metathoracic wings well developed. Legs: protibia tridentate, apical teeth triangular, closer together in relation to basal teeth, mesotibia and metatibiae triangularly dilated toward apex, both with transverse carina distinct and setose. Protarsi not thickened. Basal metatarsomere clearly enlarged. Abdomen: Pygidium convex with sparse micropunctation. Propygidium without stridulatory area; densely punctate with sparse, short setae. Genital plates ( Fig. 3 ), ventromesial plates broad with shallow, circular impressions on surface, sides convergent, apex rounded with scattered setae; laterodorsal plates narrowed with apical border coarsely tridentate, without setae. Male ( Fig.5 ): Similar to female, except that the small transverse protuberances of the frons are slightly conical, with pointed apex. Basal border of last abdominal sternite weakly emarginate medially.
