Head: Genae and epicranium expand­ ed; interocular depressions and frontal umbo prominent; frons, epicranium, and gena very finely punctate; eyes subspherical, moderately convex; width across eyes greater than width across pronotum (38:35); antenna elongate, as long as length of pronotum (40: 40). Thorax: Pronotum longer than wide (35: 40), very finely punctate, anterior transverse depression poorly defined, side margins feebly arcuate, considerably narrower than width across humeri (35:43); elytra boldly convex, depth at humerus 15, greatest depth in posterior half 25; metafemora not extend­ ed beyond elytral apex.
