Redescription (translated from Villiers et al. 2011): Length 19–25mm. Black head with red labrum and palps. Red antennae. Black pronotum with prostrate pubescence. Black scutellum. Elytra black with a narrow yellow band, clearly defined, extending from the shoulder almost to the apex; the yellow band with golden pubescence, and the black area with silvery pubescence. Red forelegs. The mid and hind legs black, tarsi red. Ventral surface black with fine silvery pubescence. Head densely punctate; genae one and a half times longer than the lower eye lobe. Frons approximately one and a half times (male) to two times (female) wider than an eye seen from a dorsal view. Antennae extend beyond the apex of the elytra (male) or only reach the level of their apical quarter (female). Pronotum approximately as long as wide at the base (male) or transverse (50/60) (female), with slightly convex sides on their posterior half, very strongly converging forward on their anterior half; very convex disc, with very weak tubercles; collar and basal margins strongly depressed, clearly delimited. Elytra narrow, 2.8 times as long as they are broad when held together (closed) at the base, with strongly protruding shoulders; male tibia with a small dentiform process at the apex of the inner surface.
