Length: 7,29–8,91 mm.

Head: black. Large pale macula extending to the vertex, rounded. Two pale maculae visible at the lower portion of the frons. Mouthparts: labrum with 12 setae. Antennae: black.

Prothorax: pronotum yellowish. Metathorax and mesothorax: with the same color as the head. Elytra: elytral integument reddish. Six large rectangular pale maculae visible; maculae equidistant, two in the proximal portion of the elytra, two in the median portion and two in the distal portion. Scutellum triangular, posterior portion rounded. Legs: black.

Abdomen: brownish. Male Aedeagus Median lobe ( Fig. 21 ): ventral sclerite visible in dorsal view; longer than the sides of the median lobe, apex acuminated. Dorsal median process visible; proximal portion of the dorsal median process and apex with subequal width; with two wide divergent projections at the apex, triangular-shaped. Dorsal lateral sclerites visible, subtrapezoid, poorly defined. Oblique dorsal process ventrally curved. Female Tignum ( Fig. 27 ): Base wider than the apex; hood-like structure in the median portion present ( Fig. 4 ); median portion opaque; distal portion slender, lateral margins divergent; apex rounded.
