Adults are generally oval in shape with straight sides along the middle. They are dark reddish-brown to blackish with a metallic iridescence. The head is fully visible when viewed from above. The exoskeletal plate covering the thorax (pronotum) is smooth, shiny, and covered with very fine pits (punctures). It is narrower than the bases of the hardened wing covers (elytra).
