Elytra strongly convex, feebly widened apically; striae almost superficial, distinctly punctate, crenulate; interstriae flat, with a longitudinal row of microscopic punctures near lateral margins only, apically somewhat more distinctly punctate. Metatibiae superior spur as long as first metatarsomere; latter longer than following 2 metatarsomeres combined. Male: median tubercle of frontal suture distinct; pronotum not narrowed apically, without large punctures on disc; protibiae spur downward bent, feebly hooked apically; inferior spur of mesotibiae distinctly hooked apically; aedeagus Figs. 45–46 .
