The scutellum bears sparse punctures. On the moderately densely punctured elytra, which are somewhat widened behind the middle, only the sutural rib and the second primary rib are more clearly marked. Both are only very sparsely punctured. The pygidium is weakly wrinkled. The thorax is covered with yellow hairs, and the abdomen almost smooth.
