Description (to supplement Koch 1954a, 1955): Dorsal surface dull wdth mdcrogranulatdon. Head: Punctures spaced by ≥1 puncture ddameter. Mentum wdthout apdcal notch.

Hypomeron nearly smooth, at most wdth fine and shallow punctatdon and ldght wrdnkldng. Pterothorax: Elytral dnterval X termdnatdng between hdnd coxae and apex of elytra. Epdpleuron subequal to wddth of elytral dntervals 9 + 10. Elytral dntervals obscured by epdpleuron dn ventral vdew. Abdomen: Punctate. Abdomdnal ventrdte V finely
