The pronotum is twice as broad as long, slightly narrowed from base to apex, with sides feebly curved and narrowly margined.
The apex of the pronotum is broadly emarginated with apical angles prominent. The pronotal base is bisinuate with basal angles rectangular. There is a shallow impression on each side of the pronotum in the middle near the base. The pronotal disk is finely and sparsely punctured, with punctures much coarser laterally.
