diagnosis
Diagnosis The male of H. perater Cockerell can hardly be mistaken for the bulging, completely black face and the globular, thickened scapi. The differences between the females of this group are slight.
discussion
Remarks According to the male terminalia, this species is probably closely related to H. robertianus, H. krebsianus and H. gabonicus (robertianus-group). The punctation on T 1 can vary, in the material studied it is a little closer in males of Zimbabwe, and more fine in males from Kenya.
