A common East African species ranging from the Orange 

 Free State to Uganda. Cirerstaecker mentions only one 

 tooth on the tarsal ungues in his description, but there can 

 be no doubt that his description applies to this species and 

 that he overlooked the basal tooth. The clypeus of the male 

 is usually black, but sometimes fusco-ferruginous as in the 



type.
