This speciess is primarily found in central and southern Sudan but it extends into Ethiopia, Kenya and Uganda. It occurs well below 2,000 m asl, and it is not found in the highlands of Ethiopia. It is not present in the Gambela area of Ethiopia which is too low lying and very wet. There are outlying records from Jebel Mara, the base of the jebels in eastern Sudan, Bahr el Ghazal and the Immatongs in Uganda. The occurrence of this species in Djibouti requires confirmation.
