This species is endemic to East Africa, occurring from the Masai Mara south-west through the Serengeti, around the southern shore of Lake Victoria, across to eastern Rwanda and Burundi and then south into southern Tabora District in Tanzania. It might also occur north of the Masai Mara, but this has not been confirmed. It occurs from 1,000 to 2,200 m above sea level (Spawls et al. 2002).
