This largely Central African species has been recorded from eastern Democratic Republic of the Congo, Uganda, extreme southern Sudan, northwest Tanzania and northern Zambia. The distribution is between 5°N and 8°S extending on the right bank of the Zaire River between (from west to east) the Ubangi River and Nile River and western shores of Lake Victoria, and south to the Mweru-Wantipa flats. There is an extralimital record from Maryal Bai and Malek in southern Sudan, and they may well be contiguous with the specimens collected further south. This species might also occur in Central African Republic, although this needs to be confirmed.
