Range DescriptionMastacemebelus frenatus is known from Uganda and Kenya, south to Namibia and Botswana.
Central Africa: It has been found in the Kasai, the upper Congo and the Luapula-Mweru system.
Eastern Africa: This species is present in the Lake Victoria drainage. Also known from the Nabugabo systems, the Victoria Nile and Aswa River, as well as Tanganyika and major affluents, i.e. Rusizi and Malagarazi, Akagera, Lake Kyoga and associated smaller lakes and rivers. Records by Copley (1952, 1958) from the Athi River system might refer to this species. Most likely there are no mastacembelids in the Tana system despite records by Copley (1952, 1958) (Seegers et al. 2004).
Southern Africa: It occurs in the upper Zambezi, Okavango and Kafue systems (Skelton 2001), and is widespread throughout the upper Zambezi system including many northern tributaries such as the Kabompo and West Lunga (Tweddle et al. 2004)
