Africa: streams in south-eastern Tanzania near Korogwe (Ref. 4983). Also reported from Pangani drainage and Tsavo basin in Kenya (Ref. 30558, 52331). The status of the population of Mzima Springs in Tsavo basin is uncertain; it might be distinct from Ctenopomis pectoralis known from the Pangani drainage (Ref. 52331). In the IUCN Red List this species is erroneously recorded as 'extinct', since it is probably confused with another cichlid species of Lake Victoria, Haplochromis squamulatus (Ref. 127080).
