Range DescriptionA freshwater species, occurring in rivers and lakes of West Africa: Nigeria from Old Calabar River, Gabon from Lake Ezanga and the Ogooué River system and Democratic Republic of Congo from the Congo River at Binda (Smith 1863, Compagno and Roberts 1984a,b). Also possibly from marine coastal waters of Nigeria, according to the original description (Smith 1863), but this needs verification. All modern records are from fresh water.
Subpopulation details are unknown. There could be discrete populations in different rivers, or interchange between the river systems may take place by individuals transiting in coastal marine environments.
