Range DescriptionThis species is present in river, streams and swamps along the western coast of Africa from the Gambia drainage (Gambia) to the Quanza (Angola) (Dawson 1981, 1986).
Central Africa: It is present along the coast from Cameroon to Angola. In contrast to M. brachyurus aculeatus, E. ansorgii is found only in some smaller tributaries of the Lower Kouilou (Congo) and not in the main river (Snoeks, pers. obs.).
Southern Africa: In Angola, the species occurs in the Kwanza River system.
Western Africa: Known from rivers and marshes from Gambia river basin, it does not appear to be collected in marine environment, nor in estuaries.
