Eastern Atlantic: St. Louis (Senegal) to the Cunene River (Angola) and from the islands of the Gulf of Guinea (Ref. 5299, 57403). Also reported from the East Coast drainage of Africa (Tanzania) (Ref. 4967) and from Namibia (Ref. 33857).

Biology     Glossary (e.g. epibenthic)

Amphidromous freshwater species (Ref. 92840). Often found in lower courses of rivers, ranging from freshwaters to brackish habitats (Ref. 57403), including brackish waters of intermittent streams during dry seasons (Ref. 5299). May also ascend rivers, far upstream (Ref. 57403). Also found in flooded fields and marginal swamps along courses of streams and rivers (Ref. 5299).
