Entorno: milieu / zona climática / rango de profundidad / gama de distribución
Ecología
; agua dulce bentopelágico. Tropical
Africa: coastal plain of West and Central Africa from the lower Volta River (Ghana) to the Chiloango system (Angola and Congo DR)(Ref. 44050, 57130, 81645), and on the island of Fernando Po (Ref. 44050).

Espinas dorsales (total) : 0; Espinas anales: 0; Radios blandos anales: 8 - 11; Vértebra: 33 - 38. Diagnosis: body cylindrical; tooth patches narrow; vertically oriented pectoral fins, placed near body mid-depth; 6-7 branched caudal-fin rays; pectoral-fin rays usually 8, rarely 7 or 9; 34-38 vertebrae; eyes relatively small, interorbital space relatively broad; caudal saddle and bar pattern quite distinct in juveniles and young and usually apparent in adults (Ref. 44050), but often subdued (Ref. 81645). Dorsum and flank nearly always spotted, sometimes extensively (Ref. 44050, 81645). Commonly 10-15 gill rakers on first arch (total range 4-22)(Ref. 44050). Caudal saddle and anal-fin pigmentation not continuous (Ref. 44050, 81645). Venter often dusky, occasionally lightly spotted (Ref. 81645).
Body shape (shape guide): fusiform / normal; Cross section: circular.
