Africa: Ogooué and Djoungou River drainages (Gabon) southwards to the drainages of the Kouilou and Loeme (Republic of Congo), Chiloango, Luculla and Quanza (Angola) and the lower Congo River (Ref. 3570, 78218, 81643).

Maturity: Lm ? range ? - ? cm
Max length : 7.5 cm SL mannelijk / geslacht onbekend; (Ref. 81643)
Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 0; Anale stekels: 0; Anale zachte stralen: 51 - 68. Diagnosis: adipose fin present; inner side of pectoral spine feebly serrated, with small to very small serrations; 51-68 soft anal fin rays; vomerine teeth usually absent; a dark triangular blotch at base of caudal fin (Ref. 43912, 81643).
Confined to large and moderate rivers; sometimes penetrates into estuaries; gregarious schooling species, such schools probably an important prey for several larger carnivorous species (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Maximum TL reported 85 mm (Ref. 43912).
