Africa: Western Africa, from Senegal to Angola (Ref. 188, 3509); including lower Senegal River and lagoons in Côte d'Ivoire (Ref. 54749, 81269), Niger Delta (Ref. 81269), Ogowe River (Ref. 81631), and rivers between Kouilou River in Congo Republic (Ref. 81631) and Cuanza River in Angola (Ref. 28136, 54749, 120641).

Maturity: Lm ? range ? - ? cm
Max length : 15.3 cm TL jantan/; (Ref. 130826)
Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 14 - 18; Duri dubur: 0; Sirip dubur lunak: 17 - 21; vertebrata, bertulang belakang: 44 - 46. Diagnosis: Body moderate, often deep, its depth 25% of standard length or more; 13-17 pre-pelvic and 8-11 post-pelvic scutes, 1-2 scutes before pectoral fin origin, first pre-pectoral scute longer and more developed than following scutes without ascending arms; lower jaw strongly projecting, with strong canine teeth at symphysis; pre-maxilla with 2-4 strong backward-pointing canine teeth on each side behind outer row of pre-maxillary teeth; lower gillrakers 22-33, shorter than corresponding gill filaments; anal fin with 17-21 rays; silver stripe along flank (Ref. 188, 54749, 81269, 81631). It resembles Odaxothrissa mento, which has fewer gillrakers, 16-19 vs. 22-33; and Pellonula vorax, which lacks canine teeth in the upper jaw and has longer gillrakers, equal in length to gill filaments vs. shorter (Ref. 188, 54749).
Found in rivers and streams (Ref. 188), also in lagoons (Ref. 2849, 81269).
