Etymology: Oreochromis: Latin, aurum = gold + Greek, chromis = a fish, perhaps a perch (Ref. 45335); lepidurus: From the Greek "lepis" = scale and "oura" = tail, referring to the densely scaled caudal fin (Ref. 55074).

Africa: lower Congo River basin in Democratic Republic of the Congo (Ref. 2). Also reported from Angola (Ref. 2, 55074, 74387, 120641), where it probably occurs in the lower Congo River and/or coastal rivers between the lower Congo and Bengo (Ref. 2).

Espinhos dorsais (total) : 15 - 17; Raios dorsais (total) : 9 - 12; Espinhos anais: 3; Raios anais : 8 - 9; Vértebras: 28. Diagnosis: mature male with tuberculate genital papilla, some of the tubercles prolonged into filaments (Ref. 2). Caudal fin of adults densely scaled, usually with a reticulate melanin pattern (Ref. 2, 55074). 28 vertebrae; total dorsal rays 24-27; 19-24 lower gill-rakers; in adults snout long, preorbital bone deep and blade of lower pharyngeal 2-2.3 times the median length of the toothed area; outer teeth of jaws bicuspid unless by wearing down of minor cusp (Ref. 2).
Microphagous, using plankton (Ref. 2, 55074). Maternal, ovophilic mouthbrooder (Ref. 52307).

Estimates based on models
Índice de diversidade filogenética (Ref.
