Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 25 - 35; Épines anales: 0; Rayons mous anaux: 31 - 38. Diagnosis: dorsal fin between one half and twice the anal fin length; mouth inferior situated below the eyes (Ref. 28714). Body height > 25% of SL (Ref. 28714), 2.6-3.2 times in SL (Ref. 2915, 81274). Anal fin base 3.1-3.4 times in SL; caudal peduncle height 16.8-18.7 times in SL; eye diameter 3.5-4.5 times in head length; uniform silvery color (Ref. 2915, 81274). Upper jaw with 13-19, lower jaw with 22-29 teeth; subspecies P. b. bane has 29-34 rays in dorsal fin and 31-38 in anal while P. b. comoensis has a lower average number of rays, 25-30 in dorsal and 32-36 in anal fin; scale counts: 40-44 in a longitudinal line and 12 around caudal peduncle; ratio standard length/caudal-peduncle depth in P. b. comoensis: 17.0-18.0 (Ref. 81274). Coloration: uniform silvery (Ref. 2915, 81274).

Inhabits open water and vegetated areas of lakes, lagoons and irrigation canals; females grow larger and are more frequently caught than males (Sudan); chiefly insectivorous, feeding on the bottom and in vegetation (Ref. 28714). Affinities: P. ansorgii, differ only by the small eyes, the thick caudal peduncle, numerous teeth on lower jaw and the uniform silvery color (P. ansorgii has a spot on the dorsal fin).
