Diagnosis: body depth 3.9-6.2x and head length 3.4-4.7x SL; eye diameter 3.1-4.9x head length (Ref. 2940, 81282). Scale formula 9.5-11.5/48-64/4.5-6.5; 14-16 scales around caudal peduncle; 8 dorsal-fin branched rays; 13-15 anal-fin branched rays (Ref. 2940, 81282, 81639). Usually less than 15 vertical bars on sides; known from the large Nilo-Sudanese basins (Ref. 2940, 81282). Round spot on caudal peduncle (Ref. 81639). Description: mouth terminal, without barbels; scales with divergent striae; dorsal fin falciform, originating in advance of anal fin; caudal fin forked (Ref. 81639). D: III,8; A: III,13-15; P: 14-16; V: I,8 (Ref. 2940, 81282, 81639). Gill rakers short (Ref. 2940, 81282). Coloration: live specimens silvery with greyish green back; sides marked with 12-15 black vertical bars becoming progressively lower posteriorly (Ref. 2940, 81282, 81639). Intermediate spots or bars may be present in anterior part of body; orange-colored fins in life (Ref. 2940, 81282). |
