Rivibarbi

Diagnosis: Head pointed (Ref. 2940, 81282). Two pairs of moderately developed barbels, anterior pair may reach the anterior border of eye, posterior pair to the middle of eye; lateral line complete and horizontal; 22-27 scales in lateral line; 3.5 scales between lateral line and dorsal fin origin; 3.5 scales between lateral line and mid-belly; 2.5 scales between lateral line and pelvic-fin base; 12 scales around caudal peduncle; dorsal fin with slightly concave border; 8 branched dorsal fin rays; last simple dorsal-fin ray flexible and smooth on hind margin; no black spots; distinct black stripe in middle of sides and snout; dorsal fin colorless; maximum reported size 96 mm SL (Ref. 2940, 81282, 81639). Description: Medium-sized species (Ref. 81639). Dorsal profile slightly convex; pit-lines on head clearly visible (Ref. 81639). Dorsal fin with 3 unbranched and 8 branched rays; anal fin with 3 unbranched and 5 branched rays (Ref. 2940, 81282, 81639).Colouration: Typically a black longitudinal band on sides, extending forward unto gill cover; in some populations band may be heavily shaded, as in preserved specimens; lateral-line scales, as well as those on back and in first series below lateral line, black-edged; dorsal and caudal fins yellowish in life, anal fin orange, pectorals and pelvic fins yellowish (Ref. 2940, 81282, 81639, 122753).

Potamodromous. Migrating within streams, migratory in rivers, e.g. Saliminus, Moxostoma, Labeo. Migrations should be cyclical and predictable and cover more than 100 km.
