Gagata melanopterus Roberts & Ferraris 1998

Body silvery, either without marking or with faint saddles. Fins, except caudal fin, blackened at least distally. Dorsal spine tip not reaching to adipose-fin origin when adpressed. Premaxilla with 2 rows of teeth. Adpressed anal fin fails to reach first lower procurrent caudal-fin rays. Mouth near snout tip; oral opening transverse, entirely ventral to nares; free lips absent. Anal fin with 4-6 simple rays, 10-12 branched rays. Differs from G. gagata in having its dorsal spine not reaching adipose-fin origin (versus reaching and even extending beyond adipose origin when dorsal-spine is depressed); smaller pelvic fin not reaching anal-fin origin (versus reaching anal-fin origin); last anal-fin ray not reaching first lower procurrent caudal-fin rays (versus extending posteriorly to origin of lower procurrent caudal-fin rays); complete bony encapsulation of the swim bladder (versus incomplete); and 2 rows of teeth on the premaxilla (versus 4 rows) (Ref. 40780).

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Vertebrae: 39 - 41

Found in larger river with muddy bottoms (Ref. 94495).
