| Diagnosis |
Body deep, with depth at dorsal-fin origin 28.7-37.1% SL and depth at pectoral-fin insertion 32.2-39.3. Distinguished easily from its congeners by the extensive scaling over the caudal and anal fins. Differs from elongate-bodied Triportheus species that have 1 longitudinal scale row between the pectoral-fin insertion and the ventral keel by the presence of 2 longitudinal scale rows between the pectoral-fin insertion and the ventral keel. Differs further from deep-bodied congeners by the combination of the number of hill rakers on the lower limb of the first gill arch (24-28); the number of branched anal-fin rays (28-32); and the number of lateral-line scales (34-39) (Ref. 54769). Description: D. ii,9; A. iii,28-32; P. i,10-13; V. i,6 (Ref. 54769). |
