| Diagnosis |
A member of the group of species with complete or nearly complete lateral line, 8 1/2 branched dorsal rays, 9+8 branched caudal rays and no sexual dimorphism. Can be distinguished by the following characters: 13-14 bars on body, the anterior ones not conspicuously wider than posterior ones; maximum head width 16.6-17.4% SL; eye diameter 3.1-3.6% SL, 14-17% HL; interorbital width 7.3-7.8% SL, 35-36% HL (Ref. 39226). Its slender caudal peduncle (1.23-1.53 times longer than deep) and its color pattern distinguish it from any congener (Ref. 39226). Presence of a dark blotch at dorsal-fin origin; a faint blotch at base of posterior rays of dorsal fin; scales very sparse or absent in front of dorsal fin and on belly (Ref. 12693). |
