Distinguished from all other species of the genus by the combination of the following characters: gill rakers on the first arch 18-20; branched anal-fin rays 48-50; length of accessory premaxillary tooth patch extending posteriorly nearly to the terminus of the gape; posterior limit of the upper jaw under the orbit; fleshy flap along the anterior margin of the posterior naris barely extending medial of the medial margin of the naris for a distance distinctly less than the transverse length of the posterior naris; pectoral-fin spine length 18.7-21.3% SL: lateral margin of the pectoral spine smooth; and snout in lateral view rounded (Ref. 75095). Description: D II,7; A v,48 - v,50; P I,15 - 1,16; V i+5 (Ref. 75095). |
