Diagnosis

Distinguished by the following combination of characters: gape relatively long, the rictus falling short posteriorly of the vertical through the posterior naris; the anteroposterior length of premaxilla equal to the transverse width; teeth on the dentary occupying most of the dorsal margin; two or three teeth arranged in a single row on the internal surface of the endopterygoid; 15-17 scales above the lateral line at the midbody; the length of the coronomeckelian bone less than 20% the length of Meckel’s cartilage; length of the

posterior ceratohyal 1.5 times the length of the ventral hypohyal; the length of the caudal filament 16.0-25.7% LEA; depth of the caudal filament 5.6-11.2% CL; presence of a narrow dark stripe along the lateral line and a broad band of dusky to dark pigmentation overlying the basal pterygiophores of the anal fin; 19-21 pectoral-fin rays; 205-228 anal-fin rays; head

length at the opercle 13.5-14.7% LEA (Ref. 93148).

Description: anal fin with 22-33 unbranched rays and 205-228 total fin rays; pectoral-fin rays ii, 19 to ii, 21 (Ref. 93148).
