Differs further from other congeners by having the following combination of characters: gape short, the rictus falling short of the vertical through the posterior border of the posterior nares; 16 pectoral-fin rays; 164-186 anal-fin rays; anteroposterior length of premaxilla equal to the transverse width; length of the posterior ceratohyal approximately the same length as the ventral hypohyal; length of the coronomeckelian bone less than 20% the length of Meckel’s cartilage; teeth on the dentary restricted to the anterior one-half or slightly more of the dorsal margin of the dentary (Ref. 93148).
