An “albipinna group” plunderfish. Body elongate, flattened ventrally, with a large and wide head. Post-temporal ridges not developed. Eyes large. Snout flattened; length equal to orbit. Interorbital wide. Two dorsal fins: one a very small spiny fin over opercle and the other a long-based fin consisting of rays. Second dorsal fairly low. Anal fin short in height with origin well behind dorsal origin. Pectoral fin large and fan-shaped. Pelvic fin jugular, rounded and fairly long. Caudal fin rounded. Mouth reaching beyond middle or orbit; protractile. Jaws with small teeth. No teeth on vomer or palate. Upper opercular edge with a pointed, hook-like projection. Body naked. Two lateral lines: one on the upper body ending under the posterior dorsal fin and the other on the lateral midline on the rear body and caudal peduncle. Mental barbel very long (1.6 in HL) with terminal extension twice as wide as stalk (length 40% of TL of barbel). Terminal extension with rounded papillae.
