Snout moderately long, broadly parabolic, preoral snout equal or somewhat greater than mouth width but shorter than distance from mouth to pectoral origins;

upper anterolateral teeth with semioblique or oblique cusps.

First dorsal fin very low and long; second dorsal moderately large, nearly as high or slightly higher than first, with base about 1/2 to 3/5 length of first dorsal base, and spine origin over inner margins of pelvic fins; distance from first dorsal insertion to origin of second dorsal spine about as long as tip of snout to pectoral midbases in adults and subadults; free rear tips of pectoral fins formed into narrow, angular and elongated lobes that reach well beyond the level of first dorsal spine, inner margins slightly shorter than distance from second dorsal spine to caudal origin; caudal fin with a shallowly concave to weakly notched posterior margin in adults and subadults.

Lateral trunk denticles not overlapping each other, blocklike, with crowns sessile on bases and without pedicels, crowns elongated and longitudinally rhomboidal in adults, with a strong main cusp and no lateral cusps on their posterior edges in adults.
