Lack of thorns along the midbelt of the disc from the level of the axils of the pectoral fins to the vicinity of the spiracles. Tails widen rearward toward the dorsal fins. No interspace between the bases of the dorsal fins. Upper surface pale brown, darker along posterior margins of disc, pelvic fins and tail. Dorsal fins and caudal black. Lower surface margined with black rearward from the level of the mouth (Ref. 6902).
