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).
缺乏刺沿着来自胸鳍的枝腋高度到喷水孔附近的体盘的腰带中央。 尾部对于背鳍在背后扩大。 没有背鳍的基底之间的间隙。 上表皮白褐色, 比较深色的沿着体盘，腹鳍与尾部的后缘。 背鳍与尾鳍黑色。 下表面有黑色的边从嘴巴的高度向后.(参考文献 6902)
