简单描述 型态特徵 | 形态测量图

背的软条 (总数): 6-7; 臀鳍软条: 4; 脊椎骨: 18 - 20. No tubercles in skin covering eyeballs and on ventral surface of disk except a few near bases of pelvic fins. Interorbital and mouth both exceptionally narrow. Conspicuous chalk-white oval marking on midline of lower jaw. Teeth present on palatines and vomer. Cephalic lateral-line counts: subopercular usually 6; preopercular 2.
