简单描述
型态特徵 | 形态测量图
This species is distinguished by the following characters: dorsal disc with a prominent mid-scapular thorn and dermal denticles which are small, spinular, partly embedded and are restricted to the snout, supraorbital, interorbital and mid-lumbar regions and midline of the tail; nasal capsules are oval, relatively broad and short; the ischiopubic bar of pelvic girdle is strongly arched with concave outer anterior margin, short angular prepelvic process and long posterior mesial process (Ref. 113541).
接近圆形的体盘; 非常长的尾部, postcoacal 长度超过 90% 的体盘长度; 非常小的眼, 大约 16% 的吻与 8% 的头长; 宽又软骨的眼窝超过 5% 全长; 鼻间盖矩形的; 没有在后侧的边缘上的宽的叶; 喷水孔的内缘斜角; 小的刺与小刺在背面上; 侧面的尾部摺叠不发达的; 没有背鳍; 腹鳍非常短与宽的, 顶点略微有角的; 尾鳍非常低的与延长, 上尾叶长度超过 9 倍鳍高; 89个胸鳍动脉.(参考文献 51067)
