背的软条 (总数) : 7; 臀鳍软条: 14 - 15; 脊椎骨: 40 - 43. Distinguished from all other species of Amblycipitidae by the following combination of characters: two patches of vomerine teeth; gill rakers 7-9; head large (head length 27.9%-34.9% SL; head depth 14.4-17.9% SL; and head width 22.4-29.4% SL; adipose fin low (4.6-6.0% SL); distance from dorsal origin to adipose origin short (25.7-32.0% SL); dorsal fin (21.2-24.9%SL), pectoral fin (18.4-20.7% SL) and pelvic fin (13.1-14.3% SL) long (Ref. 54505).
Body shape (shape guide): elongated.
与所有的其他种的 Amblycipitidae 区分了藉由跟随组合特征: 牦骨齿的二个区块; 鳃耙 7-9; 头部大的 (头长 27.9%-34.9% SL; 头部深度 14.4-17.9% SL; 而且头部宽度 22.4-29.4% SL; 脂鳍低的 (4.6-6.0% SL); 从背鳍起点到脂肪的起源短 (25.7-32.0% SL) 的距离; 背鳍 (21.2-24.9% SL) ，胸鳍 (18.4-20.7% SL) 与腹鳍 (13.1-14.3% SL) 长的.(参考文献 54505)
