Distinguished from its congeners by a unique combination of characters: two unpaired median pre-dorsal plates, body width 10.0-13.0% of post-dorsal fin length, inter-orbital distance between 10.6-13.0% of post-dorsal fin length, inter-orbital distance between 25.0-29.0% of eye-to-dorsal fin length; low number of jaw teeth (12-15 teeth in upper left jaw, 9-13 in lower left jaw), and pre-dorsal fin body pigmentation not formed into distinct lines between longitudinal rows of odontodes (Ref. 54475).
与一个独特组合特征的它的同类区分了: 二个不成对的中央前背部的碟, 身体宽度 10.0-13.0% 的在背鳍之后的长度, 在中间-眼窝的 10.6-13.0% 的在背鳍之后的长度之间的距离, 在中间-眼窝的 25.0-29.0% 的眼之间的距离-到-背鳍长度; 颌齿 (12- 在上面的左边颌中的 15个齿, 在低的左边颌中的 9-13) 的低数字 , 与不在纵列的齿之间的形成明显的线的前背鳍身体颜色.(参考文献 54475)
