型態特徵 | 形態測量圖
臀鰭軟條: 18 - 22; 脊椎骨: 50 - 54. Distinguished from its congeners by the following characters: caudal fin deeply forked; outer, unbranched principal rays of upper and lower lobes longest in each lobe and about equal in length; posterior fontanelle elongate, forming conspicuous groove on supraoccipital bone, skin pigmented black in groove (vs. congeners which are without elongate posterior fontanelle, supraoccipital groove, or black pigment); unique in having combination of elongate body and broad-shaped head (vs. congeners with either elongate body and head, or stout body with broad head) (Ref, 57983).
與它的同類區分了藉由跟隨特徵: 尾鰭深深地分岔; 外部的, 上葉與下葉的不分枝主要鰭條長的在每個葉中大約長度相等; 在後部的囪門延長, 形成在上枕骨硬骨上的顯著的凹槽, 皮膚有顏色黑色的有凹槽;(沒有細長的在後部的囪門，上枕骨凹槽或黑色素 vs. 同類那是) 獨特的有細長的身體和寬-形狀的頭部 (vs. 同類具有或細長的身體與頭部 , 或矮胖的身體有寬的頭部) 的組合.(參考文獻, 57983)
