背棘 (总数) : 1; 背的软条 (总数) : 7; 臀鳍软条: 14; 脊椎骨: 38 - 39. Distinguished from congeners, except Leiocassis poecilopterus, in having the posterior tip of the supraoccipital process in contact with the nuchal plate. Further differs from L. micropogon in possessing a deeper body (19.8-20.8% SL vs. 10.0-18.9); and from L. poecilopterus in having a longer adipose fin (15.8-16.6% SL vs. 12.9-15.0) and longer dorsal (20.8% SL vs. 15.5-18.4) and pectoral spines (17.9-18.7 % SL vs. 14.5-17.5) (Ref. 55439).
与同类区分了, 除 花鳍鮠〔Leiocassis poecilopterus〕 , 有对颈背的碟感到接触在一起的上枕骨突起的后面的顶端。 进一步在持有一个较深的身体方面有别于 L. micropogon;(19.8-20.8% SL vs.10.0-18.9) 而且从 L. poecilopterus 在有一个方面比较长的脂鳍 (15.8-16.6% SL vs.12.9-15.0) 与更长的背部 (20.8% SL vs.15.5-18.4) 与胸棘 (17.9-18.7% SL vs.14.5-17.5).(參考文獻 55439)
