背棘 (總數) : 1; 背的軟條 (總數) : 7; 臀鰭軟條: 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).
與同類區分了, 除 花鰭鮠〔Leiocassis poecilopterus〕 , 有對頸背的碟感到接觸在一起的上枕骨突起的後面的頂端。 進一步在持有一個較深的身體方面有別於 L. micropogon;(19.8-20.8% SL vs.10.0-18.9) 而且從 L. poecilopterus 在有一個方面比較長的脂鰭 (15.8-16.6% SL vs.12.9-15.0) 與更長的背部 (20.8% SL vs.15.5-18.4) 與胸棘 (17.9-18.7% SL vs.14.5-17.5).(參考文獻 55439)
