背棘 (总数) : 1; 背的软条 (总数) : 4 - 5; 臀棘: 0; 臀鳍软条: 9; 脊椎骨: 44 - 45. Differentiated from its congeners by the following unique set of characters: eye diameter 1.9-3.2% HL; interorbital distance 19.2-25.1% HL; snout length 28.6-34.1% HL; length of caudal peduncle 33.7-36.5% SL; 44-45 vertebrae; and brown spots on the dorsal and pectoral fins concentrated in a dark band in the distal half (Ref. 45707).
用特徵的下列独特组与它的同类区别了: 眼直径 1.9-3.2% HL; 眼间距 19.2-25.1% HL; 吻的长度 28.6-34.1% HL; 尾柄 33.7-36.5% SL 的长度; 44-45个脊椎骨; 而且在背部与胸鳍上的褐色斑点在末梢部的一半中集中在一个深色条纹了.(参考文献 45707)
