背的软条 (总数) : 13; 脊椎骨: 35. Differs from other species of the genus by the combination of the following characters: long pectoral fins always surpassing pelvic-fin origin; anal fin origin at level of a vertical through fifth or sixth dorsal fin rays; one supraopercular and two humeral spots on flanks; two or three maxillary teeth; 35-38 perforated scales in the lateral series; and 24-27 branched anal fin rays. Distinguishes further from most of its congeners by having deep body (36.9-42.6% SL); large eye (10.2-11.9% SL); maxillary length, 100.0-136.6% interorbital width); and presence of 24-25 gill rakers on first branchial arch (Ref. 55798).
有别于其他本属的种藉由下列特征的组合: 长的胸鳍总是胜过的腹鳍起点; 在水平的臀鳍起源一垂直的经过第五的或第六个背鳍鳍条; 一鳃盖上方的与在侧面上的二个肩部的斑点; 二或三个上颚齿; 在侧线列中的 35-38个有排孔的鳞片; 而且 24-27个分枝的臀鳍棘条。 区别进一步从大部分的它的同类借着具有深的身体 (36.9-42.6% SL); 大的眼 (10.2-11.9% SL); 上颌骨长度, 100.0-136.6% 眼间骨宽度); 而且在第一个鳃弓上有 24-25个鳃耙.(参考文献 55798)
