背棘 (总数): 1; 背的软条 (总数): 6; 脊椎骨: 39 - 41. Body silvery, either without marking or with faint saddles. Fins, except caudal fin, blackened at least distally. Dorsal spine tip not reaching to adipose-fin origin when adpressed. Premaxilla with 2 rows of teeth. Adpressed anal fin fails to reach first lower procurrent caudal-fin rays. Mouth near snout tip; oral opening transverse, entirely ventral to nares; free lips absent. Anal fin with 4-6 simple rays, 10-12 branched rays. Differs from G. gagata in having its dorsal spine not reaching adipose-fin origin (versus reaching and even extending beyond adipose origin when dorsal-spine is depressed); smaller pelvic fin not reaching anal-fin origin (versus reaching anal-fin origin); last anal-fin ray not reaching first lower procurrent caudal-fin rays (versus extending posteriorly to origin of lower procurrent caudal-fin rays); complete bony encapsulation of the swim bladder (versus incomplete); and 2 rows of teeth on the premaxilla (versus 4 rows) (Ref. 40780).
身体银色的, 或没有印记或者有模糊的鞍状斑。 除了尾鳍之外的鳍末梢部地变黑的至少了。 背棘顶端不延伸到脂鳍起源 , 当紧贴的时候。 前颌骨有 2个列的齿。 紧贴的臀鳍无法达到第一个低的前流尾鳍鳍条。 在吻顶端附近的嘴; 口裂横跨的, 完全腹对鼻孔; 分离的唇不存在。 臀鳍有 4-6 单一的鳍条， 10-12 分支条。 有别于 G. gagata 有不被达成脂鳍起源的它的背棘;(对达到甚至延伸超过脂肪的起源当背棘被扁平的时候) 较小的腹鳍不达成臀鳍起源;(对达成臀鳍起源) 最后的臀鳍鳍条不达到第一个低的前流尾鳍鳍条;(对向后延伸对低前流的尾鳍鳍条的起源) 完成骨质封包的泳鳔;(对不完全的) 而且 2 列的牙齿在前颌骨 (对 4 列).(参考文献 40780)
