简单描述

背的软条 (总数) : 11; 臀棘: 4 - 5; 臀鳍软条: 43 - 49; 脊椎骨: 38. In addition to the autapomorphic presence of a bony ridge on the lateral face of the second branchiostegal ray, this species can be separated from G. alatus in having more lateral line-scales (68-75, versus 58-59), more scale rows between lateral line and anal-fin origin (13-16, versus 9-12) and more scale rows around caudal peduncle(21-23, versus 19). It differs from G. maracaiboensis by its shorter pelvic fin (11.4-13.9% SL, versus 13.6-15.8) and the larger interorbital space (16.6-22.1% SL, versus 21.8-24.5).
Body shape (shape guide): fusiform / normal.
以及 autapomorphic 有在第二个鳃条骨的侧面上的一个骨脊, 这种能被与 G. alatus 分开有更多的侧线-鳞片 (68-75, 对 58-59), 尾柄的周围在侧线与臀鳍起源 (13-16, 对 9-12) 与更多的鳞片列之间的更多的鳞片列.(21-23, 对 19) 它用它的较短的腹鳍 (11.4-13.9% SL, 对 13.6-15.8) 与较大的眼间隔有别于 G. maracaiboensis 。 (16.6-22.1% SL, 对 21.8-24.5)
