簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 11; 臀棘 4-5; 臀鰭軟條: 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).
以及 autapomorphic 有在第二個鰓條骨的側面上的一個骨脊, 這種能被與 G. alatus 分開有更多的側線-鱗片 (68-75, 對 58-59), 尾柄的周圍在側線與臀鰭起源 (13-16, 對 9-12) 與更多的鱗片列之間的更多的鱗片列.(21-23, 對 19) 它用它的較短的腹鰭 (11.4-13.9% SL, 對 13.6-15.8) 與較大的眼間隔有別於 G. maracaiboensis 。 (16.6-22.1% SL, 對 21.8-24.5)
