背的軟條 (總數) : 10 - 11; 臀鰭軟條: 49 - 53. Fewer lateral line scales (58-59, versus 64-70 in G. maracaiboensis and 68-75 in G. atratoensis), fewer scale rows between lateral line and anal-fin origin (9-11, versus 12-14 in G. maracaiboensis and 13-16 in G. atratoensis) and fewer scale rows around caudal peduncle (19, versus 21-23 in G. maracaiboensis and 21-23 in G. atratoensis).
較少的側線鱗片 (58-59, 對 64-70 在 G. maracaiboensis 與 68-75 在 G. atratoensis), 在側線與臀鰭起源 (9-11, 對 12-14 在 G. maracaiboensis 與 13-16 在 G. atratoensis) 與較少的鱗片之間的較少的鱗片列尾柄的周圍列.(19, 對 21-23 在 G. maracaiboensis 與 21-23 在 G. atratoensis)
