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: 41 - 43; 脊椎骨: 37 - 40. This species is distinguished from R. molossus by having fewer branched anal-fin rays (41-43, versus 43-47). It differs from R. itupiranga by having more anal-fin rays (41-43, versus 38-41), fewer scale rows between lateral line and anal-fin origin (15-16, versus 18-19) and fewer scale rows around caudal peduncle(27-28, versus 30-31).
這種被與 R. molossus 區分藉著具有較少數分枝的臀鰭棘條.(41-43, 對 43-47) 它有別於 R. itupiranga 藉著具有更多的臀鰭棘條 (41-43, 對 38-41), 尾柄的周圍在側線與臀鰭起源 (15-16, 對 18-19) 與較少的鱗片列之間的較少的鱗片列.(27-28, 對 30-31)
