简单描述
型态特徵 | 形态测量图
背的软条 (总数): 11; 臀棘 4-5; 臀鳍软条: 43 - 47; 脊椎骨: 40. Readily distinguished from the other two species of the genus by having more branched rays on the anal fin (43-47, versus 41-43 in R. ogilviei and 38-41 in R. itupiranga). Hooks are present on the anal fin of adult male specimens of R. itupiranga and in one adult male of R. ogilviei but have not been found in males of R. molossus of comparable sizes.
轻易地与另一个区分了本属的二个种在臀鳍上藉着具有更多的分支条.(43-47, 对 41-43 在 R. ogilviei 中与 38-41 在 R. itupiranga 中) 钩在 R. itupiranga 的雄性成鱼标本的臀鳍上与在 R. ogilviei 的一个雄性成鱼中出现但是有不被发现于可比较大小的 R. molossus 的雄性。
