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 - 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.
輕易地與另一個區分了本屬的二個種在臀鰭上藉著具有更多的分支條.(43-47, 對 41-43 在 R. ogilviei 中與 38-41 在 R. itupiranga 中) 鉤在 R. itupiranga 的雄性成魚標本的臀鰭上與在 R. ogilviei 的一個雄性成魚中出現但是有不被發現於可比較大小的 R. molossus 的雄性。
