简单描述
检索表 | 型态特徵 | 形态测量图
臀棘: 4 - 5; 臀鳍软条: 38 - 41; 脊椎骨: 39. Roestes itupiranga has fewer branched anal-fin rays (38-41) than R. molossus (43-47) and than R. ogilviei (41-43). Can be further distinguished from R. ogilviei by having more scale rows between lateral line and anal-fin origin (18-19, versus 15-16) and more scale rows around caudal peduncle (31-31, versus 27-28).
Body shape (shape guide): elongated.
Roestes itupiranga 超过 R. molossus(43-47) 与 R. ogilviei 有较少的分枝臀鳍棘条 (38-41) 。 (41-43) 可能是与进一步区分的 R. ogilviei 尾柄的周围藉着具有在侧线与臀鳍起源 (18-19, 对 15-16) 与更多的鳞片列之间的更多的鳞片列.(31-31, 对 27-28)
