Diagnosis

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).
