Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine anali: 4 - 5; Raggi anali molli: 38 - 41; Vertebre: 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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00182 - 0.01257), b=3.13 (2.90 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 4.0 ±0.7 se; based on size and trophs of closest relatives
Resilienza (Ref.
