Épines dorsales (Total) : 1; Rayons mous dorsaux (Total) : 7; Épines anales: 1; Rayons mous anaux: 3 - 4. This species differs from its congeners inhabiting the Río de La Plata and coastal basins of southern Brazil, except A. agostinhoi, A. multispinis, A. mullerae, A. taunayi and A. formoso, by possessing a maxillary barbel shorter and not free from its lower lip (vs. longer and free from lower lip); from the first 4 species, by the width of mandibulary teeth row 13.4-15.5% of HL (vs. 15.8-19.3%, 15.5-19.4%, 16.5-21.0% and 15.8-23.1%, respectively) and 32.9-37.9% of interorbital width (vs. 38.4-53.6%, 40.7-53.8%, 39.3-58.0% and 39.4-51.4%, respectively); from A. formoso by orbital diameter 11.9-15.3% of HL (vs. 8.3-8.7%), caudal peduncle depth 9.0-10.9% of SL (vs. 7.8-8.7%) and number of dentary teeth 40-68 (vs. 110) (Ref. 83296).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01479 (0.00633 - 0.03455), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
