Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 10. Diagnosis: fronto-parietal fontanel absent in adults, sometimes pore-like in juveniles; snout short, more than 3x head lenght; dorsal fin origin just behind pelvic fin insertion; sexual dimorphism affecting anal fin shape; head length/snout length 3.1-4.0; 24-30 lateral line scales; 4.5 scales between lateral line and dorsal fin; 10.5-12 predorsal scales; 12-16 anal fin branched rays; 16-25 gill rakers on lower limb of first gill arch; 8 teeth in outer premaxillary row; adults medium-sized; humeral spot always present; broad black band on flanks; most apparent part of this band reaches or extends beyond vertical through posterior base of dorsal fin (Ref. 80290).

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=0.01122 (0.00496 - 0.02540), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

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