Dorsale zachte stralen (totaal) : 11; Anale zachte stralen: 18 - 20. This species is distinguished from all its congeners from Rio Iguaçu by the following set of characters: third infraorbital narrow and deep, not in contact with preopercle, leaving an ample naked area between these bones; teeth of premaxillary series straight; symphysal teeth of premaxillary internal series and dentary teeth tricuspid; teeth on premaxillary external series often tricuspid, with lateral cusps minute when pentacuspid; rest of teeth in premaxillary internal series pentacuspid; maxillary bone long, forming an obtuse angle with premaxillary bone when mouth is closed; dentary large and provided with 4 large tricuspidate, followed by 3-5 tricuspid or pentacuspid teeth (Ref. 85756).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 2.8 ±0.4 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
