Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 7; Anal soft rays: 5. This species can be distinguished from its congeners by the following set of characters: abdomen completely covered with small to medium-sized, irregularly shaped plates; area in front of gill opening without plates, ventrally; head with straight sides; and head and caudal peduncle narrower. Colouration: color pattern of dorsal body is uniform light brown without transversal dark bands, mostly in the caudal peduncle (Ref. 128488).

Inhabits rivers and flooded areas at altitudes 135 to 334 m asl, in areas with gentle slope and sandy or clay bottoms (Ref. 128488).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00347 (0.00159 - 0.00757), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.4 ±0.2 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).
