Short description Identification keys | Morphology | Morphometrics

Can be easily diagnosed from most loricariids, except Megalancistrus, a few species of Chaetostoma, and some species of Pterygoplichthys and Delturus, by having high number of dorsal-fin branched rays (10-11). Can also be differentiated by having slightly evertible cheek plates (vs. fully evertible cheek plates of Chaetostoma, Megalancistrus, and most other Ancistrini and Pterygoplichthyini taxa; or absence of evertible cheek plates in Delturinae, Neoplecostominae, Hypoptopomatinae, Loricariinae, Corymbophanini and Rhinelepini). It further differs from Delturus by possessing four branched anal-fin rays (vs. five or six) and from several loricariids by having naked abdomen (vs. plated in e.g. Pterygoplichthys), snout almost completely plated leaving just a small naked area on its tip (vs. snout completely naked in e.g. Chaetostoma) (Ref. 75060).

Facultative air-breathing in the genus (Ref. 126274); Found in dark water stretches of rivers with rocky bottom, at altitudes from 50-662 meters above sea level (Ref. 75060).

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=0.01585 (0.00723 - 0.03476), b=2.96 (2.79 - 3.13), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
