Short description Identification keys | Morphology | Morphometrics

Diagnosed from all species of Hypostomus, except H. levis, by lacking adipose fin. Differs from H. levis mainly by having bifid teeth, with mesial cusp large and rounded, and lateral cusp small and pointed; 23-42 premaxillary and 25-42 dentary teeth; black spots on body. Can be separated from all species of Hypostomus in the La Plata basin (except H. ancistroides, H. angipinnatus, H. aspilogaster, H. borellii, H. boulengeri, H. brevis, H. commersoni, H. cordovae, H. denticulatus, H. dlouhyi, H. fluviatilis, H. heraldoi, H. hermanni, H. isbrueckeri, H. laplatae, H. latifrons, H. mutucae, H. nigromaculatus, H. peckoltoides, H. piratatu, H. topavae, H. uruguayensis, and H. variostictus) by the presence of darker spot on body.

Facultative air-breathing in the genus (Ref. 126274)

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=0.01230 (0.00531 - 0.02848), b=2.97 (2.76 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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