Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 6; Anal soft rays: 8; Vertebrae: 46 - 47. Distinguished with the following three apomorphic anatomical complexes: 1.) mouth ventral and transverse, supported by reoriented, much expanded premaxillae and foreshortened mandibles; premaxillae and dentaries densely covered with robust, needle-like teeth arranged in a steeply-descending, antero-posterior size series. 2.) lateral margins of orbit and otic region elevated with textured ridges developed from the frontal, sphenotic and pterotic bones surrounding the supraorbital, otic and postotic lateralis sensory canals. 3.) Interorbital septum severely compressed as thin, apparently median, bony sheet. Among Pimelodidae, it shares apomorphic features, placing it near the diverse Calophysus-Pimelodus clade (Ref. 83450).

Collected from large rivers with swift currents and bedrock to boulder-strewn substrates (Ref. 83450).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00145 - 0.01438), b=3.08 (2.83 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.7 se; based on size and trophs of closest relatives

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).
