Teleostei (teleosts) > Siluriformes (Catfishes) > Loricariidae (Armored catfishes) > Hypostominae
Etymology: Pseudancistrus: Greek, pseudes = false + Greek, agkistron = hook (Ref. 45335); pectegenitor: Derived from the Latin pecten (quill) and genitor (father), in reference to the hypertrophied odontodes of the snout, pectoral spine and evertible cheek plates, and the fact that one presumably adult male was collected while caring large brood of young.

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=0.01549 (0.00719 - 0.03336), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-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 (19 of 100).
