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): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00712 - 0.03216), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (19 of 100).
