Etymology: Pseudancistrus: Greek, pseudes = false + Greek, agkistron = hook (Ref. 45335).

Ecologia
; acqua dolce demersale; pH range: 6.1 - 6.2. Tropical; 25°C - 26°C (Ref. 90183)

Size / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.4 cm SL maschio/sesso non determinato; (Ref. 36713)
Facultative air-breathing in the genus (Ref. 126274); The smallest among the Guianese Lasiancistrus since it hardly reaches 10 cm TL. Prefers the rapid zones where the depth is shallow, the substrate is rocky and the illumination is moderate. Found in association with Lasiancistrus brevispinis, Cteniloricaria fowleri, Ancistrus aff. temminckii and Genicichla ternetzi. Its small size, odd shape and bright coloration make this species especially interesting for aquarists (Ref. 35381).

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 (10 of 100).
