Maturity: Lm ?  range ? - ? cm
Max length : 15.9 cm SL самец/пол неопределен; (Ref. 36713)
Facultative air-breathing in the genus (Ref. 126274); Not so frequently occurring. Caught in rapid zones where Pseudancistrus barbatus lives although nothing is known of the ecological relationship between the two species. The odontodes on the extreme end of its snout and its pectoral spines are very well developed (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).
устойчивость к внешним воздействиям (Ref.
120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
