Short description Identification keys | Morphology | Morphometrics

This species can be distinguished from its congeners by the presence of thin light vertical bands on the truck, sometimes incomplete (vs. plain, with black or white spots, or unpigmented body. It differs from other Ancistrus species from the rio Madeira basin by the following set of characters: pectoral-fin length exceeds the pelvic-fin origin (vs. not reaching or just reaching the pelvic-fin origin in A. marcapatae, A. megalostomus and A. montanus); larger cleithral width 33.5-36.9% in SL (vs. 27.7-33.0% in A. montanus); reduced dentary width 45.3-54.4% in interorbital distance (vs. 64.6-86.6% in A. marcapatae and 64.9-91.4% in A. melagostomus); and presence of an adipose-fin (vs. absent in A. verecundus) (Ref. 128813).

Found in small streams (Ref. 128813).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01318 (0.00580 - 0.02997), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

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).
