Etymology: Rhyacoglanis: From the Greek words 'rhyax' (torrent) and 'glanis' (catfish), indicating a catfish inhabiting running waters in reference to its habitat (Ref. 128485); annulatus: Species name is a Latin adjective meaning ringed, in reference to the caudal-peduncle band with a light inner region (Ref. 128485).

Short description Chiavi di identificazione | Morfologia | Morfometria

Vertebre: 34 - 35. This species can be distinguished from congeners by the presence of caudal-peduncle band with an unpigmented central region (vs. band uniformly dark), and a larger distance between anus and anal-fin origin (Ref. 128485).

A rheophilic species, prefer rapids and other swift-flowing waters. Possibly rare, known only from two preserved specimens collected in widely separated areas from the southern portions of the Rio Orinoco basin (Ref. 128485).

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
