Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 6; Raggi anali molli: 11 - 13; Vertebre: 51 - 52. This species is distinguished by the following characters: a small serrae on the anterior proximal margin of first pectoral-fin ray; anal-fin rays iv-v, 11-13 (15-17 total); adipose-fin base relatively short (40.9-47.4% SL); small eyes (7.4-14.2% HL); adipose fin is confluent to caudal fin; maxillary barbel not reaching pectoral-fin base in adults and reaching or scarcely surpassing first pectoral-fin ray in small juveniles (Ref. 86258).

Biologia     Glossario (es. epibenthic)

This species inhabits well-oxygenated rivers and streams, with gravel substratum and moderate to rapid flowing waters. Individuals usually shelter under large rocks. Apparently solitary and only a few specimens are usually captured per collecting site (Ref. 86258).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00362 - 0.01664), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
