Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 11; Raggi anali molli: 6; Vertebre: 31 - 32. Dorsum of head, body and paired fin bases with whitish reticulated or whitish spotted pattern; faint dark grey axial stripe covering three scale rows; skin around lateral line pores whitish; posterior part of pectoral fin with 5-7 faint annular bands; 20-21 branched pelvic fin rays; 49-54+2 lateral line scales; pelvic fin origin below dorsal fin origin; pectoral fin origin posterior to corner of mouth; pelvic fin reaching anal fin origin; small soft elevated patches of fine tubercles on first pectoral fin rays in males; tubercles on simple pectoral fin ray not enlarged; absence of cavity around mouth and absence of skin-fold between oropectoral membrane and ventral surface of head (Ref. 51729).

Inhabits rocky rapids and deep pools over sandy substrates. Also found in rocky pools isolated from the main river.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00603 (0.00256 - 0.01420), b=3.11 (2.90 - 3.32), 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

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