Short description Identification keys | Morphology | Morphometrics
Differs from all congeneric species by the combination of the following characters: premaxilla with 4-6 teeth on the outer row, teeth aligned and tricuspidate or tetracuspidate, maxillary teeth 3-4 and usually pentacuspidate, 18-21 branched anal-fin rays, lateral line with 36-38 perforated scales, a short peduncle (11.6-13.3% SL), a ventrally elongated black humeral spot, a very faint second humeral spot and a narrow black lateral band (Ref. 52417).
Collection sites have rapids with clear flowing water, pools and some areas of slow current. Bottom substrate includes mud, sand and mostly stones. Water depth ranges from 0.40-2m and temperate of the water near surface during summer is about 26° C (Ref. 52417).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00407 - 0.02241), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 2.6 ±0.3 se; based on size and trophs of closest relatives
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).
