Short description Identification keys | Morphology | Morphometrics

Can be diagnosed from its congeners by having the following characters: breast scaled between pectorals, scales extending forward beyond pectoral base (at least in some individuals of any population); snout length greater than postorbital distance; barbel reaching behind center of eye, its length 25-34% HL, 1.2-1.8 times in snout length; head length 26-28% SL; head depth 12-17% SL at nape, 48-54% HL at eye; body depth 22-25% SL; head width 16-18% SL, 60-69% HL; eye diameter 5-6% SL, 2.7-3.4 times in head depth, 1.4-1.7 times in interorbital distance (at 7-10 cm SL); caudal peduncle depth 34-42% HL (Ref. 59043).

Biology     Glossary (e.g. epibenthic)

Occurs only in the upper and middle stretch of a small, slowly flowing stream. Attains up to about 10 cm SL (Ref. 59043).

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=0.00724 (0.00385 - 0.01363), b=3.16 (3.00 - 3.32), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 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).
