Short description Morphology | Morphometrics

This species is distinguished from its congeners by the following set of characters: presence of both rostral and maxillary barbels; last simple dorsal ray weak and smooth; complete lateral line with 41+1 pored scales; scales in transverse line from dorsal-fin origin to pelvic fin origin 9/1/4; scales between lateral line and anal-fin origin 5½; gill rakers long and branched; proximal end of fifth ceratobranchial hook-shaped, with 5+3+2 teeth; presence of a black bar behind the opercle (Ref. 94728).

Biology     Glossary (e.g. epibenthic)

Inhabits deeper part of clear fast flowing large jungle streams and rivers in upland areas (Ref. 41236).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00308 - 0.01353), b=3.09 (2.91 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Very high vulnerability (83 of 100) .
