Morphology | Morphometrics
This species is distinguished from Nemacheilus hutjertjuensis [= Triplophysa hutjertjuensis] by the having the following characters: caudal fin from truncate to flangeate, never emarginate, as body length increases (vs. emarginate to truncate, never flangeate); a deep constriction at the middle, the anterior part usually larger than the posterior (vs. just in contrast generally); lips strongly wrinkled and with papillae (vs. weak and absent); dorsal base length 10.20 (8.36-11.80) in body length (vs. 8.17 (7.00-10.98)); even with the smallest depth at the origin, peduncle is straight and smooth (vs. inclined down backward, with that at the middle); vertebrae 4+34+1=39 (vs. 4+36-37+1=41-42;7); and a dark longitudinal stripe on the back, anterior to the dorsal, and the same one along the lateral line anteriorly and along the axis of body posteriorly (vs. a very narrow line on the back, quite clear, and a lot of maculates in two rows, one clear, along the lateral line and the body axis, and another, less clear, alongside it superiorly) (Ref. 118554).

Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00376 - 0.01926), b=3.04 (2.85 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
