Morphology | Morphometrics
Differs from any other Chinese Schistura loaches by the following combination of characters: color pattern consisting of 8-12 dark brown bars, absence of scales and presence of median notch in lower jaw. Distinguished from the closely related S. fasciolata
by: absence of scales on body (vs. scaled body); exoccipital fenestra seen from lateral view only); 7-8 vertebrate between the Weberian apparatus and first proximal radial of dorsal fin (vs. 9-10) (Ref. 7410).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00270 - 0.01543), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±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.).
Vulnerability (Ref. 59153
): Low vulnerability (20 of 100) .
