Morphology | Morphometrics
Vertebrae: 33. Distinguished from other species of the genus Yunnanilus by the unique color pattern and the elongated papillae on upper and lower lips. Differs from closely related species Yunnanilus pleurotaenia by the following morphometric characters: standard length/body depth 4 .3-5.6 vs. 3.9-4.9; standard length/head length 4.4-5.1 vs. 3.7-3.9; standard length/caudal-peduncle length 5.7-7.1 vs. 7.7-9.1; head length/snout length 2.7-3.5 vs. 2.5-2.8; caudal-peduncle length/depth 1.2-1.7 vs. 1.1-1.2 (Ref. 76753).
Inhabits underground river (Ref. 76753).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00308 - 0.01417), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±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 (15 of 100) .
