Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 11; Anal soft rays: 7. Similar to Yunnanilus sichuanensis, Yunnanilus chui and Yunnanilus pulcherrimus. Distinguished from Yunnanilus sichuanensis by having 15-19 pored lateral line scales (vs. 10-12); caudal peduncle depth 9.75-11.89% in body length (vs. 7.54-8.72), 1.23-1.70 in length (vs. 0.9-1.09); and 10-12 square black spots on each side of the body (vs. 3 rows). Differs from Yunnanilus chui by the difference in stripes in males and females (vs. similar stripe in males and females) and by having 15-19 pored lateral line scales (vs. 2-4). Can be separated from Yunnanilus pulcherrimus by the difference in stripes in females and males (vs. similar stripes) and having 20-22 vertical bars on each side of the body (vs. 12-17) (Ref. 84761).

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 (0.00347 - 0.01512), 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

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
