Short description Morphology | Morphometrics

Dorsal soft rays (total): 5; Anal soft rays: 3 - 4. This species is distinguished from Pseudexostoma yunnanensis by the following characters: posterior margin of lower lip with 3 notches, depth of middle one shallower than lateral ones (vs. same depth), length of 2 smaller median lobes of lower lip longer than lateral lobes (vs. the same length); pelvic fin I, 3-4 (vs. I, 5); base of adipose fin longer, 37.8-45.1% SL (vs. 28.8-39.8); caudal peduncle more slender, depth 4.6-6.1% SL and 19.6-30.8% in length of caudal peduncle (vs. 6.4-8.3 and 32.6-42.7); premaxillary tooth band with 16-18 teeth (vs. 18-22), it is divided into 2 and are isolated (vs. connected partially). The species differs from P. brachysoma in having a longer pectoral fin 30.1-31.3% SL (vs. 24.9-29.8), pelvic 23.1-24.3% SL (16.1-22.9), and caudal 18-19.6% SL (vs. 13.6-17.9) fins; bigger eyes, diameter 8.2-10% HL (vs. 5.8-7.8) and wider interorbital width 25.5-30.8% HL (vs. 19.7-24.7) (Ref. 57980).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00260 - 0.01333), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±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):  Low vulnerability (10 of 100).
