Short description Identification keys | Morphology | Morphometrics
This species is distinguished by the following characters: a well-developed, pendulous and conspicuously arched rostral fold, with an entirely crenulated margin; prominent papillae densely covering the margin of the rostral fold and the anterior part of the lower lip; long postlabial grooves, partitioning the lower lip into three parts; left dentary is shaped like an inverted L in ventral view (right dentary is a mirror image), with the transverse branch longer than half the length of the longitudinal branch; stubby lateral process at the anterolateral margin of the longitudinal branch, close to the corner; upper jaw, the premaxilla bears a triangular ascending process tapering to a point; maxilla with a pair of articular heads at the anterodorsal margin, a distinct fingerlike descending process posterior to the medial articular head embracing the ascending process of the premaxilla; three rows of teeth on the pharyngeal bone (= ceratobranchial 5); teeth are coarsely compressed; dentition formula was variable among the three examined specimens: 2.4.5-6.4.2 in holotype KIZ2012003910, 2.4.4-5.4.2 in paratype KIZ2012003911, and 2.4.5-5.4.2 in paratype KIZ2012005694; main row on the right ceratobranchial 5 had six teeth in the holotype, but four on the left side of one of the paratypes (Ref. 128942).
Found in a karst cave outlet and connected stream, at 1-2 m depth. Sympatric with Balitora ludongensis, Cophecheilus bamen, Prolixicheilus longisulcus, Rectoris longibarbus and Yunnanilus jinxiensis (Ref. 128942).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
