Distinguished from its only congener Pareiorhina rudolphi by the following characters: anterior profile of head elliptical in dorsal view; snout sloping abruptly towards its tip in lateral profile; ventral border of rostral region and dorsal border of upper lip covered with odontodes; anterior ends of premaxillae and dentaries strongly sloped inwards; lower lip moderately developed and well separated from anterior margin of pectoral girdle; lower lip with a smooth, unpapillose band just behind the toothed portions of dentaries, which is especially conspicuous just behind the symphysis; anterior regions of roof and floor of mouth immediately behind premaxillae and dentaries, respectively, covered with rounded papillae; interorbital width 36.6-39.4% HL; postdorsal surface of trunk with a low, elongate ridge formed by 10-13 raised median unpaired plates; posteriormost 2-3 median plates without sensory pores of lateral line; inferior surfaces of first pectoral, pelvic and anal-fin rays covered by conspicuously pointed odontodes; and lower counts of body plates (25-27 dorsal plates; 17-22 mid-dorsal plates; 25-27 median plates; 18-20 mid-ventral plates; and 19-23 ventral plates) (Ref. 52873).
Inhabits stream with clear, cold and moderate to fast flowing water (Ref. 52873).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00374 - 0.01935), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
