Espinhos dorsais (total) : 7; Raios dorsais (total) : 8 - 10; Espinhos anais: 1; Raios anais : 7 - 9; Vértebras: 27. This species is distinguished from all its congeners except R. szechuanensis by the following set of characters:no sensory canals and sensory pores on head; cheeks and operculum, no spots or stripes; it differs from R. szechuanensis with the second dorsal fin with 9-11, longitudinal rows of inverted V-shaped or dash-like brown markings (vs. with blue spots, some coalescing into vertical bars), incomplete brownish edges on flank scales below
second dorsal fin (vs. complete edges), and a bright-yellow branchiostegal membrane (vs. white or blue) (Ref. 138923).
Body shape (shape guide): elongated; Cross section: oval.
This species occurs in pebble-bottomed sections of cold, flowing rivers. It is in sympatry with Acheilognathus mengyangensis, Gobiocypris rarus, Yunnanilus jiuchiensis, Opsariichthys chengtui and Belligobio pengxianensis.
