Notes

The genus Acrossocheilus is restricted to southern China, northern Vietnam and northern Laos. It can be distinguished from related genera by the following combination of characters: rostral fold present; lips fleshy and continuous around corners of mouth; lower lip with a median interruption; mouth inferior; horny sheath on lower jaw; two pairs of barbels; last simple ray of dorsal fin osseous with a serrated or smooth posterior margin.

Members of the genus are characterised by possessing a particular number of dark vertical bar on each flank, and A. beijiangensis is one of only two species, the other being A. clivosius, to always possess 5 such bars.
