Abstract

Yaoshania, new genus, is described with Protomyzon pachychilus as type species. Yaoshania is distinguished from othergenera of Balitoridae by its larger gill opening, a lip lamina at angle of mouth, and the rostral fold with four notches toaccommodate rostral barbels. A lectotype is designated for Y. pachychilus. Erromyzon kalotaenia, new species, is de-scribed from Guangxi, China. It is distinguished from other species of Erromyzon by the very reduced median lobe of therostral fold; the lower lip distinctly covered with melanophores; and the color pattern on the flank. A key to the species of Erromyzon is provided.
