Pseudosinocyclocheilus is a monospecific genus of freshwater ray-finned fish belonging to the family Cyprinidae, the family which includes the carps, barbs, minnows and related fishes. The only species in the genus is Pseudosinocyclocheilus jinxiensis, a species of cavefish endemic to Xiaolong Spring in Jinxi County, Guangxi, China. In 2016, it was proposed that this species should be placed in its own genus Pseudosinocyclocheilus, a move subsequently supported by Catalog of Fishes and FishBase.
