Abstract: Two new Cypriniformes fish records from Yunnan Province, Carassioides acuminatus (collected from mainstream of Red River in Hekou County) and Hemimyzon pumilicorpora (collected from Gula River, Gula Town, Funing County, upper stream of the Pearl River drainage), were identified during fish specimen sorting at Kunming Institute of Zoology, Chinese Academy of Sciences. These two new records not only clarify the distribution patterns of the two species, but also enrich the knowledge of native fishes of Yunnan Province.
