Through photomicrographic technique，the 50 samples collected from the Kanas Nature Reserve Xinjiang in July 2016 were identificated. The results showed that there were five taxa of desmids as new records in China，which belonged to 3 genera. They were Cosmarium cyclicum Lundell，Cosmarium subochthodes var.majus Schmidle，Euastrum verrucosum var. alpinum （HuberPestalozzi） Krieger， Micrasterias americana (Ehrenberg) Ralfs，and Micrasterias americana var.boldtii Gütwinski. In addition，the species identification character and circumstances were described in detail. These new records would enrich the study data of desmids in Xinjiang.
