Graduate School of Chinese Academy of Sciences , Beijing 100049, China Abstract Isporisa baibungensis sp. nov. , from Xizang, China, is described and illustrated. It represents the first record of the genus Isporisa Walker from China. A diagnosis of the genus and a key to species of Isporisa are provided.
