Abstract
Two new cixiid planthopper species: Andixius longispinus Zhi & Chen, sp. n. and A. trifurcus Zhi & Chen, sp. n. are described and illustrated from China (Yunnan Province) to provide the genus with four species in total. The generic characteristics are redefined. A key based on male genitalia to the four known species of this genus and a map of their geographic distributions are provided.
