A new species and a new record species are described： H. （s. str. ） yonnanensis sp. nov. and H. （s. str. ） vittigera Sasakawa, 2001. The types are deposited in the Entomological Museum of China Agricultural University, Beijing. Homoneura （ s. sir. ） yunnanensis sp. nov. （Figs. 1- 6） The new species is somewhat similar to H. （ s. str.） fascivertris Malloch, 1927 from Taiwan in the wing pattern and general coloration, but it can be separated from the latter by the first flagellomere black with the yellow apex and the aedeagus with the acute processes at middle and apex. In H. （ s. str. ） fascivertris, the first fiagellomere has the yellow base and the aedeagus has no acute process.
