The following new taxa from China are described in the tribe Fenusini: Zhengi na megamma gen. et sp. nov., Messa nigrotegula sp- nov. 9 Parna vestigndis sp. nov., Parna distincta sp. nov. , Sinofenusa lui gen et sp. nov., Profenusa xanthocephala sp. nov..Anafeausa acericola (Xiao, 1992 ) comb. nov. is transferred from Messa. The genus Parafenusa Zhelochovtsev (1976 ) is synonymized with Afusa Malaise (1964), which is reestablished as a distinct genus and removed from the synonymy of Nefsa Ross. Following new combinations are established: Afusa cerasi (Zhelochovtsev) comb. nov. and Afusa pruni (Zhelochovtsev) comb. nov., both transferred from Parafenusa; Afusa maharibiana (Zhelo chovtsev) comb. nov. transfdrred from Profenusa. Keys to the Chinese species of Messa, the known species of Parna, Profenusa and Ansfenusa from the world, and to the genera of the tribe Fenusini are proposed separately.
