The taxonomy of the Chinese Schoenobiinae is revised. In total, 12 genera and 49 species are recognized. This paper presents keys to the genera and species, illustrations of wing venation for each genus, and line drawings of genitalia of most species. Two new species, namely, Schoenobius scirpus sp.nov, and Ramila minima sp.nov., are described. The female of Scirpophaga adunctella Chen, Song, and Wu, 2006 is reported for the first time. Donacaula forficellus （Thunberg, 1794） reported by Wang （1980） is proven to be a misidentification orS. scirpus sp.nov. The diagnostic characteristics of Schoenobiinae and the taxonomic status of some genera are discussed. Acropentias, Leechia, Brihaspa, and Promacrochilo are suggested to be removed from the subfamily because these genera do not share any synapomorphic characters with Schoenobiinae.
Three species of the genus Eugauria Snellen are reported, in which two species are described as new to science, named E. arcuosa Chen ＆ Wu, sp. nov. and E. crenata Chen ＆ Wu, sp. nov. The adults and genitalia structures of all species are described and illustrated. A key to the species of the genus is provided.
