摘　　要：记述分布于中国四川西部有瓣蝇类中的3新种:大喙鬃粪蝇(Norelliamegistomyctasp.nov.)(粪蝇科);峨眉池蝇(Limnophoraemeishanicasp.nov.)及山顶池蝇(Limnophoraoreosoacrasp.nov.)(蝇科)。模式标本存于中国科学院上海生命科学研究院植物生理生态研究所。Three new species, Norellia megistomycta sp.nov., Limnophora emeishanica sp.nov.and L.oreosoacra sp.nov., belonging to Scathophagidae and Muscidae are described in the present paper. The type specimens are kept in the Institute of Plant Physiology & Ecology, Shanghai Institute for Biological Sciences, Chinese Academy of Sciences, Shanghai, China.1 Norellia megistomycta Feng, sp. nov.(Fig.1) Male: Body length 7.0 mm, wings length 7.0 mm. This new species belongs to Norellia Robineau-Desvoidy, 1830 of Scathophaginae. It is similar to N.triangula Sun, 1992, but can be distinguished from the latter by the following characters: Femora with black streak on dorsal surface with clear limits; arista pubescent; inner margin of lateral lobe of 5th sternite with 2-3 rows of small and short spines on whole length; thorax without pollen. Female: Unknown. Holotype ♂, Mt.Erlangshan (Yakou, 3000 m; 29°52′N, 102°10′E), Sichuan Province, China. 1984-07-02, collected by Feng Yan.2 Limnophora emeishanica Feng, sp.nov.(Fig.2) Male: Body length 5.0 mm. This new species belongs to Limnophorini of Coenosiinae. It is similar to L.fallax Stein, 1920, but can be distinguished from the latter by the following characters: Postintraalar bristle 1; mid tibia with p 2; basal part of scutellum without a cross black band; both of lateral margins of 5th sternite inward concaved; distal part of surstyli of male backward obliquely in lateral view. Female: Unknown. Holotype ♂, Mt.Emeishan(Wanfoding, 3099 m; 29°59′N, 103°42′E), Sichuan Province, China. 1984-06-22, collected by Feng Yan.3 Limnophora oreosoacra Feng, sp.nov.(Fig.3) Male: Body length 5.0 mm. This new species belongs to Limnophorini of Coenosiinae. It is similar to L.nigra Xue, 1984, but can be distinguished from the latter by the following characters: Fifth tergite without black spot; distal part of fore tibia with a pv seta largely; distal part of surstyli of male backward carved in lateral view; distal part of cerci of male sharpened in lateral view. Female: Unknown. Hol
