A Systematic Study Of Macrophya From China (Hymenoptera, Tenthredininae)

The research histories of the genus Macrophya Dahlbom are briefly reviewed. The morphology, taxonomic and biological characters of the genus are outlined. Based on the analysis of the generic and specific distribution of Macrophya Dahlbom the distribution pattern and the possible origination of the genus is discussed. It is seemed that east-southern region of Mt. Himalayas and Mt. Hengduan with neighbouring area is probably the derivation center of Macrophya. The taxonomy of Macrophya from China is also studied in detail in the thesis. Key to known species of the genus from China are given. Totally 110 species from China are described. Among them 41 species are new to science and 2 species are new records in China. To each species full incitations, morphological description, diagnostic characters, distribution, specimens examined are provided, as well as female and male genitalia illustrations of almost all species. Type specimens are deposited in the bisect Collection of Institute of Insect Resources of Central South Forestry University, Zhuzhou, China. The new species and new recorded species from China are as folio wings:New species:M. jilinensis Chen et Wei, sp. nov.M. zhui Chen et Wei, sp. nov.M. tibetana Chen et Wei, sp. nov.M. leucotarsalina Chen et Wei, sp. nov.M. breviclypea Chen et Wei, sp. nov.M. shennongjiana Chen et Wei, sp. nov.M. acuminiclypea Chen et Wei, sp. nov.M. megasculpturalis Chen et Wei, sp. nov.M. parviserrula Chen et Wei, sp. nov.M. flavomaculata jinggangensis Chen et Wei, sp. nov.M. xanthosoma Chen et Wei, sp. nov.M. histrio nigrihistrio Chen et Wei, sp. nov.M. frontalis Chen et Wei, sp. nov.M. allominutifossa Chen et Wei, sp. nov.M. trimicralba Chen et Wei, sp. nov.M. paracoxalis Chen et Wei, sp. nov.M. bui Chen et Wei, sp. nM. jiuzhaina Chen et Wei, sp. nov.M. fulvostigmata Chen et Wei, sp. nov.M. zhongi Chen et Wei, sp. nov.M. minutiluna Chen et Wei, sp. nov.M. pentanalia Chen et Wei, sp. nov. %M.jiangi Chen et Wei, sp. nov.M. opacifrontalis Chen et Wei, sp. nov.M. changbaina Chen et Wei, Sp. nov.M. rent Chen et Wei, sp. nov.M.
