Abstract


From May 2008 to July 2009, the author collected about 4903 sawfly specimens in Shennongjia National Nature Reserve. The author also searched the sawfly specimens that are deposited in the Insect Collection of Central South University of Forestry and Technology (CSCS). Totally 256 sawfly species and 18 genera belonging to the subfamily Tenthredininae of Tenthredinidae are recorded from Mt. Shennongjia in Hubei during the research period. Among them,100 species are undescribed new species,1 genera and 1 species is recorded for the first time in China and 71 species are firstly recorded in Hubei Province.Following 9 new species, Tenthredo latidentella Wei et Zhao, sp. nov., Macrophya pseudohistrio Wei, sp. nov., Macrophya shennongjiana Wei et Li, sp. nov., Macrophya jiangi Wei et Li, sp. nov., Macrophya liui Wei et Niu, sp. nov., Macrophya zhaofui Wei et Li, sp. nov., Macrophya pseudoimitator Wei et Niu, sp. nov., Macrophya longipetiolata Wei, sp. nov. and Macrophya pseudoannulitibia Wei et Niu, sp. nov., are described and illustrated. Type specimens of the new species are deposited in the Insect Collection of Central South University of Forestry and Technology.According to Eastern Asia fauna compartmentalization measure, fauna analyses of Shennongjia shows that Eastern Asia fauna elements are the principal part, accounting for 98.83 percent of total species. Three species (1.17 percent of all) belong to Palaearctic elements. The result shows that in Shennongjia the East Asia elements are relatively predominant. The main fauna components of Shennongjia are East Asian species and the East Asian fauna property is very significant. In East Asian fauna, there are 73 species distributing in the eastern margin of the second terrain,52 species in southern part of China,49 species in "T-area",40 species in Mt. Shennongjia and 39 species in east of Asian. They accounted for 28.52%,20.31%, 19.14%,15.63% and 15.23% separatedly.The Tenthredininae fauna from Mt. Dabie, Mt. Mufu, Mt. Mang, Mt. Fanjing and Mt. Qinling are compared with the Tenthredininae fauna from Mt. Shennongjia based on multivariate similarity analysis of fauna. These six areas total have 669 species,93 endemic species,246 mutual species. The similarity coefficient of six areas is 0.3902. Contribution rate of Mt. Shennongjia and Mt. Qinling is higher than other 4 areas. The difference coefficient of six areas is 0.6098. Contribution rate of Mt. Shennongjia and Mt. Qinling is slightly higher than other 4 areas, but contribution rate of these areas don’t have great difference.According to the similarity indices put forward by Jaccard, we can get the conclusion that the order of similarity indices of Tenthredininae. The similarity index between Mt. Shennongjia and Mt. Qinling is much higher than other 4 areas.
