【Abstract】 Mt. Mao’er Nature Reserve, situated in the northeast of Guangxi Zhuang Autonomous Region, is among the important compositions of Nanling Range. The sawfly species were collected from different elevation and vegetation along the sampling line from March to August in 2006 on Mt. Mao’er. The species are listed, and Shannon-Wiener index, Simpson index, Pielou index, Whittaker index are used to analyze the sawfly community diversity.One hundred and fifty eight sawfly species belonging to 17 families and 67 genera are collected from Mt. Mao’er during the research period. Among them,33 new species are reported. They are Arge nigropilosis Wei, sp. nov., Arge curvatitheca Wei, sp. nov., Arge dolichopoda Wei, sp. nov., Arge liaoae Wei, sp. nov., Leptocimbex longivertexila Wei, sp. nov., Corrugia liaoae Wei, sp. nov., Nesoselandria southa Wei, sp. nov., Nesoselandria albotegularina Wei, sp. nov., Nesoselandria brevissima Wei, sp. nov., Neostromboceros yangqingi Wei, sp. nov., Neostromboceros latimaculatus Wei, sp. nov., Neostromboceros xiaoweii Wei, sp. nov., Neostromboceros guangxiensis Wei, sp. nov., Hemitaxonus maculoscutus Wei, sp. nov., Caliroa liaoae Wei, sp. nov., Pristiphora liaoae Wei, sp. nov., Priophorus xiaoi Wei, sp. nov., Pristiphora xiaoi Wei, sp. nov., Empria zhangae Wei, sp. nov., Mallachiella xiaoi Wei, sp. nov., Pseudolinomorpha yangi Wei, sp. nov., Darjilingia acutitheca Wei, sp. nov., Corymbas sinica Wei, sp. nov., Siobla youae Wei, sp. nov., Pachyprotasis lianyuanensis Wei et Zhong, sp. nov., Pachyprotasis elevifrontalis Wei et Zhong, sp. nov., Tenthredo lineistriata Wei, sp. nov., Tenthredo nitidifrontalia Wei, sp. nov., Hemibeleses bistriatus Wei, sp. nov., Abeleses circulitibialis Wei et Niu, sp. nov., Amonophadnus megadentus Wei, sp. nov., Nesotomostethus nigrotegularis Wei, sp. nov., Periclista liaoae Wei, sp. nov.5 new record species from China are reported, they are Athlophorus gracilis orbitalis (Konow,1848), Tenthredo laevssima (Malaise, 1945), Tenthredo appendicella(Malaise,1945), Tenthredopsis birmanica (Malaise, 1945), Claremontia sinobirmana (Malaise,1964). Nine new species and one new record species from China were reported in this thesis.The diversity indices of sawfly communities in this region are ranked as following:April> May> July> March> June> August; the order of dominance indicies are as following:August>July> June> March> May>April; the sequence of evenness indices are March>April>August>May>July>June.The diversity indices of sawfly communities from different elevation of the mountain are (1100-1400)m> (1400-1700)m>(300-500)m>(500-800)m>(800-1100)m> (1700-2000)m> (>2000)m; the order of dominance indices are (1700-2000)m> (>2000)m>(300-500)m>(500-800)m>(800-1100)m>(1100-1400)m>(1400-1700)m; the sequence of evenness indices are (1400-1700)m> (800-1100)m> (1100-1400)m> (500-800)m>(300-500)m>(>2000)m>(1700-2000)m.According to the data obtained from investigating in different vegitation, the diversity index of sawfly communities from the highest to the lowest is:evergreen broadleaved forest, Moso bamboo forest, deciduous broad-leaves forest, shrub forest coppice at mountaintop; the dominance index of different vegetation is:shrub forest at mountaintop, Moso bamboo forest, evergreen broadleaved forest, deciduous broad-leaves forest; the evenness index of different vegetation is as following: evergreen broadleaved forest, Moso bamboo forest, deciduous broad-leaves forest shrub forest at mountaintop.The Whittaker indices show that the change rate of sawfly species in time grrade is highest, while it is lowest in vegetation gradient.Among the 158 species described,150 East Asia-type species, accounting for 94.94% of all,6 Oriental species, about 3.80% of all,1 Oriental-East Asia-type specie, about 0.63% of all, and 1 Oriental-Palaeartic specie, about 0.63% of all. The result shows that in Mt. Mao’er the East Asia-type element is relatively predominant.更多还原
