【摘要】 本文简要介绍了生物多样性的基本概念、理论。探讨了昆虫多样性多样性研究现状和存在的问题以及我国叶蜂多样性研究现状。于2004年3～9月,2005年3～4月用路线调查法在不同的海拔和植被类型对衡山叶蜂种类和群落进行了取样调查,采用Shannon-Wiener指数、Simpson指数、Pielou指数、Whittaker指数对其叶蜂群落多样性进行了分析。 经两年的调查,在衡山采集到叶蜂共计7科36属66种(包括亚种),其中14新种:白尾暗腹三节叶蜂Arge albocaudalica Wei, sp. nov.、黑腹近脉叶蜂Phymatoceropsis melanogaster Wei et He, sp. nov.、宽环钝颊叶蜂Aglaostigma laticincta Wei et He, sp. nov.、刻胸方颜叶蜂Pachyprotasis pseudoerratica Wei, sp. nov.、双带方颜叶蜂Pachyprotasis bistriatina Wei et He, sp. nov.、黄腹宽背叶蜂Lagium xanthogaster Wei, sp. nov.、张氏斑腹叶蜂Empria zhangi Wei, sp. nov.、衡山棒角叶蜂Tenthredo hengshana Wei, sp. nov.、红盾槌腹叶蜂Tenthredo pseudocylindrica Wei et Nie, sp. nov.、三色槌缘叶蜂Pristiphora tricoloriformis Wei, sp. nov.、白鳞异片叶蜂Astethomostus tegularis Wei et Zhang, sp. nov.、中华弯瓣叶蜂Aphymatocera sinica Wei, sp. nov.、白肩纹眶叶蜂Claremontia albocollaris Wei, sp. nov.、小齿纹眶叶蜂Claremontia ungulicella Wei et He, sp. nov.。其中黑腹近脉叶蜂、宽环钝颊叶蜂、白鳞异片叶蜂己正式发表。调查研究还发现13个湖南新记录种:紫宝丽锤角叶蜂Abia formosa Takeuchii,1927、黑尾黄腹三节叶蜂Arge baishanzua Wei,1996、中华痣带叶蜂Stigmatozona sinensis Malaise,1945、黄跗方颜叶蜂Pachyprotasis xanthotarsalia Wei et Nie,2003、吴氏方颜叶蜂Pachyprotasis wui Wei et Nie,1998、尖唇方颜叶蜂Pachyprotasis acutilabria Wei,1998、黑缨麦叶蜂Dolerus guisanicollis Wei,1999、中华麦叶蜂Dolerus sinensis Wei,1997、小麦叶蜂Dolerus tritici Chu,1949、沟额斑腹叶蜂Empria sulcata Wei et Nie,1998、红头勾瓣叶蜂Macrophya erythrocephalica Wei et Nie,2003、平坦柄臀叶蜂Birka ptata Wei,1997、黄肩小片叶蜂Stethomostus flavicollaris(Sato,1928)。区系分析结果表明衡山叶蜂以东亚成分占主要优势。更多还原

【Abstract】 The concept and theory of biodiversity are introduced briefly. The current situation and problem of the research of insect biodiversity are analyzed and discussed briefly, as well as current situation of the research of sawfly biodiversity in China. The sawfly specimens were collected from different elevation and vegetation on the sample line from March to September in 2004, and from March to April in 2005 in Mt. Hengshan. The species are listed, and Shannon-Wiener index, Simpson index, Pielou index, Whittaker index are used to analyze the sawfly community diversity.Sixty six sawfly species belonging to 6 families and 36 genera have been collected from Mt. Hengshan in the research. Among them 14 new species are reported and described. They are Arge albocaudalica Wei, sp. nov., Phymatoceropsis melanogaster Wei et He, sp. nov., Aglaostigma laticincta Wei et He, sp. nov., Pachyprotasis pseudoerratica Wei, sp. nov., Pachyprotasis bistriatina Wei et He, sp. nov., Lagium xanthogaster Wei, sp. nov., Empria zhangi Wei, sp. nov., Tenthredo hengshana Wei, sp. nov., Tenthredo pseudocylindrica Wei et Nie, sp. nov., Pristiphora tricoloriformis Wei, sp. nov., Astethomostus tegularis Wei et Zhang, sp. nov., Aphymatocera sinica Wei, sp. nov., Claremontia albocollaris Wei, sp. nov., Claremontia ungulicella Wei et He, sp. nov.Also, 13 species are firstly recorded in Hunan Province: Abiaformosa Takeuchii, 1927, Arge baishanzua Wei, 1996, Stigmatozona sinensis Malaise, 1945, Pachyprotasis xanthotarsalia Wei et Nie, 2003, Pachyprotasis wui Wei et Nie, 1998, Pachyprotasis acutilabria Wei, 1998, Dolerus guisanicollis Wei, 1999, Dolerus sinensis Wei, 1997, Dolerus tritici Chu, 1949, Empria sulcata Wei et Nie, 1998, Macrophya erythrocephalica Wei et Nie, 2003, Birka plata Wei, 1997 and Stethomostus flavicollaris (Sato, 1928). Fauna analysis showes that the east Asian species are superior.The dominant species of sawfly on Mountain Hengshan is very obvious. And the phenomenon is distinct in April and May. In April Phymatoceropsis melanogaster is the senior dominant species, Taxonus annulicornis Takeuchi is the junior dominant更多还原
