中国斑叶蝉族分类研究

The Erythroneurini is larger tribe of subfamilay Typhlocybinae and the kinds are extremely abundant. At present, the taxonomics of Erythroneurini has been paid much more attention with new taxa erected constantly in recent years. However, the systematic classification of this group has not been surveyed in China yet, family property is unclear, so, it need to be further studied as soon as possible.The present project will collect furthest adult specimens, classify the materials by genera, erect new taxa and increase the Chinese known species and higer taxa. Some error identified genera, species and synonym will be amended and the keys for genera and species will be made by comparing characteristics of adult morphology and genitalia. The China's leafhopper component characteristics of insect fauna will be analysed; using the cladistics principle and method, selecting the main morphological characteristics of adult and some other parts of biology and ecology of important features which are closely related to system development to analyse the intergeneric phylogenetic relationships, establish the identification and retrieval system. Basing on well prepared research, the project will be a new exploration to deepen the study of this group leafhoppers with innovation in taxonomic theory and methodology. The prospective achievements are considerably significant in understanding the known species richness of the fauna and promoting the developedment of entomology in China.

斑叶蝉族是小叶蝉亚科中较大的族，种类丰富。目前，国际斑叶蝉研究十分活跃，新的分类单元不断被发现，然而我国尚未对该类群进行系统而全面的分类调查，家底不清，是我国亟待深入研究的昆虫类群。该研究将充分利用我国丰富的物种资源，查清该族种类组成；规范部分属、种鉴别特征，考订部分误鉴属、种，建立新的分类单元及部分新组合，大幅提高我国斑叶蝉物种及高级阶元总量。分析我国斑叶蝉族昆虫区系成分特征；应用支序分类学的原理和方法，挑选成虫主要形态结构特征，辅助部分生物学和生态学等与系统发育密切相关的重要特征，分析探讨属间系统发育关系，建立我国斑叶蝉可靠的鉴定与检索体系。 项目具有扎实的前期研究基础，是利用分类理论深化我国叶蝉研究的全新探索，具有丰富中国及世界动物区系，促进昆虫分类学理论和推进我国昆虫学发展的重要意义。

斑叶蝉族是小叶蝉亚科中较大的族，种类丰富。目前，国际斑叶蝉研究十分活跃，新的分类单元不断被发现，然而我国尚未对该类群进行系统而全面的分类调查，家底不清，是我国亟待深入研究的昆虫类群。.该研究充分利用我国丰富的物种资源，查清该族种类组成；规范部分属、种鉴别特征，考订部分误鉴属、种，建立新的分类单元及部分新组合，大幅提高了我国斑叶蝉物种及高级阶元总量。共记述中国斑叶蝉族44属254种。分析了我国斑叶蝉族昆虫区系成分特征；中国斑叶蝉44属在世界动物地理区划中有8种区系型，在中国动物地理区划中的归属共有21种区系型。我国斑叶蝉在种级水平上，以华中区种类最为丰富，华南区次之，西南区仅次于华南区而居于第三位。应用支序分类学的原理和方法，挑选成虫主要形态结构特征，辅助部分生物学和生态学等与系统发育密切相关的重要特征，分析探讨了属间系统发育关系。.应用PAUP*4.0软件采用MP、NJ 两种建树方法，选取72个性状特征和2个外群，对其进行系统发育分析研究，获得最简约支序图和最小进化树。.该项目具有扎实的前期研究基础，是利用分类理论深化我国叶蝉研究的全新探索，在一定程度上丰富了我国及世界动物区系，在促进昆虫分类学理论和推进我国昆虫学发展等方面具有重要科学意义。
