小绿叶蝉族隶属于半翅目、叶蝉科、小叶蝉亚科，在世界各地均有分布。本项目主要研究中国小绿叶蝉族昆虫种类组成、区系、分子特征及系统发育。项目将最大限度地收集标本，进行分类鉴定，以查清中国小绿叶蝉族的种类组成，分析中国小绿叶蝉族的区系组成、特征及区系演化规律；主要获取中国小绿叶蝉族昆虫的28S rDNA、16S rDNA、COI和COII基因序列信息，构建该族昆虫分子特征数据库；应用支序分类学原理和方法，基于形态和分子数据，采用PAUP*4.0或Mega4分析软件，分析中国小绿叶蝉族属种间系统发育关系，提出合理的分类建议。研究结果将深化对中国小绿叶蝉族昆虫物种多样性的认识，丰富该类群分子特征数据，为中国动物地理学和系统动物学研究提供科学资料。

The leafhopper tribe Empoascini belongs to Typhlocybinae of Cicadellidae of Hemiptera, which is distributed worldwide. This project mainly studies the fauna, molecular features and phylogeny of the tribe Empoascini of China. The missions of the project are listed as follows: furthest collecting specimens of the Chinese Empoascini, then classifying and identifying so as to make a thorough investigation of species diversity of the Chinese Empoascini, and analyzing faunal elements, characteristics and faunal evolvement pattern of the Chinese Empoascini; mainly obtaining 28S rDNA, 16S rDNA, CO Ⅰ and CO II gene sequences data and build molecular data base of the Chinese Empoascini species; based on morphological and molecular data, applying methods and principles of Cladistics to study the phylogeny and evolutionary history of the Empoascini by using analysis software (PAUP*4.0 or Mega4), and putting forward reasonable taxonomic advice, to collate and stipulate senior taxonomic system. The results will deeply cognize the species diversity of Empoascini leafhoppers, enriching molecular features data of this group, also providing the scientific data for Chinese Zoogeography and Systozoology.
