中文摘要: 本项目在中国横脊叶蝉分类研究基础上,综合应用比较形态学、支序系统学、分子生物学、动物地理学等方法,对世界范围横脊叶蝉亚科昆虫进行了区系、分类、系统发育和生物地理学研究;在对已知类群进行修订的同时,记述发表1新记录属、11新种,提出5新组合,明晰了世界横脊叶蝉的物种多样性水平及其区系;重建了横脊叶蝉亚科的系统发育关系,明确了该亚科各属及其与近缘亚科间的亲缘关系;在分类、系统修订、系统发育研究基础上,对该亚科的生物地理学进行了研究,分析探讨了该亚科的起源、扩散和现有分布格局的特点。本项目的研究结果在进一步丰富世界横脊叶蝉区系、廓清该亚科各属级单元及相关近缘亚科的系统关系的同时,为进一步探讨叶蝉科的系统发育研究奠定了基础,并使我国在该类群的研究处于世界前沿水平。

英文摘要: This project,based on our finished research on the taxonomy of the Evacanthinae from China, aimed to clarify the Evacanthinae fauna worldwide and construct the phylogeny of this subfamily by using methods of comparative morphology, cladistics, molecular biology,and biogeography,etc. The primary results of the project are as follows: (1) Known evacanthine taxa are revised with 11 new species described and one new recorded genus to China reported, 5 new combinations proposed. (2) The evacanthine fauna worldwide and its biodiversity are clarified. (3) The phylogeny of the Evacanthinae and other related leafhopper subfamilies is construced, and relationships among different taxa of the subfamily and other related groups are discussed. (4) The biogeography of the Evacanthinae is expatiated, including its origin, dispersal and current distribution partterns, etc. The results mentioned above enrich the fauna of the world leafhoppers and set a solid base for the future research and for understanding the phylogeny of the family Cicadellidae.
