Zoogeographical analysis shows that most chinese genera and species were found in oriental region , especially in southern yunnan subregion ( viib ) of south china region ( vii ) then in southwest mountain subregion ( v a ) of south - west china region ( v ) 中国现有的39属259种主要分布于东洋区中印亚界华南区，尤以滇南山地亚区分布的种类最多，西南区的西南山地亚区次之。

The distribution of all the genera and species ( including new taxa and new data by present research ) of the world are summarized , according to the history of continental drift and the result shows that empoascini originated in the oriental region in pangaea 145maago . zoogeographical analysis of all the taxa in china shows that most of the genera and species of empoascini are distributed in the oriental region , which is identical with the geographical distribution worldwide , i . e . most taxa distribute in the tropical and subtropical zone . phylogenetic analysis of 40 chinese genera of empoascini with one outgroupikranewa is presented in this paper 在生物地理及区系方面，总结了世界已报道及本研究新发现单元共计88属1183种在世界各大动物地理区的分布情况，结合大陆漂移学说的有关知识，认为小绿叶蝉族应起源于东洋区，起源时间在联合古陆时期(约145ma以前) ；分析了中国已报道及本文新发现该族共40属263种在中国动物地理区划的归属，结果表明，中国小绿叶蝉族的种类分布以东洋区占优势，明显多于古北区，这与世界该族昆虫大多分布于热带、亚热带的结果相一致。
