42 trees are obtained and the 13th is most acceptable. the results show that the evolutionary inclination of forewing and hindwing of empoascini is that the forewing evolved from these whose veins of mp " are derived from cell r, to these whose mp " from cell m, and the most advanced taxa include these whose 3 distal veins are derived from cell m. the hindwing are evolved from these whose cua is branched and the mp " + cua " is presented, to those whose cua is unbranched and mp " + cua " disappeared, based on the above analysis, the genera of empoascini can be divided into two groups : one group includes these whose mp " + cua " are present, the other consists of those whose mp " + cua " are disappeared
在系統發育方面，應用hennig86 （ version1 . 5 ）軟體，根據中國小綠葉蟬族40個屬及外群dikraneura ，首次研究了該族的系統發育關系，根據研究結果初步提出了該族前、后翅脈的進化方向，即該族前翅翅脈呈現出mp脈源於r室，逐漸進化到mp脈源於m室，最後前翅3條端脈皆源於m室的趨勢；后翅翅脈由cua脈端部分二叉，進化到后翅cua脈端部不分叉、 mp + cua脈退化的趨勢。
