英文
wing media-
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。Most notable fossils from this area are from the terrestrial jurassic especially in jiulongshang formation of middle jurassic and yixian formation of late jurassic, where abundant insect fossils such as snakeflies and lacewings and other insects have been discovered, providing important evidence for the study of the origin and early evolution of insects
該區大部分著名的陸生化石主要采自於中侏羅世的九龍山組和晚侏羅世的義縣組地層中。在這些化石中，昆蟲化石（如蛇蛉目和脈翅目）極為豐富，為研究昆蟲的起源和早期演化提供了重要的證據。According to the paleobiogeographic analysis, the region underwent four evolutionary episodes during late mesozoic. in part five, a comprehensive taxonomic work on jurassic raphidioptera and neuroptera is presented. 7 new genera and 10 new species within raphidioptera and 42 new genera and 56 new species within 13 neuropteran families are reported and illustrated by 92 line drawings and 100 photos from this area. 2 new families and 1 new subfamilies are newly proposed
第五部分：對遼寧省西部和內蒙古自治區東部的蛇蛉目和脈翅目化石進行了較全面的研究，報道蛇蛉目3科12屬16種，其中7新屬10新種；脈翅目13科43屬56種，其中2新科， 1新亞科， 42新屬56新種。Both raphidioptera and neuroptera are small orders, with a little more than 5000 described species all over the world
蛇蛉目和脈翅目均是昆蟲綱中的小目，全世界已知種數不超過5000種。分享友人
