中文摘要： 泰莱蛛科蜘蛛隶属于简单生殖器类蜘蛛，目前已知种多为洞穴分布。该科物种数目不多，但分布广泛，除南美洲和澳洲外在各大洲都有报道，其中以我国西南及周边地区报道物种数目最多，占该科蜘蛛一半以上，另外还有大量新种有待描述。本项目拟以世界泰莱蛛科蜘蛛为研究对象在利用DNA分类和形态学结合完成物种鉴定的基础上，开展基于基因证据的分子系统学研究，理清泰莱蛛科蜘蛛的系统发育关系，并探讨该科蜘蛛的历史演化进程，揭示其现今世界分布格局，特别是我国西南地区及周边地区生物多样性丰富的成因。

英文摘要： The family Telemidae belongs to the Haplogynae spiders, and most of species are founded in caves. The number of species of the family is small, but they are wildly distributed in Europe, North American, African and Asia. The family has a high biodiversity and species differentiation in Southweat China and the surrounding area, more than half of the species of the family had been reported here, and there are still a lot of new species need to be described. In this project, we will carry out a systermatic taxonomy research on Telemidae worldwidely based on morphology and DNA barcoding research, and then amplify six gene sequences including three mitochondrial and three nuclear. In order to investigate the phylogenetic and phylogeographic structure of the Telemidae molecular phylogenetic studies will be conducted based on the sequences The results will not only enhance our understanding of the origin, evolution, phylogeography and phylogenetic relationships of world Telemidae, but also shed lights on the rich biodiversity in Southwest China and the surrounding area.
