舞虻族是双翅目舞虻科中最大的族,隶属于舞虻亚科,已知1400余种，广泛分布世界各地；其成虫和幼虫均为捕食性,为一些重要农林及卫生害虫的天敌。目前我国舞虻族仅已知49种，尚缺乏系统分类工作。.本项目拟对我国舞虻族的分类进行全面系统的研究,完成对各属分类的系统修订，查清我国的种类，建立我国舞虻族的分类鉴定体系；此外，还开展比较形态学研究，运用支序系统学方法对舞虻族的系统发育进行探讨，检验各属和族的单系性，重建属之间的系统发育关系，并根据系统发育研究的结果，修订和完善族的分类系统。研究结果将为舞虻科昆虫多样性保护提供基础资料，对于开展我国该类天敌昆虫多样性的保护及其在害虫生物防治上利用研究具有重要的意义。

Empidini is the largest tribe in the family Empididae(Diptera)and belongs to the subfamily Empidinae. It contains over 1400 known species distributed worldwide. Their adults and larvae are significant predators of some important crop, forest and health pests. But now the tribe Empidini in China is poorly studied with only 49 known species. .The present project is to make a study of systematics and phylogeny of Empidini from China. The species of each genus of Empidini will be revised in order to clarify.the fauna of China.The phylogenetic relationships among genera of Empidini are studied by the cladistic analysis. The monophyly of genera and tribe and phylogenetic relationships among genera of the tribe will be clarified. Based on the result of the phylogenetic study, the general classification of the tribe will be modified. This project will provide new data for the biodiversity of Empididae and play an important role in the biodiversity conservation and sustainable exploitation of dance flies.
