摘　　要：通过对中国已记载的小异长足虻属昆虫162种进行区系分析研究,结果发现:中国小异长足虻属昆虫在世界动物地理区划中有5种分布型,以东洋界为主,其次为古北界;在中国动物地理区划中有14种分布型,以华中区为主;中国小异长足虻属昆虫广布种少,特有种多;跨界分布的种类较少,跨中国动物地理区分布的种类也较少,说明了中国小异长足虻属昆虫分布地狭窄,不善于扩散。This papper analyzed the faunal structure of 162 species of Chrysotus（ Diptera,Dolichopodidae） known from China. The results showed that the insects of Chrysotus constituted 5 types of distribution in Zoogeographic regions in the world. It is clear that Oriental species made up the majority of Chrysotus from China,and the number of Palaearctic in the secend place. And constituted 14 types of distribution in seven hinese Zoogeographic regions,and they distributed mainly in Central China subregion. It was few that the number of cosmopolitan species of Chinese Chrysotus,but most of them are endemic species. Few of them are straddle faunal type species,and the species number of straddle the China sub-region are little,which is revealed that the distribution area of Chrysotus is narrow and the insects are not good at diffusion.
