Abstract: Objective To investigate the species and geographic distribution, community composition of Ceratopogonidae in Dayaoshan National Nature Reserve of Guangxi Zhuang Autonomous Region, China. Methods The investigation of Ceratopogonidae was conducted in Dayaoshan National Nature Reserve of Guangxi Zhuang Autonomous Region from July 18-22, 2015. The light (photocatalyic UV trap lamp) trap and insect net were used to capture midges, which were classified and identified. Results There are 6 genera, 18 species biting midges from Dayaoshan National Nature Reserve, including 2 genera and 10 species in the subfamily Ceratopogoninae, 1 genera and 2 species in Dasyheleinae, and 3 genus and 6 species in Forcipomyiinae. We have found 11 new record species in Guangxi, including Dasyhelea jingboi,Forcipomyia distapalpis, Atrichopogon okinawensis, A. dehiscentis, A. jianfengensis, Culicoides orientalis, C. indianus, C. innoxius, C. lansangensis, C. pictimargo, and Stilobezzia alba. Conclusion This paper enriches the species diversity of Ceratopogonidae and provides basic data for the prevention and control of midge-borne viral diseases and blood sucking midges.
