The research on Ephemeridae in China was limited. Only one genus and 21 species have previously been reported in China by Eaton (1870￣1871,1892),Mclachlan (1904), Ulmer (1912,1920,1924,1936),Navas(1930,1934￣1936),Hsu Yinchi(1931￣1932,1935￣1938) and Tshernova(1973).In recent years,we collected specimen Ephemeridae,and studied them. As a result,we intend, in this paper, to describe eight new species of Ephemera Linnaeus (1758).These species are E.maoyangensis sp.nov.,E.jianfengensis sp. nov.,E.wanquanensis sp. nov., E. hainanensis sp.nov.,E.hongjiangensis sp. nov.,E.hsui sp. nov.,E.zhangjiajieensis sp. nov. and E.hunanensis sp. nov. One genus Eatonigenia Ulmer and two species, Eatonigenia chaperi(Navas)and Ephemera sachalinensis Matsumura are new records in China. So far two genera and 31 species have been found in China. The number of genus Ephemera species found in China is the highest around the world.
