All specimens were deposited in the Xinbin Center for Disease Control and Prevention, Liaoning province.

　　（4） Simulium (Gomphostilbia) xiangxiense sp.nov
　　The new species relates to S.(G.) tenuistylum Datta, 1973, but differs from it in sexes genitalia, pupae gill filamens stem foked branch and larvae postgenal cleft.
　　（5） Simulium (Gomphostilbia) penis sp.nov
　　The new species relates to S.(G.) jianfengense Long, An and Hao, 1994 and S.(G.) laoshanstum Ren, An and Kang, 1998, but differs from them in pupae gill filamens stem foked branch, larvae postgenal cleft and ventral dorsal view spin.
