The first Chinese fossil of the family Nymphidae (Neuroptera: Myrmeleontiformia) is briefly described and figured along with two episomyline Osmylidae, a generally plesiomorphic group which can be easily confused with nymphids when only wings are known. Four new species and three new genera are characterized from Jurassic deposits of the Jiulongshan Formation (Daohugou Biota), Inner Mongolia, China. New genera are Liminympha (Nymphidae), Eiwdinympha (Osmylidae), andNilionympha (Osmylidae), while the new species are Liminympha makarkini, Enodinympha translucida, Nilionympha pulchella, and N. imperfecta.
