Two new species of Jurassic Chrysopidae are described: Mesypochrysa sinica sp. nov. (Limaiinae) from the Middle–Upper Jurassic boundary interval of Daohugou (China) and Baisochrysa pumila sp. nov. (Limaiinae) from the Upper Jurassic of Karatau (Kazakhstan). Mesypochrysa intermedia Panfilov, 1980, previously known from Karatau, is recorded from Daohugou. Mesypochrysa sinica sp. nov. and M. cf. intermedia from Daohugou are considered to be the earliest known, unquestionable green lacewings. Lembochrysa Ren and Guo, 1996 is synonymized with Mesypochrysa Martynov, 1927. Mesypochrysa makarkini Nel et al., 2005 is synonymized with M. intermedia, and the size range of their forewings is discussed. Male and female terminalia of the Mesozoic green lacewings are described for the first time. The diversification of ants is considered a possible cause of the extinction of Limaiinae during the early Eocene.
