摘　　要：Two new genera and species of fossil Palaeontinidae are described from Daohugou Village, Inner Mongolia, China： Cladocossus undulatus gen. et sp. nov. and Cricocossus paradoxus gen. et sp. nov. Both new genera are described based on well-preserved forewings. This discovery confirms the high diversity of palaeontinids during the Middle Jurassic. Both specimens have interesting modal structures which are new to Palaeontinidae： M five-branched and M3 with two branches. Based on this character, wing structural characteristic is discussed.Two new genera and species of fossil Palaeontinidae are described from Daohugou Village, Inner Mongolia, China： Cladocossus undulatus gen. et sp. nov. and Cricocossus paradoxus gen. et sp. nov.
