Some Jurassic Palaeontinidae (Insecta, Hemiptera) from Daohugou, Inner Mongolia, China

Five species, belonging to three known genera of the family Palaeontinidae (Insecta, Hemiptera), are described from Daohugou in Inner Mongolia, China. They are Fletcheriana colorata n. sp., F. minuta n. sp., Palaeontinodes cf. shabarovi Martynov, 1937, P. cf. angarensis Becker-Migdisova and Wootton, 1965 and Plachutella magica n. sp. Veins ScA and A2 were clearly recognised from P. cf. shabarovi and P. cf. angarensis. The evolutionary trend of this family and some wing structural characteristics are discussed. The discovery of these palaeontinids indicates that the Daohugou strata are probably Early-Middle Jurassic in age.
