Four new fossil genera and species of true bugs from the family Pachymeridiidae, Beipiaocoris multifurcus,Bellicoris mirabilis,Nitoculus regillus,and Viriosinervis stolidus,are described.New specimens were collected from the Middle and Upper Jurassic non-marine sedimentary strata from the Jiulongshan and Yixian Formations of northeast China.The species Karatavocoris asiatica Becker-Migdisova,1963,which was considered to be a member of the family Coreidae is transferred to the Pachymeridiidae.A new map of all known and newly discovered fossil pachymeridiid localities is given.The diagnosis of the family is modified.
