Current Knowledge of Mesozoic Coleoptera from Daohugou and Liaoning(Northeast China)

The present paper is devoted to an overview on fossil Coleoptera studied from Inner Mongolia, Daohugou （Middle Jurassic, Jiulongshan Formation） and Liaoning （Upper Jurassic-Lower Cretaceous, Yixian Formation） deposited in Chinese collections. As a result, species of the tribe Sperchopsini and Hydrophilini from Hydrophilidae, families and subfamilies Silphidae, Syndesinae from Lucanidae, Pleocomidae, Trogidae, Trogissitidae, Pyrochroidae, Diaperinae from Tenebrionidae, and Cerambycidae were first registered in the Mesozoic and some families were defined as new. It was shown that many superfamilies represented in the Recent Fauna were formed within the Middle Jurassic and Lower Cretaceous. The materials examined confirm the hypothesis that Cucujiformian beetles are a younger group than other infraordera of Polyphaga （Staphyliniformia and Elateriformia） and, therefore, they appeared in the fossil record only in the late Mesozoic. It was shown and confirmed that most superfamilies appeared in the fossil records before Cucujoidea. The synonymy of Notocupes Ponomarenko, 1964; Sinocupes Lin, 1976, syn. nov.; Amblomma Tan, Ren et Liu 2005, syn. nov.; Euryomma Tan, Ren et Shih, 2006, syn. nov., non Stein, 1899 and Ovatocupes Tan et Ren, 2006, syn. nov.; synonymy of Tetraphalerus Waterhouse, 1901 and Odontomma Tan, Ren et Ge 2006, syn. nov.; and synonymy of Priacmopsis Ponomarenko, 1966 and Latocupes Tan et Ren, 2006, syn. nov. are proposed. Sinorhombocoleus papposus Tan et Ren, 2009 is transferred from the family Rhombocoleidae to Schizophoridae. Cervicatinius complanus Tan, Ren et Shih, 2007 and Forticatinius elegans Tan, Ren et Shih, 2007 are transferred from the family Catiniidae （suborder Archostemata） to superfamily Cleroidea （suborder Polyphaga： first among the family Peltidae and second as a closely related group to the latter family）. The family Parandrexidae is transferred from the superfamily Cucujoidea to Cleroidea. The ecological circumstances of the past ecosystems and hypotheses of historical development of the order Coleoptera are discussed. The age of faunas examined is considered. The list of the taxa described from Daohugou and Liaonlng is compiled.

Review of the Permian Camptoneuritidae(Insecta:Grylloblattida)

The Permian family Camptoneuritidae （Insecta： Grylloblattida） is reviewed. New synonymies are proposed： Camptoneuritidae Martynov, 1930 = Demopteridae Carpenter, 1950, syn. nov., = Jabloniidae Kukalova, 1964, syn. nov. Key to genera of Camptoneuritidae is given. All genera are redescribed and illustrated. Camptoneurites soyanensis sp. nov. from Soyana locality （Middle Permian, Kazanian Stage; Arkhangelsk Region, Russia） and Tyulkinia bashkuevi gen. et sp. nov. from Tyulkino locality （Lower Permian, Kungurian Stage; Perm Region, Russia） are described.
