| Eastern Inner Mongolia and Western Liaoning are located in the Northeast part of China. This area is one of the most typical in the world,with well-developed continental Mesozoic sediments,yielding abundant fossils.Most motable fossils from this area are from the terrestrial Jurassic,especially in Jiulongshan Formation of Middle Jurassic and Yixian Formation of Late Jurassic,where abundant insect fossils have been discovered,providing important evident for the study of the origin and early evolution of insects.The present paper is a taxonomic study of fossil Pelecinidae from Northeast China.Firstly, the researching history on Hymenoptera is provided.Secondly,the morphology and biology are reviewed.Then the origin,evolution and phylogenesis of Hymenoptera are discussed.11 species of 8 genera within Pelecinidae are reported,of which 3 species and 2 genera have been published, 7 species of 4 genera are new to science,and lspecies and genus are reviewed.The new genera and new species in this paper are listed as follows:New genera:Archaeopelecinus Shih,Liu and Ren,2009;Cathaypelecinus Shih,Liu and Ren,2009;Megapelecinus gen.nov.;Abropelecinus gen.nov.;Azygopelecinus gen.nov.; Shoushida gen.nov.New species:Archaeopelecinus tebbei Shih,Liu and Ren,2009;Archaeopelecinus jinzhouensis Shih,Liu and Ren 2009;Cathaypelecinus daohugouensis Shih,Liu and Ren, 2009;Megapelecinus changi gen.et sp.nov.;Megapelecinus nashi gen.et sp.nov.; Eopelecinus huangi sp.nov.;Eopelecinus tumidus sp.nov.;Abropelecinus annulatus gen.et sp. nov.;Azygopelecinus clavatus gen.et sp.nov.;Shoushida regilla gen.et sp.nov.;The important critical characteristics of the genera and species are described.The specimens were examined with LAICA MZ 12.5 dissecting microscope and illustrated with the aid of a drawing tube attached to microscope and the software of Photoshop CS.All the type specimens described here are deposited in the College of Life Sxience,Capital Normal University in Beijing,China. |
