Head Of The Chinese Northern Mesozoic Chief Wings Fossil Insects

Eastern Inner Mongolia and Western Liaoning are located in the Northeast part of China. This is one of the most typical aeras 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 Amphiesmenopteran(Trichoptera and Lepidoptera) from North China.Firstly,the researching history on Trichoptera and Lepidoptera is provided.Secondly,the morphology and biology are reviewed.3 genera 5 species of Order Trichoptera and 1 new genus 1 new species of Order Lepidoptera are described and illustrated in this paper.They are listed as following:Sinomodus Wang & Ren,2009:S.spatiosus Wang & Ren,2009,S.peltatus Wang & Ren,2009,S. macilentus Wang & Ren,2009;Multimodus Sukatsheva,1968:Multimodus disstitus Ren,1995,Multimodus venus Wang sp.nov.;Juraphilopotamus gen.nov.:Juraphilopotamus lubricus Wang gen.et sp.nov.;Sinolepidopterix Wang,Labandeira et Ren gen.nov.:Sinolepidopterix shihi Wang,Labandeira et Ren gen.et.sp.nov..The distribution of Family Vitimotauliidae are proposed and the variability of the wing venation of this family is discussed for the first time;the geographical distribution of fossil Philopotarnidae is discussed also.In addition,the morphological characters,origin and evolution,phylogenetic and geographical distribution of early lepidopteran are proposed.The important critical characters of these 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 CorelDraw 12.All the type specimens described here are deposited in the College of Life Science,Capital Normal University in Beijing,China.
