Two New Species of <i>Mesochorista</i> (Insecta, Mecoptera, Permochoristidae) from the Guadalupian Yinping Formation of Chaohu, Eastern China
Abstrak
Permochoristidae is a megadiverse mecopteran group that has mainly been reported from Russia and Australia, whereas records from China remain scarce. In this report, two new species of <i>Mesochorista</i> are described and illustrated from the Guadalupian Yinping Formation, Eastern China. <i>Mesochorista tillyardi</i> Lian and Huang, sp. nov. is characterized by the forewing covered with dense oval spots, and Sc<sub>1</sub> closely approximal to R<sub>1</sub> and connected by a short sc-r crossvein. <i>Mesochorista yinpingensis</i> Lian and Huang, sp. nov. is characterized by the forewing covered with dense irregularly colored patches, Sc<sub>1</sub> devoid of expanded area, and M with only five branches. Based on a detailed discussion of the type species and other co-occurring species of <i>Mesochorista</i> and <i>Permochorista</i>, in light of the new insights into Sc<sub>3</sub>, we support that <i>Permochorista</i> is a junior synonym of <i>Mesochorista.</i>
