title: New fossil mesoserphid wasps (Insecta, Hymenoptera, Proctotrupoidea) from the Jehol Biota, China.
abstract: A new genus with two new species, Codoserphus calophlebius gen. et sp. nov. and Codoserphus euneurus gen. et sp. nov., assigned to the subfamily Mesoserphinae of Mesoserphidae, are described from the Jehol Biota, Early Cretaceous Yixian Formation of Huangbanjigou Village in Liaoning, China.
