Two new species of Nevania Zhang & Rasnitsyn 2007, Nevania perbella sp. nov. and Nevania aspectabilis sp. nov., are described and illustrated. They are assigned to Nevania based on their unique morphological characters: forewing venation complete; 2A complete; metasoma with first and second segments long and tube-like. A key to the known species of Nevania is provided. These fossils, collected from the Jiulongshan Formation (Middle Jurassic) of Daohugou in Inner Mongolia, China, broaden the known diversity of this genus in mid-Mesozoic ecosystems. 相似文献
