Leaf-mimicking katydids from the Middle Miocene of Yunnan, southwestern China (Orthoptera: Tettigoniidae)


The first fossil leaf-mimicking katydids from the eastern Palaearctic are described and attributed to the genus Archepseudophylla under the names Archepseudophylla nanzhaoica sp. nov. and Archepseudophylla wenshanensis sp. nov., both from the Early to Middle Miocene strata in Wenshan, Yunnan, southwestern China, which is the core of the southwestern China karst region. This pseudophylline genus was previously known only from the Eocene–Oligocene of Europe, and is indicative of warm temperate to subtropical paleoclimatic conditions within the Yunnan region during this stage of the Miocene.
