Abstract:
Pseudotettigonia leona sp.n. is described from a single left forewing collected from the Middle Eocene Kishenehn Formation in northwestern Montana, U.S.A. P. leona is the second of only two fossil macropterous Tettigoniidae that preserve an intact stridulatory apparatus. The subfamily Pseudotettigoniinae is reexamined. The specific epithet bricei is assigned to the late Miocene fossil tettigoniid Tettigonia bricei sp.n., originally described as the extant Tettigonia viridissima.This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:E69E83CE-9046-4BBD-AA11-E0AD0C382700.
