Orthoptera Hagloidea Stenopelmatoidea Ypresian Cenozoic Quilchena Republic


We revise the subfamily Zeuneropterinae (Orthoptera, Ensifera) and treat it as the family Palaeorehniidae Zeuner stat. nov. We restore the late Eocene Palaeorehnia Cockerell from Florissant, Colorado, USA to the taxon and describe two new genera and species in it: Ypopteron nicola n. gen., n. sp. from Quilchena, British Columbia, Canada and Republicopteron douseae n. gen., n. sp. from Republic, Washington, USA. Given current knowledge, Palaeorehniidae appears intermediate between the Stenopelmatoidea and the Hagoidea (s.s.).
