Three new Odonata species (cf. Cephalozygoptera and cf. Dysagrionidae) from the early Eocene Okanagan Highlands of British Columbia, Canada, and Washington, United States of America

Three new species of Ypresian (early Eocene) Odonata are described: Paradysagrion sosbyae gen. and sp. nov. from the Klondike Mountain Formation at Republic, Washington, United States of America, and Dysagrionites allenbyensis sp. nov. and Allenby gen. and sp. A from the Allenby Formation near Princeton, British Columbia, Canada. All three are assigned to the Dysagrionidae and Cephalozygoptera but only tentatively, as key diagnostic morphology is missing from their incomplete fossils. The definition of the collective genus Dysagrionites is broadened to include odonates tentatively assigned to the Dysagrioninae (Dysagrionidae) that are distinct as species but have unclear nominal genus affinity.
