ABSTRACT Eomerope macabeensis sp. nov. (Mecoptera: Eomeropidae) is described from the Early
Eocene (Ypresian) McAbee locality in British Columbia, Canada. This is the ̃rst record of the family
Eomeropidae in the Okanagan Highlands fossil deposits of British Columbia (Canada) and Wash-
ington state (United States). Previously known Cenozoic occurrences of the family include Eomerope
tortriciformis Cockerell 1909 from the Eocene of Florissant, CO; Eomerope pacifica Ponomarenko &
Rasnitsyn 1974 from the Paleocene Tadushi Formation., and Eomerope asiatica Ponomarenko &

to E. asiatica. Where environmental parameters are known, these occurrences are mostly from
highlands, with upper microthermal to mid-mesothermal climates and mild winters. N. reedi is
phytophagous or saprophagous. Although Cenozoic Eomeropidae are associated with Fagus, Notho-
fagus, or Fagopsis-dominated forests in the Western Hemisphere, the Fagaceae and Nothofagaceae are
