A new species of Archaeochrysa Adams (Neuroptera: Chrysopidae) from the early Eocene of Driftwood Canyon, British Columbia, Canada

  • S. Bruce Archibald (a1) (a2) (a3) and Vladimir N. Makarkin (a4)

Archaeochrysa sanikwa new species (Neuroptera: Chrysopidae: Nothochrysinae) is described from early Eocene (Ypresian) Okanagan Highlands shale at Driftwood Canyon, British Columbia, Canada. The evolutionary trends of three chrysopid wing venation characters (the shape of the intramedian cell, the position of the crossvein 2m-cu, and the development of the pseudocubitus) are analysed. The forewing venation of this species is very plesiomorphic compared with the vast majority species of Nothochrysinae, both fossil and extant.
