Newly identified giant lacewings show unique wing patterns from the Okanagan Highlands, suggesting evolutionary significance.
Two new species of giant lacewings (Neuroptera: Polystoechotidae) are described from Ypresian Okanagan Highlands localities in western North America: Palaeopsychops goodwini sp. nov. and Palaeopsychops barthae sp. nov. , both from Republic, Washington, United States of America, and a less well-preserved specimen is treated as Palaeopsychops sp. indet., the first occurrence of the family at McAbee, British Columbia, Canada. These share distinctive wing colouration – dark with a single pale, broad fascia mid-wing.
