Two Eocene Okanagan Highlands fossils from the Klondike Mountain Formation at Republic, Washington were tentatively identified as Zacallites sp. by Standley Lewis (1992). However, redescription of the fossils by S. Bruce Archibald and Robert Cannings (2021) moved specimen UWBM 72289 to the dysagrionid genus Okanagrion and specimen SCSU7B-16 to the whetwhetaksid genus Whetwhetaksa.
