Undescribed specimens are known from the Cenomanian aged Burmese amber of Myanmar,^[2] and several of the Eocene Okanagan Highlands sites. Fossils identified as Eosphecium sp. have been reported from the Driftwood shales, Tranquille Formation, and Klondike Mountain Formation. Additional angarosphecid specimens are reported from the Tranquille and Republic sites plus the Allenby Formation that are not 'Eosphecium.^[3] Burmasphex Melo and Rosa (2018) and Decasphex Zheng et al (2020), originally assigned to this family, were subsequently moved to the separate apoid family Burmasphecidae.
