Revision of the two small damselflies Eopodagrion scudderi Cockerell, 1921 and Eopodagrion ‘Podagrion’ abortivum (Scudder, 1878) (Odonata, Zygoptera) from the lower Eocene of Green River Formation (USA)
Two early Eocene damselfly taxa Eopodagrion scudderi Cockerell, 1921 and Eopodagrion ‘Podagrion’ abortivum (Scudder, 1878) are redescribed and refigured. Their phylogenetic relationships are discussed. Although they could likely belong to the Coenagrionidae, their exact affinities remain uncertain because of the presence of homoplasies affecting crucial characters among the Zygoptera.
