Hodges Number
Synonyms and other taxonomic changes
Euphyia unangulata of Europe was previously thought to be holarctic, and the name was therefore also applied to the North American taxon. Scoble et al in Geometrid Moths of the World (1999) split them into distinct species, and the correct name for the North American taxon is E. intermediata. See comments here.
