Gluphisia septentrionis, stat. rev. Synonymized with G. crenata by Schintlmeister ([1984]), who presumed crenata to be a widespread Holarctic species. However, an unexpectedly large genetic divergence (~8% of COI mtDNA barcode fragment) between North American and European populations indicates that separate species status should be retained until a more complete taxonomic evaluation can be made.
