Distribution and taxonomic notes.

Adscita geryon geryon is distributed from the Iberian Peninsula and Britain to European Russia, the Crimea and Turkey. Leraut (2012: 61) reinstated the nominal taxon Adscita geryon aeris (Verity, 1946) as valid and on the following page newly described a subspecies from the Paris region. It is acknowledged that Adscita geryon is an extremely variable species, both in phenotype and genitalic morphology, but we see no justification for recalling a subspecies from synonymy, where it was placed by Efetov and Tarmann (1999: 28, 2012: 31), or in describing a new subspecies from France. Accordingly, both taxa are here formally placed as synonyms (syn. rev.; syn. n.) of the nominotypical subspecies Adscita geryon geryon .
