The purpose of this application under Article 75.6 of the Code is to conserve the specific names of the European ‘Small Apollo’ butterfly Parnassius phoebus (Fabricius, 1793) and the Altai ‘Apollo’ butterfly Parnassius ariadne (Lederer, 1853) in their current usage. Hanus & Theye (2010) discovered that the traditional concept of the name P. phoebus was a misidentification and published actions contrary to Art. 75.6. We herein request that the International Commission on Zoological Nomenclature use its plenary power to set aside all previous type fixations for the nominal species Papilio phoebusFabricius, 1793, and to designate a neotype representative of the current usage of P. phoebus.
