Stabilizing the nomenclature of fabrican names of north American hairstreaks (Lycaenidae: Theclinae: Eumaeini)

Four actions are taken to preserve nomenclatural stability of Nearctic hairstreak names proposed by Fabricius. Following the provisions of ICZN Article 23.9.1, Thecla liparops Le Conte, 1833 is made a nomen protectum and Hesperia anacreon Fabricius, 1793 is made a nomen oblitum. Thecla m-album Boisduval & Le Conte, 1833 is made a nomen protectum and Hesperia euripides Fabricius, 1793 is made a nomen oblitum. Lycus niphon Hübner, [1819] is made a nomen protectum and Hesperia plautus Fabricius, 1793 is made a nomen oblitum. The name Hesperia cecrops Fabricius, 1793 cannot be determined definitively from the original description and might apply to different biological species. We designate a neotype for Hesperia cecrops Fabricius, 1793 following the provisions of ICZN Article 75.3, with the new type locality of Savannah, Georgia, USA. New information on the identity of Papilio mars Fabricius, 1776 and Hesperia titus Fabricius, 1793 is consistent with current usage. The identity of Hesperia columella Fabricius, 1793 was corrected previously, and Papilio ixion Fabricius, 1775 remains a nomen dubium.
