The purpose of this application, under Articles 23.9.5 and 23.10 of the Code, is to conserve the specific name of Arion (Carinarion) fasciatus (Nilsson, 1823) (arionidae), originally published in the combination Limax fasciatus as a primary homonym of Limax fasciatus Razoumowsky, 1789 (limacidae). The two names have not been considered congeneric since the 19th century. We propose to conserve the name Limax fasciatus Nilsson, 1823, by ruling that the name is not invalid by reason of being a junior primary homonym.
