Comment on the proposed conservation of the specific names of Limax fasciatus Razoumowsky, 1789 (LIMACIDAE) and Limax fasciatus Nilsson, 1823 (currently Arion fasciatus, ARIONIDAE) (Gastropoda, Stylommatophora)

摘要

The commonly used name Arion fasciatus (Nilsson, 1823), originally Limax fasciatus, is a junior primary homonym of the dubious and hardly used name Limax fasciatus Razoumowsky, 1789. Falkner et al. (2002, p. 141) declared Limax fasciatus Razoumowsky, 1789 a nomen oblitum in accordance with Article 23. 9. 2 of the Code with the aim of preserving the current usage of the name Arion fasciatus (Nilsson, 1823). Von Proschwitz & Falkner demonstrated that this action had been taken in error, because the conditions of Article 23. 9. 2 of the Code were not met. The name Limax fasciatus Razoumowsky, 1789 has been used at least twice after 1899. Thus, they referred the case to the Commission in accordance with Article 23. 10 of the Code. Contrary to the intention of Falkner et al. (2002, p. 141), von Proschwitz & Falkner asked the International Commission on Zoological Nomenclature to rule that priority of Limax fasciatus Razoumowsky, 1789 be maintained and to place both, Limax fasciatus Nilsson, 1823 and Limax fasciatus Razoumowsky, 1789 on the Official List of Specific Names in Zoology. The reason for their shift of opinion concerning Limax fasciatus Razoumowsky, 1789 was that 'from preliminary results it seems very likely that this early name for an alpine Limax needs to be revalidated' and that 'Up to now no other available names which could potentially be applied to Razoumowsky's Limax species have been identified'.
