Comment on the proposed conservation of Cylindrus Fitzinger, 1833 (Mollusca, Gastropoda, HELICIDAE)

摘要

Cylindrus was introduced by Fitzinger as new genus name for the Helicid snail species first described as Pupa obtusa by Draparnaud 1805. Cylindrus was then used in a number of publications and lists for the monotypic species Cylindrus obtusus. This combination was used in all important publications about the Alpine endemic C. obtusus. Furthermore, the name Cylindrus describes the shell form, one of the remarkable traits of this species, in a vivid way. On the other hand, as Gittenberger states, the senior synonyms Cylindrus Batsch, 1789, and Cylindrus Deshayes, 1824 are either not in correct or not in regular use. Besides, Puilllandre et al. (2015) favour the use of Cylinder Montfort, 1810 for the respective Conidae species related to Conus textile Linnaeus, 1758. They declared, independently from the current application, that the names Cylinder Montfort, 1810 and Cylindrus Fitzinger, 1833 should be preserved to maintain stability in nomenclature. This implies that the use of Cylindrus Fitzinger, 1833 would also not affect the nomenclature of Conidae. We therefore support the application of Gittenberger.
