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

摘要

I fully support the request by Gittenberger & Bank (BZN 72: 269–273). In my European non-marine mollusc species identification guide (Welter-Schultes, 2012, p. 586) I listed both Cylindrus and Cochlopupa as candidate generic names for Pupa obtusa Draparnaud, 1805 and remarked that Cylindrus was preoccupied. Making use of a disclaimer I did not use either one of the two generic names as valid in the sense of the Glossary. I wrote ‘if nothing else interferes I would suggest using Cochlopupa’. The option proposed by Gittenberger & Bank to ask the Commission for a solution is better than my own proposal because the usage of Cylindrus is much more widespread and the request is in the sense of maintaining the stability of names. Cylindrus obtusus is a well-known species in Austria, often used in the literature. Gittenberger & Bank’s efforts in researching the situation in the marine group involved and for thoroughly checking out other possible circumstances should be acknowledged by approving their proposed solution.
