Siciliaria (Siciliaria)

Nomenclatural note: Clausilia decollata and C. deshayesii Potiez & Michaud 1838 are unidentified species. The first may
be S. grohmanniana, the second S. septemplicata or S. calcarae. Three „species“ of Benoit (1882) are also unidentified:
C. trinacliana (misprint for trinacriana) (= S. calcarae?), C. rubra (= S. septemplicata?) and C. subdiaphana (= S.
grohmanniana?). The variety names published by Monterosato, in fact infrasubspecific, are not considered in this article.
