| Abstract |
Crisilla perminima (Manzoni, 1868), a diminutive rissoid species living in Canary and Selvagens Islands (NE Atlantic), was reported from Sardinia. Based on the analyses of further material from Canary Islands and the Mediterranean Sea, as well as photographic comparisons by SEM, the Sardinian record is assigned to Alvania simulans Locard, 1886 which shows a certain degree of variability in sculpture and colour of the shell. Crisilla perminima is thus excluded from the Mediterranean malacofauna. The external soft parts of A. simulans are described for the first time and its taxonomic placement is discussed. |
