The Clausiliidae (Gastropoda) of the Maltese Islands, some additional data

Lampedusa (Muticaria) syracusana from near Syracuse on the island of Sicily is specifically distinct from the polytypic L. (M.) macrostoma, occurring on the Maltese Islands. The former species is not known from the Maltese Islands. Most probably the four subspecies of L. (M.) macrostoma did evolve from a single ancestral form. To stabilize the nomenclature as good as possible lectotypes are selected for both Lampedusa (Muticaria) species and some problems with spelling of names and dates of publication are dealt with.
