Exploration of phylogeography of Monacha cantiana s.l. continues: the populations of the Apuan Alps (NW Tuscany, Italy) (Eupulmonata, Stylommatophora, Hygromiidae)

Two new lineages CAN-5 and CAN-6 were recognised in four populations of Monacha cantiana (Montagu, 1803) s.l. from the Italian Apuan Alps by joint molecular and morphological analysis. They are different from other M. cantiana lineages known from English, Italian, Austrian and French populations, i.e. CAN-1, CAN-2, CAN-3 and CAN-4, as well as from the other Italian Monacha species used for comparisons (M. parumcincta and M. cartusiana). Although a definite taxonomic and nomenclatural setting seems to be premature, we suggest that the name or names for these new lineages as one or two species should be found among 19th century names (Helix sobara Mabille, 1881, H. ardesa Mabille, 1881, H. apuanica Mabille, 1881, H. carfaniensis De Stefani, 1883 and H. spallanzanii De Stefani, 1884).
