Notes

Shell small, grossly stubby and cylindrical; spire with 7-9 coils; four teeth are visible in the aperture, at different levels of development; peristome white; colour beige. Samples were collected on sandy soils beside the road to Monte Adone, at the surface, as well as in underbrush upstream to the road, near Campiuno. This subspecies inhabits calcareous soils and lives on grass and shrubs in sunny areas, as well as under rocks, in crevices and on screes ( Cossignani and Cossignani 1995). Calcareous soils are populated by this subspecies from the plain to the mountain levels, in xeric environments, less commonly on grassy and shrubby vegetation ( Kerney and Cameron 1979). It tolerates extensive grazing and can be found in sheep and goat pastures, up to 2,400 m a.s.l. in the Alps ( Welter-Schultes 2012). It was also reported as a Pleistocene fossil from Varazze (Savona, Italy; Boato et al. (1984)).
