The species occurs in a number of countries including:

Description

The shell of Pupilla triplicata is much smaller than Pupilla sterrii and the other Pupilla species.[3] The structure of the surface is finer.[3] Whorls are convex.[3] The cervical callus is present but not extremely strong.[3] There are usually 3 teeth in the aperture.[3]

The height of the shell is 2.2-2.8 (up to 4) mm.[3] The width of the shell is 1.4 mm (shell diameter should not exceed much 1.4 mm).[3]

Ecology

Pupilla triplicata lives in grass near limestone rocks, in dry and sunny habitats, often in limestone rock rubble with xerophilous vegetation.[3] It lives mainly between 300 and 1000 m, and in Switzerland up to 2600 m in altitude.[3]
