Pupilla triplicata is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusk or micromollusk in the family Pupillidae.
Distribution
The distribution of this species is central-European and southern-European[2] and includes southern Europe from the Pyrenees to the Alps, the Carpathians, Crimea, northern Turkey, Transcaucasia and central Asia to Lake Baikal.[3]
The species occurs in a number of countries including:
- Lower concern in Switzerland[3]
- Endangered in Germany,[3] extinct in Rheinland-Pfalz[3]
- Vulnerable in Austria[3]
- Czech Republic
- Slovakia
- Poland
- Ukraine[4]
Pupilla triplicata has a scattered distribution, and populations in lower altitudes are threatened by habitat destruction.[3]
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]
