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:

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]

gollark: Switches, unless they're at stupidly high temperature?
gollark: They could kill the coronavirus by firing relativistic protons at it.
gollark: Star Trek isn't *remotely* realistic, so almost certainly not as they portray it. The closest vaguely plausible thing is probably the Alcubierre drive, which IIRC could maybe exist, isn't remotely practical, and comes with its own exciting problems.
gollark: They can't be conveniently converted to metres or... anything, really, and don't work with SI prefixes.
gollark: Miles are still an awful unit even if you're used to them.
