Vitrea transsylvanica explained

Vitrea transsylvanica is a species of small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Pristilomatidae.^[1]

Description

The shell is small: 1.3-2.2 mm x 3.0-4.5 mm.

The body whorl is more inflated than in Vitrea subrimata and Vitrea subcarinata. The width, as seen from above, is around 2.3-2.6 times that of the penultimate whorl. The first whorls are denser arranged than in Vitrea subrimata. The aperture, as seen from above, is weakly curved (Nautilus-like protruded). There is no umbilicus

This species differs from Vitrea diaphana in its wider body whorl and its Nautilus-like protruded aperture (in Vitrea diaphana straight).^[2]

Distribution

This species occurs in:

• Czech Republic
• Ukraine^[3]

The species occurs in closed forests, mainly in beech forests.
