Vitrea subrimata

The shell is small: 1.3-2.2 mm x 2.5-5 mm (diameter 2.6-2.7 mm at 3 whorls, 3.5-3.8 mm at 4 whorls)

The shell is colourless and transparent. It contains 4-5 whorls. The width of the body whorl as seen from above is 1.2-1.7 times that of the penultimate whorl. The umbilicus is very narrow but is present (difference to Vitrea diaphana). The columellar margin is pointed and slightly protruded and covers the umbilicus only very weakly. The shell is very variable, except the characteristic form of the columellar margin at the umbilicus. The morphological variation has been associated with subspecies, but the nature of the variation is not yet understood. Two forms may co-occur with and without intermediates, other populations may consist of only one single form.[4]

Distribution in Europe of Vitrea subrimata

The distribution of this species is alpine and southern-European.[5]

This species occurs in countries and islands including:

• Czech Republic
• Ukraine[6]
• Great Britain, notably the Great Asby Scar.[7]

This species can be found in humid mountain forests under leaf litter, stones or in crevices, usually on calcareous substrate, rocks and rock rubble, up to 2600 m. In Bulgaria it is recorded from 2000 m, in England also in open habitats, between 250 and 600 m.
