Vitrea subrimata is a small, air-breathing land snail species, a terrestrial pulmonate gastropod mollusk in the family Pristilomatidae.[3]
- Subspecies
- Vitrea subrimata litoralis (Clessin, 1877)
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 (different from Vitrea diaphana). The columellar margin is pointed and slightly protruding, covering the umbilicus very weakly. The shell is very variable, except for 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 form.[4]
