Vertigo pseudosubstriata is a species of minute, air-breathing land snail, a terrestrial pulmonate gastropod mollusc or micromollusk in the family Vertiginidae, the whorl snails.
Distribution
Vertigo pseudosubstriata was first identified as a Pleistocene fossil in the Weichselian loess of Dolní Věstonice (Moravia, Czech Republic). Further Pleistocene evidence followed in Central Europe.
The first indications of recent occurrences of the species in the Tien Shan were submitted by Matěkin. Uvalieva (1967) discovered the species anew in the Southern Altai Mountains and initially described it as Vertigo laevis (synonym). In recent times to date, this species has been found in the Tien Shan, Altai Mountains, Pamir Mountains and Himalayas where it is relatively widespread in their alpine altitudes.
The recent distribution of Vertigo pseudosubstriata includes:
Pakistan
Kazakhstan
Shell description
The shape of the shell is cylindrical-ovate.
The width of the shell is 1.2 mm; the height of the shell is 2.1-2.2 mm.
