Distribution

Vertigo pseudosubstriata was first identified as a Pleistocene fossil in the Weichselian loess of Dolní Věstonice (Moravia, Czech Republic).[1] Further Pleistocene evidence followed in Central Europe.[1]

The first indications of recent occurrences of the species in the Tien Shan were submitted by Matěkin.[2][1] Uvalieva (1967)[4] discovered the species anew in the Southern Altai Mountains and initially described it as Vertigo laevis (synonym).[1] 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.[1]

The recent distribution of Vertigo pseudosubstriata includes:

Shell description

The shape of the shell is cylindrical-ovate.[2]
