It is native to North America.[2]

A 2009 phylogenetic analysis of genus Vertigo revealed that many of its species should be included in the circumscription of V. arthuri.[6] This greatly expanded the range of V. arthuri, which is now considered to have a disjunct distribution spanning from Alaska to Newfoundland to New Mexico.[2] V. arthuri now includes many snails that were formerly considered to be rare local endemics of the American Midwest.[6] It now has one of the largest ranges of any land snail in the Western Hemisphere.[2]

In many areas, this snail lives in various types of forest habitat. It consumes leaf litter and organic layers on rock surfaces.[2]

Description

(Described as Vertigo gouldii hubrichti) The shell is subcylindric, larger than Vertigo nylanderi Sterki, 1909 with a similar long and deep impression over the palatal folds. The lower-palatal is deeply immersed. There is no angular lamella. The basal fold is well developed. The intermediate whorls are strongly, sharply striate
