Vertigo arthuri

Vertigo arthuri is a species of land snail in the family Vertiginidae, the whorl snails. It is known by the common name callused vertigo. It is native to North America. A 2009 phylogenetic analysis of genus Vertigo revealed that many of its species should be included in the circumscription of V. arthuri. 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. V. arthuri now includes many snails that were formerly considered to be rare local endemics of the American Midwest. It now has one of the largest ranges of any land snail in the Western Hemisphere.
