Vertigo arthuri
Template:Short description Template:Use dmy dates Template:Speciesbox
Vertigo arthuri is a species of land snail in the family Vertiginidae, the whorl snails. It is known by the common names callused Vertigo,[1] or Midwest Pleistocene Vertigo.[2]
It is native to North America.[3]
A 2009 phylogenetic analysis of genus Vertigo revealed that many of its species should be included in the circumscription of V. arthuri.[5] 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.[3] V. arthuri now includes many snails that were formerly considered to be rare local endemics of the American Midwest.[5] It now has one of the largest ranges of any land snail in the Western Hemisphere.[3]
In many areas, this snail lives in various types of forest habitat. It consumes leaf litter and organic layers on rock surfaces.[3]
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
