Vespericola is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.

Habitat

[edit]

These snails are found along the Pacific Coast of North America, from southern Alaska and British Columbia to California.

Shell description

[edit]

The shells of these small to medium, globose or depressed globose snails are usually some shade of brown, sometimes without apertural teeth and sometimes with a single tooth on the parietal wall. Small periostracal hairs may be observed on the shell surface of many specimens, but the shells otherwise resemble those of Praticolella or Mesodon.[2]

Anatomy

[edit]

According to Pilsbry (1940), Vespericola "differs from all other Polygyridae by the possession of a well-developed though rather short verge, and by the peculiar shape of the epiphallus".[3]

Species

[edit]

Species within the genus Vespericola include:[2][4]
