Pomatiopsis is the type genus of the family Pomatiopsidae.[1]
Distribution
editThe distribution of the genus Pomatiopsis includes the USA: West Coast of the United States, Midwestern United States and Eastern United States.[3]
Description
editIn 1862, the American malacologist George Washington Tryon first defined this genus.[2] Tryon's diagnosis reads as follows:[2]
Shell elongate, the spire (of about six whorls) much exceeding the length of the aperture.
Species
editThere are four[3] species within the genus Pomatiopsis:
- Pomatiopsis binneyi Tryon, 1863[3]
- Pomatiopsis californica Pilsbry, 1899[3]
- Pomatiopsis chacei Pilsbry, 1937
- Pomatiopsis cincinnatiensis (Lea, 1840)[3]
- Pomatiopsis hinkleyi Pilsbry, 1896
- Pomatiopsis lapidaria (Say, 1817) - type species[3]
Ecology
editSpecies in the genus Pomatiopsis are amphibious, living in humid habitats, on marshy ground and in periodically flooded soil (Pomatiopsis californica and Pomatiopsis lapidaria), in trickling water (Pomatiopsis binneyi) and on mud of streams (Pomatiopsis cincinnatiensis).[3]
