Plagiodontes is a recent genus of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Odontostomidae.[2] Plagiodontes is sometimes considered a subgenus in the genus Cyclodontina. It occurs in tropical and sub-tropical regions of South America.[3]
Fossil record
The fossil record of Plagiodontes extends back to the Brazilian Paleocene, with a supposed specimen of Plagiodontes dentatus found in Itaboraí Basin.[1] This same species has also been recorded from the Miocene of Uruguay and Miocene and Pleistocene of Argentina.[4][5][6]
Species
Species within the genus Plagiodontes include:
- Plagiodontes dentatus (Wood, 1828) - fossil from Brazil, Uruguay and Argentina, recent from Argentina - type species of genus
- Plagiodontes trahyrae - from Brazil
