Plagiodontes Explained

Plagiodontes is a recent genus of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Odontostomidae.^{[1] [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.^[4] This same species has also been recorded from the Miocene of Uruguay and Miocene and Pleistocene of Argentina.^{[5] [6] [7]}

Species within the genus Plagiodontes include:

• Plagiodontes brackebuschii (Doering, 1877)
