Plagiodontes is a recent genus of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Cyclodontinidae. ^{[2] [3]}

It occurs in tropical and sub-tropical regions of South America. ^[4]

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. ^{[5] [6] [7]}
