Plagiodontes is sometimes considered a subgenus in the genus Cyclodontina. 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]

  • Plagiodontes brackebuschii (Doering, 1877)
  • Plagiodontes daedaleus (Deshayes, 1851)
