The genus name Plagiodontia means "oblique tooth", and derives from the two ancient greek words πλάγιος (plágios), meaning "placed sideways", and ὀδούς, ὀδόντος (odoús, odóntos), meaning "tooth".[1][2]
This genus contains the following three species (two of them extinct):
- Hispaniolan hutia (Plagiodontia aedium) F. Cuvier, 1836
- † Samaná hutia (Plagiodontia ipnaeum) Johnson, 1948
- † Plagiodontia spelaeum Miller, 1929
Within Capromyidae, Plagiodontia is the deepest branching genus, belonging to the tribe Plagiodontini. It is the sister group to the other genera Geocapromys, Mesocapromys, Mysateles and Capromys, all belonging to the tribe Capromyini.
