Mauremys is a genus of turtle in the family Geoemydidae (formerly called Bataguridae). Ocadia and Chinemys are included here by some scientists, but not by the majority nor by hobbyists.
Species include:
- Japanese pond turtle, Mauremys japonica
- Yellow pond turtle, Mauremys mutica
- Vietnamese pond turtle or Annam leaf turtle, Mauremys annamensis - formerly separated in Annamemys
- Caspian turtle or Striped-neck terrapin, Mauremys caspica
- Balkan pond turtle or Balkan terrapin Mauremys rivulata - formerly included in M. caspica
- Spanish pond turtle Mauremys leprosa - formerly included in M. caspica
The Fujian pond turtle, described as Mauremys iversoni, is a farm bred hybrid, between Yellow pond turtle (usually females) and the Golden coin turtle or Cuora cyclornata (usually males). Similarly, the turtles described as Mauremys pritchardi are farm bred and wild occurring hybrids between the Chinese pond turtle and the Yellow pond turtle. While it is not unusual for valid species of geoemydid turtles to arise from hybrids, this is yet to be discussed with M. pritchardi, M. iversoni is probably not, since they only seem to be produced in farms and most males are sterile.
