Mauremys is a genus of turtles 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, M. japonica
- Yellow pond turtle, M. mutica
- Vietnamese pond turtle or Annam leaf turtle, M. annamensis - formerly separated in Annamemys
- Caspian turtle or striped-neck terrapin, M. caspica
- Balkan pond turtle or Balkan terrapin, M. rivulata - formerly included in M. caspica
- Spanish pond turtle, M. leprosa - formerly included in M. caspica
- Chinese broad-headed pond turtle, M. megalocephala
- Red-necked pond turtle, M. nigricans
- Chinese pond turtle, M. reevesii
- Chinese stripe-necked turtle, M. sinensis
The Fujian pond turtle, described as Mauremys iversoni, is a farm-bred hybrid, between yellow pond turtles (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.
