The Fujian pond turtle, described as Mauremys iversoni, is a farm-bred hybrid, between yellow pond turtles and the golden coin turtle or Cuora cyclornata. 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.
