O. sinensis is known to hybridize with most other Geoemydidae genera.[2] Hybridization runs rampant in that family; while it is possible that perfectly valid species could arise this way, the other Ocadia species are apparently only known from a few specimens each, all of them purchased from a turtle dealer in Hong Kong: The supposed species "Ocadia glyphistoma", described by Mccord & Iverson in 1994{{Citation needed|date=December 2008}} and supposedly from southern Guangxi and northern Vietnam, is a hybrid between a male O. sinensis and a female Vietnamese pond turtle (Mauremys annamensis).[3] This "species" seems to be naturally occurring in central Vietnam, but is occasionally also bred for the pet trade in southern Chinese turtle farms.[4] Philippen's striped turtle ("Ocadia philippeni"), described by Mccord & Iverson in 1992{{Citation needed|date=December 2008}} and said to occur on Hainan, also proved to be a hybrid, between a male O. sinensis and a female Cuora trifasciata.[5] It is not proven but likely that this "species" also originates from both the wild and is bred in farms. In 2013, a Miocene Japanese fossil species of the same genus was described, Ocadia tanegashimensis Takahashi & al.,[6] which adds itself to the already known Pleistocene O. nipponica, from the same country.
