Ocadia is a genus of turtle in the family Geoemydidae (formerly called Bataguridae). It is sometimes included in Mauremys.[1] It contains the following species:
O. sinensis is known to hybridize with most other Geoemydidae.[2] Hybridization runs rampant in that family; while it is possible that perfectly valid species could arise this way, the other Ocadia 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 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 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.
