Well, it is possible that they occur in the Northern part of Hainan. However, I am very surpirse that none of them is available in the trade! I mean you can find almost all rare Chinese reptiles if you have the right connection, but not in the case of G. bawanglingensis.
Brian. Do you know anybody is keeping them or even have a preserved specimen?
It is definatly the species any Goniurosaurus lovers would love to have.
