C. galbinifrons galbinifrons
from northern Vietnam
The North Vietnam variant is distinguished by the nearly all black plastron, and dark underside of the marginals.
C. galbinifrons galbinifrons
from Hainan Island, China
The Hainana Island variant is characterized by the black plastron that has yellow markings which follow the seams.
Both geographical variations have dark medial bands on the carapace that fork at the front, leaving a lighter area behind the anterior marginal scutes. Both have thin, light stripes down the center of the vertebral scutes. Specific markings are highly variable in both cases. They are so similar that even the plastron differences cannot be relied upon to make the identification.
