This was the only yellow treefrog I saw at Bobiri Forest Reserve. I believe that it is the namesake treefrog of this forest, but I haven't been able to get this belief confirmed.

Ghana frog expert Caleb Ofori Boateng did confirm the IDs of these (except the last one, which he only suspected was H. bobirensis because the angle wasn't good enough to be sure).

Caleb also confirmed the ID of this one.
