Centralian Tree Frog, Litoria gilleni
The Centralian Tree Frog (Litoria gilleni) is a large species of tree frog endemic to a small area in central Australia. It is closely related to the Australian Green Tree Frog (L. caerulea), and looks much alike it in appearance.
As a large tree frog, it reaches a length of 3.1 inches in the females and 2.4 inches in the males. The dorsal surface is green or olive green, while the ventral surface is white. A large fold covers the top part of the tympanum, which is visible. The toe pads are large, the feed are webbed, and the hands are one-third webbed. The only physical feature which can distinguish the Centralian Tree Frog from the Australian Green Tree Frog is the number of white spots on the dorsal surface.
The habitat of the frog is rock gorges with water holes, either permanent or temporary. It will hide during the day underneath rocks, and hunt and mate during the cooler night. Its call is a slow barking call, much like that of the Australian Green Tree Frog.
It lives in the MacDonnell Ranges in central Australia. This confined distribution isn’t inhabited by the Australian Green Tree Frog, which allows easy identification.
