[1] The specific name parkeri honors Hampton Wildman Parker, an English zoologist and herpetologist.

One form is dorsally dark greyish brown, usually with black areas overlying the dermal ridges.

The second color morph is otherwise similar but has a narrow yellow or orange vertebral stripe superimposed on the previous pattern.

Mature males have a subgular vocal sac, grey nuptials pads, and many tiny spinules on the throat and the chest.
