It is endemic to the Pacaraima Mountains of southwestern Guyana,[3][4] although it is likely to also occur in the adjacent Roraima state of Brazil.

The skin of the dorsum, venter, and limbs is smooth but has scattered small tubercles.

Some specimens are darker and have more pale blue spots and more conspicuous tubercles on dorsum.

[2] The male advertisement call is a group of three soft, unpulsed, whistle-like notes.

Specimens have been found amidst leaf litter, among rootlets near the base of trees, and in ground holes covered by leaves.
