A small species of frog reaching up to 2.5 cm in body length. It has a brown or grey-brown back, with darker patches. There is sometimes a small, pale yellow-white stripe from the edge of the mouth to the arm. The tops of the arms at the shoulders are pale yellow. The belly is white with brown spots, and the male has a brown throat. The under-surfaces of the legs are purple-pink. The pupil is nearly round, and the iris is gold. The groin and the backs of the thighs are bright orange. Fingers and toes are unwebbed, both without discs. The parotoid glands are large and often the same colour as the back.
Eggs, tadpoles, and development time are unknown, but are likely to be similar to those of other Uperoleia species. Possibly breeds during summer to autumn in the wet season.
Looks very similar to Uperoleia aspera, Uperoleia borealis, Uperoleia crassa, Uperoleia inundata, and Uperoleia micra in its distribution, but has a different call.
