Description

A small species of frog reaching up to 2.5 cm in body length. It has a brown, brown-orange or brown-grey back, with or without darker patches and spots. There is often a V-shaped marking between the eyes. The belly is white, with grey specks. The pupil is nearly round, and the iris is gold. The groin and the backs of the thighs are bright red. The legs have horizontal bars. Fingers and toes are unwebbed, both without discs. The parotoid glands are large, and either orange-brown or the same colour as the back.

Breeding Biology

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.

Similar Species

Looks very similar to Uperoleia mjobergii, Uperoleia minima, Uperoleia aspera, and Uperoleia borealis in its distribution, but has rougher skin. Also looks similar to Uperoleia trachyderma in its distribution, but lacks orange spots on its back and has a slightly different call.
