A small species of frog reaching up to 2 cm in body length. It has a brown back, with darker brown spots. The lower half of the sides of the body and head are bluish-grey. There are white spots along the upper lip. The belly is white, with grey specks. The pupil is horizontal, and the iris is gold. The groin and the backs of the thighs are orange-red. Fingers are unwebbed and toes are slightly webbed, both without discs.
Eggs, tadpoles, and development time are unknown, but are likely to be similar to those of other Uperoleia species. Breeds during summer to autumn in the wet season.
Looks very similar to Uperoleia crassa, Uperoleia borealis, Uperoleia inundata, and Uperoleia minima in its distribution, but is smaller than all these species except Uperoleia minima, which has a different call.
