Description

A medium-sized species of frog reaching up to nearly 4 cm in body length. It has a grey or brown back, with darker patches and an indistinct, orange longitudinal stripe along the middle of the back. There are sometimes orange spots also. There is sometimes a small, pale orange-white stripe from the edge of the mouth to the arm. The belly is white with tiny brown specks, and the male has a dark brown throat. The pupil is horizontal, and the iris is gold. There is sometimes a small orange spot on the back of each thigh. Fingers are unwebbed and toes are three-quarters webbed, both without discs. The parotiod glands, glands in the groin, and glands on the lower back are large and brown or pale orange-brown.

Breeding Biology

Eggs, tadpoles, and development time are unknown, but are likely to be similar to those of other Uperoleia species. The eggs are probably laid under the surface of the water in temporary ponds and creek pools. Breeds during summer to autumn in the wet season.

Similar Species

Looks similar to Uperoleia glandulosa, Uperoleia russelli, and Uperoleia talpa in its distribution, but has a different call to Uperoleia glandulosa and Uperoleia russelli, and smaller parotoid glands than Uperoleia talpa.
