Description

A small species of frog reaching up to 3 cm in body length. It has a brown or grey-brown back, with dark brown patches and sometimes a thin, orange longitudinal line along the middle. There is also sometimes a small, pale brown-yellow or white stripe from the edge of the mouth to the arm. The belly is pale pink with white specks; the male has a dark grey throat. The pupil is horizontal, and the iris is gold. The arms and legs sometimes have horizontal bars. The groin and the backs of the thighs are bright red. Fingers are unwebbed and toes are half-webbed, both without discs. The parotoid glands are large and orange or pale orange-brown.

Breeding Biology

Eggs are laid singly and attached to vegetation under the surface of the water in creek pools and drainage lines. Tadpoles can reach a total length of up to 3.5 cm, and are gold-brown in colour. They often remain at the bottom of water bodies. It is unknown how long they take to develop into frogs. Breeds during summer in the wet season.

Similar Species

Looks very similar to Uperoleia minima and Uperoleia micra and Uperoleia inundata in its distribution, but has a different call to all of these species and is generally smaller than Uperoleia inundata and larger than Uperoleia minima and Uperoleia micra.
