Description

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

Breeding Biology

Eggs are laid singly on vegetation under the surface of the water in temporary ponds, flooded drainage lines, and swamps. Tadpoles can reach a total length of up to 4 cm, and are brown in colour. They often remain at the bottom of water bodies, and take around two months to develop into frogs. Breeds during summer in the wet season.

Similar Species

Looks very similar in its distribution to: Uperoleia lithmoda, which has smaller glands and a different call; to Uperoleia crassa, which is smaller and has a different call; to Uperoleia borealis, which is also smaller with a different call; and to Uperoleia arenicola, Uperoleia minima and Uperoleia micra, all of which again have different calls. The best way to differentiate it from Uperoleia daveisae is by DNA.
