Description

A medium-sized species of frog reaching up to nearly 5.5 cm in body length. It has a brown or brown-yellow back, with darker brown patches. The belly is white. The pupil is nearly round and the iris is gold. Fingers and toes are slightly webbed, both without discs. The head is distinctly flattened between the eyes.

Breeding Biology

Eggs are laid as a foamy mass on the surface of temporary ponds in flooded grassland, swamps, and billabongs. Tadpoles can reach a total length of up to 10.5 cm and are gold in colour, or grey with evenly spaced brown spots. They often remain at the bottom or mid-depths of water bodies, and may take around two months to develop into frogs. Breeds during summer in the wet season.

Similar Species

Looks similar to Limnodynastes convexiusculus and Limnodynastes lignarius in its distribution, but has a different call and a more flattened head shape compared to both species. It lacks the distinct and large tympanum of Limnodynastes lignarius.
