Description

A small species of frog reaching up to nearly 3 cm in body length. It has a copper-coloured or reddish-grey back, with small black spots or patches. There is a black stripe from the tip of the snout to the groin, below which the side and head are often grey with white and black dots, clearly separated from the back colour. The belly has black and white marbling. The pupil is horizontal, and the iris is gold in the upper half and dark brown in the lower half. The upper surfaces of the arms and legs are red; the undersurfaces are grey or black. Fingers and toes are unwebbed, both without discs.

Breeding Biology

Eggs are laid as one small cluster on land in seepages under moist leaf litter, rocks, logs, and sedges. The nest is guarded by the male, as it is with other Pseudophryne species. Tadpoles can reach a total length of up to 2.5 cm, and are dark brown or light brown-gold in colour. They are released into water bodies after the nest is flooded by rain. It is unknown how long they take to develop into frogs once released. Breeds during spring to autumn after rain.

Similar Species

Looks similar to Pseudophryne bibronii, Pseudophryne coriacea, and Pseudophryne major in its distribution, but Pseudophryne bibronii and Pseudophryne major both lack clearly separated side and back colours, while Pseudophryne coriacea is generally brighter in colour.
