Similar Species

Looks similar to Crinia signifera, Pseudophryne dendyi, and Pseudophryne semimarmorata in its distribution, but Crinia signifera lacks bright colours and has horizontal bars on the legs, whilePseudophryne dendyi has brighter yellow on the tops of the arms at the shoulder, and Pseudophryne semimarmorata has a different belly colour and distinct black spots on the back. Also looks similar to Geocrinia laevis, Geocrinia victoriana,Pseudophryne coriacea, and Pseudophryne major in its distribution, but has a different back colour.


Found in most of VIC, the highlands of the ACT, southeast SA, far southeast QLD, and along the coast and ranges of NSW.

Breeding Biology

Eggs are laid as one small cluster on land under moist leaf litter, rocks, logs, and Sphagnum moss. The nest is guarded by the male, as it is with other Pseudophryne species. Tadpoles can reach a total length of up to 3.5 cm, and are dark grey or brown in colour, with black mottling. They are released into water bodies after the nest is flooded by rain, and take four to six months to develop into frogs once released. Breeds during any time of the year after rain.
