It is a relatively large species for its genus reaching about 40 mm in length, making it the largest Australian "toadlet".
Males make a grating "ark" call after rain from hidden localities, during most of the year.
Eggs are laid in moist situations and hatch after heavy rain floods the nest site where tadpoles continue their development in temporary to semi permanent water.
This species is similar to the Bibron's toadlet (Pseudophryne bibronii) from which it can be distinguished by having more red on the back, pointed snout and blue-grey flanks.
copper-backed brood frog (Pseudophryne raveni) the red-backed toadlet (Pseudophryne coriacea) are also similar to this species, however they can be distinguished by a larger amount of red or copper on the back and a white, not yellow arm patch.
