A small species of frog reaching up to 3 cm in body length. It has a dark grey or black back. There is often a bright yellow patch on the head and lower back. The belly has black and white marbling. The pupil is horizontal, and the iris is gold. The tops of the arms at the shoulder and the backs of the thighs are often bright yellow. Fingers and toes are unwebbed, both without discs.
Eggs are laid as one small cluster on land under rocks and logs, and in muddy holes in the ground. The nest is guarded by the male, as it is with other Pseudophryne species. Tadpoles can reach a total length of up to nearly 3 cm, and are dark grey-black in colour. They are released into water bodies after the nest is flooded by rain, and take six to seven months to develop into frogs once released. Breeds during spring to autumn after rain.
Looks similar to Geocrinia victoriana, Pseudophryne bibronii, and Pseudophryne semimarmorata in its distribution, but these species lack bright yellow on the tops of the arms at the shoulder, except for Pseudophryne bibronii, which generally has a duller yellow.
