Description

A medium-sized species of frog reaching up to nearly 5 cm in body length. It has a dark brown back, with pale brown-yellow or orange-yellow spots and squiggle-shaped markings. The lower half of the side is pinkish-white, sometimes with pale brown-yellow spots. The belly is white. The pupil is vertical, and the iris is silver-grey. Fingers are unwebbed and toes are half-webbed, both without discs. There is also a black metatarsal tubercle on the bottom of each foot: this is a shovel-shaped lump used for burrowing.

Breeding Biology

Eggs are unknown, but are likely to be similar to other Neobatrachus species and laid under the surface of the water in flooded grassland, roadside ditches, and claypans. Tadpoles are unknown, but likely to be similar to other co-occurring Neobatrachus species in colour, habit, and development time. It is unknown how long they take to develop into frogs. Breeds during summer to autumn after heavy rain.

Similar Species

Looks similar to Neobatrachus pelobatoides, Neobatrachus sutor, and Neobatrachus wilsmorei in its distribution, but has a different back colour to Neobatrachus pelobatoides and Neobatrachus sutor, and a different back pattern to Neobatrachus wilsmorei.
