[3] Whether it is distinct from Aubria subsigillata has been debated, but at present it is treated as a valid species.

[1][2][3][4] Adult males typically measure 63–79 mm (2.5–3.1 in) in snout–vent length; females are larger.

Both sexes have conspicuous yellow-brown femoral glands close to the knee.

Breeding takes places in standing water - pools, swamps, and marshes.
