Description

The species grows to about 25 mm in length (SVL). The upper body is grey to grey-brown. The belly is pale pink, speckled white. The throat of the male is dark grey. The fingers are unwebbed; the toes only slightly webbed. The backs of the thighs and groin are red to orange. [3] The call of species is short and raspy. [4]

Behaviour

Breeding takes place during the wet season. Eggs are attached singly to submerged vegetation in shallow pools and flooded grassland. [3]

Distribution and habitat

The species' known range is limited to the vicinity of Howard Springs, some 30 km south-east of the city of Darwin in the tropical Top End of Australia's Northern Territory. [3] There the frogs inhabit sandplain heathland, within the Howard and Elizabeth River catchments, that is inundated during the wet season. [4]

Gurrumul's toadlet is a species of frog in the family Myobatrachidae. It is endemic to the Wessel Islands of the Northern Territory, Australia. It is only known from 3 specimens collected in 1993 and was found to be a distinct species via genetic analysis, and thus little is known about its diagnostic features from other Uperoleia species. It can be distinguished from the stonemason's toadlet by its rounded inguinal glands, but appears physically identical to the flood plain toadlet.
