The Howard Springs toadlet (Uperoleia daviesae), also known as the Howard River toadlet, Davies's toadlet or the Darwin sandsheet frog, is a species of small frog that is endemic to Australia. The specific epithet daviesae honours Australian herpetologist Margaret M. Davies.

[edit]

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

[edit]

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

Distribution and habitat

[edit]

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]
