Uperoleia marmorata commonly known as the marbled toadlet, is only known by the holotype collected in the Kimberley region of Western Australia by Gray in 1841.

Gray describe the frog as "…black and green marbled, leaving a triangular greenish spot on its forehead, beneath lead colour".

Due to lack of records on this species habitat and behavioural characteristics have been difficult to assess.

The frog is likely to breed in permanent and semi-permanent still water bodies in the Kimberly region.

This species was once thought to be widespread across eastern New South Wales, but due to the similarity of frogs within the genus Uperoleia it was most likely confused with smooth toadlet.
