|The area in which the holotype was found of the Marbled Toadlet.|
Gray describe the frog as "…black and green marbled, leaving a triangular greenish spot on its forehead, beneath lead colour". This species is likely to have other features similar to other Uperoleia species such as: red-orange patches in the groin and behind the knees, tubercles and large parotoid glands as well as a granular belly. The frog is likely be to about 30mm in length.
This frog most likely resembles the Mjoberg's Toadlet (Uperoleia mjobergi), as they inhabit similar areas it is possible to speculate that the holotype of the Marbled Toadlet was mistake for a Mjoberg's Toadlet.
Ecology and behaviour
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.
