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 to be about 30 mm 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==
