Play call

The Rough-sided Frog occurs in lowland areas including primary and secondary rainforest, freshwater swamp forest and disturbed areas.

The species is most often encountered at the margins of small streams or pools in flooded forest areas. Tadpoles of the species, however, appear only to have been found in shallow forest pools.

This frog is moderately large, often with attractively patterned skin comprising dark brown blotches on a creamy background. The underside is pale. A key identifying feature is the large, brown external ear drum in the center of which is a creamy or buff spot. This feature helps to distinguish the Rough-sided Frog from the similar Golden-eared Rough-sided Frog Pulchrana baramica in which the ear-drum and central spot are of different colour, generally light brown or yellow-orange.

Though there may be variance in the dorsal colours and patterning, most specimens appear to possess dark lips distinctly patterned with bright cream or white spots.

The Rough-sided Frog ranges from southern Thailand, and parts of Indochina through Peninsular Malaysia to Sumatra and Borneo. It is absent in Singapore.
