This species is known from southern Peninsular Malaysia (Berry, 1975), Singapore (Lim and Lim, 1992; Leong, 2000) and Borneo. It probably occurs more widely than current records suggest, especially in areas between known sites. It is found at elevations below 300m asl.
Habitat and Ecology
It inhabits lowland rainforest, including regenerating forest. Adults and juveniles range widely in swampy forest. Breeding takes place in small, slowly flowing streams. Tadpoles live in slow-flowing sections of forest streams.
In Malaysia and Singapore the species is common, but nothing is known about its' abundance in Borneo.
Lowland forest clearance is the main threat to this species.
It occurs in a number of protected areas in mainland Southeast Asia, but not in Borneo. Preservation of lowland forest is the main conservation measure required for this species.
