This species is known from southern Thailand and Peninsular Malaysia, below 300 m asl (Taylor 1962, Grandison 1972, Berry 1975).
Habitat and Ecology
It occurs in primary and secondary forests, including open areas near forests, particularly along rivers, as well as along forest edges and in areas of low hills in overgrown rubber plantations. It can be found in pools, ponds and marshes both permanent and seasonal within its range. It is tolerant of selective logging. Breeding choruses of about a dozen animals are regularly encountered (P.P. van Dijk pers. comm.). It breeds in pools (Grandison 1972, Berry 1975).
It ranges from being abundant in certain localities to being uncommon in others.
Certain subpopulations are at risk from ongoing loss of their remaining lowland forest habitat, especially from infrastructure development.
Additional protection in existing protected areas within the species' range is recommended (Khao Luang, Khao Nor Chu Chi, Perlis State Park, Taman Negara) and improving protection for other remaining lowland forests (Belum-Temengor, Ulu Muda, Pasoh). Further research into life history and population size are needed for this species.
