This species is known from southern Thailand (Yala Province) (Taylor 1962), throughout Peninsular Malaysia (Berry 1975, Dring 1979), Tioman Island, Singapore (Lim and Lim 1992, Leong 2000), Sumatra, Bintan, all parts of Borneo and the Natuna Islands. It occurs up to 1,000 m asl.
Habitat and Ecology
It inhabits intact lowland and submontane rainforest, generally in the vicinity of forest streams. Adults are terrestrial in habits, but tadpoles live in clear forest streams (Dring 1979).
It is regularly encountered and its characteristic call is frequently heard in suitable habitat. It is uncommon in Singapore (Lim and Lim 1992).
Loss and fragmentation of the species' habitat are the major threats. Local populations might become exposed to the hazards of stochastic events. The species is harvested for the national and international pet trade, which might affect local populations.
This species occurs in most protected areas of Peninsular Malaysia (Kiew 1987) and Singapore (Lim and Lim 1992). In Borneo and Sumatra the expansion of effective preservation of lowland forests linked by forested corridors is essential. It has been bred in captivity occasionally by zoos (Frankfurt/Main, Germany) and private hobbyists (Schmidt 1976, Pfeuffer 1989).
Red List Status
Least Concern (LC)
This species is generally recognized as being distinct from Megophrys montana (e.g., Taylor 1962; Inger and Stuebing 1997; Manthey and Grossmann 1997), although other authors have treated it as a subspecies of M. montana (e.g., Grandison 1972; Dring 1979).
