This species is known from Nakhon Sri Thammarat in Thailand (Taylor 1962) southwards through most of Malaysia Peninsular (as Megophrys montana; Berry 1975) to Melaka, and from Sumatra (Indonesia). It occurs from lowlands (at about 150 m asl) to montane forests (over 1,500 m asl) (Dring 1979).
Habitat and Ecology
This species inhabits closed-canopy evergreen forests. Tadpoles develop in forest streams.
There are no published data and collected series are generally modest (Grandison 1972, Dring 1979), corresponding to the 'occasional' encounter rates at most localities; although it can be locally abundant (P.P. van Dijk, J. Sukumaran, D. Sharma, J. Tang, Y. Norsham, D. Iskandar and Mumpuni pers. comm.).
This species appears sufficiently widespread and adaptable to be threatened by nothing but widespread systemic habitat degradation, pollution or epidemic disease.
Provided existing protected areas in Peninsular Thailand, Malaysia and Sumatra remain intact and free from disease impacts, no additional conservation actions seem necessary for this species.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population and because it is unlikely to be declining fast enough to qualify for listing in a threatened category.
There are many confusing variants, and erroneous attributions of Xenophrys aceras to Megophrys monticola. Research is needed to confirm whether or not the animals from the Malay Peninsula and Sumatra belong to the same species.
