This species is known only from the type locality, at 1,289-1,320m asl, at Batang Sarasah, Lubuk Selasih, near Solok, West Sumatra, Indonesia. It is likely to have similar habits to Megophrys aceras from the Malay Peninsula, so it could be expected to have a wide distribution in montane forest along Sumatra's west coast.
Habitat and Ecology
One individual was found in primary forest, and the others in secondary forest, indicating that this species has at least a degree of tolerance to habitat degradation. Individuals were found on dead leaves, and on a small log on the bank of a small stream. This species is presumed to breed by larval development in streams.
There is no information available on the population status of this species.
The major threats in this region are logging and deforestation for small-scale agriculture or tea plantations. Not only are these a direct threat through loss of habitat, but habitat degradation through loss of humid shaded leaf-litter is also likely to be a problem. Deforestation and agrochemicals will also reduce the number of clear-flowing unpolluted streams available to the larvae.
This species is not known from any protected areas, but the type locality is only 4km from Kerinci Seblat National Park, in which this species is likely to occur.
