Population [top]

Population: Its population status is unknown, although it is not certain that the species still survives as Weh Island is now heavily degraded and there is practically no forest left.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: No information is available on its habitat and ecology, although it is likely to be a lowland forest species that presumably breeds in water by larval development, though this has not been confirmed.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): There is no direct information known regarding threats to this species, although clearly forest destruction might well have been a serious threat as there is practically no forest habitat remaining on Weh Island.

Conservation Actions [top]

Conservation Actions: It is not known to occur in any protected areas. An assessment of this species is urgently needed to determine whether or not it is taxonomically valid (Iskandar pers. comm.), and the type specimen should be examined as part of this process. A survey is also needed to determine whether or not this species in fact still survives on Weh Island.
