This species is only known from the holotype from Weh Island, at the northern tip of Sumatra, in Indonesia.
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.
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.
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.
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.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing doubts as to its taxonomic validity as well as absence of recent information on its extent of occurrence, status and ecological requirements.
This species might not be taxonomically valid.
