This species is known only from Belitung Island, Indonesia.
Habitat and Ecology
This species is presumed to occur in tropical moist forest, where the adults are likely to be subterranean, and it is also presumably oviparous with terrestrial eggs and aquatic larvae.
It is known only from the holotype, and there have been no recent records, presumably due to a lack of herpetological work within its range.
There has been severe habitat conversion on Belitung Island due to oil palm plantations and opencast tin mining, although it is not known to what extent this is threatening this species. The only remaining forested habitat is on Mt. Tajam (A. Hamidy pers. comm. May 2017).
It does not occur in any protected area.
Further studies are needed to determine whether or not or not it is a valid species (D. Iskandar pers. comm.), along with studies on its population size, distribution, ecology, and threats.
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.
