Habitat and Ecology
A terrestrial species associated with wet leaf-litter, rocks and other ground cover, close to streams in tropical wet montane forest, its breeding biology has not been recorded, but it presumably takes place in water, probably in streams, by larval development.
Little is known about the population status of this species, but it is not common.
Habitat loss (small-scale agriculture) and human disturbance (local tourism) are the primary threats to this species.
It has been recorded from several protected areas, including the Kitulgala Forest Reserve, Messana Forest Reserve and the Sinharaja World Heritage Site.
