〔ange Description This species is endemic to the central hills of Sri Lanka where it has been recorded at elevations of 1,830-2,135m asl. Habitat and Ecology It is generally restricted to montane tropical moist forest habitats. Adults can be found in leaf-litter (and are at least partially fossorial), under stones and other ground cover, beneath bark, on the trunks of trees, and in the canopy. Breeding is thought to take place by larval development, like other members of its genus, but it is not known whether or not it requires water for breeding. Population It is a rare species. Population Trend Decreasing Major Threats The principal cause of decline appears to be habitat loss through the conversion of forests to cultivated land (tea plantations), logging with subsequent replanting of plantation forests (in Pattipola) and droughts and fire (especially in Horton Plains National Park). Die-back of mature trees in Horton Plains National Park and Hakgala Strict Nature Reserve is also a key threat to the species (although the causes of this die-back are not known). Conservation Actions Besides Horton Plains National Park and Hakgala Strict Nature Reserve, it is also recorded from Agra-Bopats Forest Reserve and Pattipola Forest Reserve. Further research is needed to investigate the breeding biology of this species, and also to understand the reasons for the die-back of mature trees in some of its key protected habitats.
