This species is endemic to the Peak Wilderness and the Central Hill Country of south-western Sri Lanka, and has been recorded from 810-1,370m asl. It is currently known from only two sites, but is likely to occur more widely than current records suggest (Manamendra-Arachchi and Pethiyagoda 2005).
Habitat and Ecology
It is terrestrial, and has been observed in closed-canopy habitats, both in disturbed and undisturbed forests. Adults are strictly nocturnal; males have been observed perching on branches of low shrubs 20-50cm above ground (Manamendra-Arachchi and Pethiyagoda 2005). It breeds by direct development, and is not dependent on water. The female excavates a deep hole in the forest floor where the eggs are then deposited.
It is a rare species.
There is some encroachment of the forest habitat of this species, mainly for tea cultivation and firewood collection, and it is potentially at risk from agro-chemicals. The area is also subject to disturbance by visiting pilgrims.
It is found in the Peak Wilderness Sanctuary.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, and its Area of Occupancy is less than 500 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in the Central Hill Country of Sri Lanka.
