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.
