This species is endemic to a small part of the Central Hill Country of Sri Lanka, and has been recorded from Agra Bopath (at 1,555m asl) and Ambewela (at 1,830m asl) (Manamendra-Arachchi and Pethiyagoda 2005). It might occur more widely than current records suggest.
Habitat and Ecology
It occurs in both open and closed-canopy vegetation, including cloud forests and adjacent anthropogenic habitats. They have been observed 1-5m above ground, perched on leaves and twigs on shrubs, in the forest understorey. In closed-canopy habitats, it inhabits the top stratum (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 an uncommon species.
The habitat of this species is gradually declining due to encroachment by tea cultivation and human settlements, and it is particularly sensitive to the removal of the humus layer where it lays its eggs. It is probably also threatened by agro-chemicals.
It is not found in any protected areas, making the protection of its forest habitat an urgent priority.
