This species is known from just two locations in south-western Sri Lanka: Morningside (at 1,060m asl), near Rakwana in the Sinharaja area; and Pituwala (at 60m asl) (Manamendra-Arachchi and Pethiyagoda 2005).
Habitat and Ecology
It inhabits closed-canopy forests and cardamom plantations within forests, usually close to water. Adult males have been observed at night, vocalizing while perched on low shrubs, 0.3-2m above ground (Manamendra-Arachchi and Pethiyagoda 2005). It breeds by direct development, and is not dependent upon water. The female excavates a deep hole in the forest floor where the eggs are then deposited.
It is a rare species.
The major threat is the loss of habitat due to firewood collection, the encroachment of tea cultivation, and expanding human settlements; agro-chemical pollution is an additional threat.
Specimens have been collected from the Sinharaja World Heritage Site (the largest remnant of Sri Lanka's forests), and forest reserves bordering the eastern margin of the World Heritage Site.
