This species has a restricted distribution in south-west Sri Lanka, and has been recorded at elevations of between 150 and 460m asl.
Habitat and Ecology
It is a terrestrial species found in, and around, tropical lowland moist forest. Adults have been recorded from rubber plantations, tea estates, and domestic gardens close to the forest edge only. The breeding habitat is not known.
It is not a common species, and populations may be declining proportionately with a loss in forest habitat.
The main threats to the species are habitat loss, due to selective logging, and agrochemical pollution.
It has been recorded from the Kanneliya Forest Reserve, Gilimale-Eratne Forest Reserve and the Sinharaja World Heritage Site; the continued management of these for biodiversity conservation is important.
