This species is known only from the type locality at Morningside, in south-western Sri Lanka (Manamendra-Arachchi and Pethiyagoda 2005). It was recorded at an elevation of 1,270 m asl. It is probably restricted to this area, which is comprised of a single large forest remnant embedded in a deforested matrix. Its extent of occurrence (EOO) and area of occupancy (AOO) are estimated to be 2 km
Habitat and Ecology
The type specimen was collected from a branch about two metres above ground in a cardamom plantation surrounded by forest. It breeds by direct development and is not dependent on water.
It is known only from the holotype and it is believed to be a very rare species.
It is threatened by habitat loss due to agricultural encroachment (especially for tea and cardamom cultivation), fires, illegal gemstone mining and logging, and human settlement (Surasinghe and Jayaratne 2006). It is also at risk from agrochemical pollution.
