This species is known from a single specimen from Haycock Hill (Hiniduma) Forest Reserve (06° 20' N; 80° 18' E), at 560m asl, in south-western Sri Lanka (Manamendra-Arachchi and Pethiyagoda 2005). It seems to be restricted to the type locality.
Habitat and Ecology
The type specimen was collected from a low (50cm above the ground) branch on the border of forest, beside a tea garden. It presumably breeds by direct development and it is not dependent upon water.
This species is known only from the holotype, and is presumed to be very rare.
The major threat to this species is habitat loss and degradation due to the expansion of smallholder farming, in particular tea plantations. It is also potentially affected by pollution from agricultural chemicals and run-off.
It occurs in Haycock Hill (Hiniduma) Forest Reserve; however, this reserve requires better management to ensure the persistence of this species. Further survey work is needed to determine the precise population status of this species.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2 and its Area of Occupancy is less than 500 km2, all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat in southwestern Sri Lanka.
