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.
