This species is only known from Haycock Hill (Hiniduma) Forest Reserve (06° 20'N; 80° 18'E) in south-western Sri Lanka, at 660m asl (Manamendra-Arachchi and Pethiyagoda 2005). It seems to be restricted to the type locality.
Habitat and Ecology
The type specimen was found in closed-canopy forest on a wet rock. It presumably breeds by direct development and is not dependent on water.
It is known only from the type specimen and is believed to be a very rare species.
The major threat to this species is habitat loss due to the encroachment of tea plantations. It is probably also affected by agro-chemicals.
It occurs in Haycock Hill-Hiniduma Forest Reserve; however, this reserve is in need of better management to ensure the persistence of this species.
