This species is currently known from two localities, Corbett's Gap, and from Hunnasgiriya, in the Knuckles Hills of central Sri Lanka. It has been recorded between 1,100 and 1,245m asl (Meegaskumbura and Manamendra-Arachchi 2005). There is also a recent record from the nearby Bambarella Peak (M. Meegaskumbura pers. comm.).
Habitat and Ecology
It is an arboreal species found in the understorey and forest sub-canopy of closed-canopy cloud forest, but can also be found in areas with cardamom as the understorey. Males are usually seen calling from their perches on leaves around 1-3m above the ground. They are dependent on environments with high relative humidity for reproduction, and are seen in higher densities in marshy habitats (Meegaskumbura and Manamendra-Arachchi 2005). It is presumed to be a direct developer like other species of the genus. Its dependence on high humidity makes it particularly vulnerable to any modification of the habitat resulting in the opening up of the forest canopy.
It occurs in relatively low abundance.
The major threat is clearance of the species' forest habitat due to logging and subsistence agriculture; drought, and the use of agrochemicals in cardamom cultivation, are additional threats.
Bambarella Peak is part of the Knuckles Forest Reserve, but the other localities from which it is known remain unprotected.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000km2, its Area of Occupancy is less than 500km2, it is currently known from only three localities, and there is continuing decline in the extent and quality of its forest habitat.
