Specimens currently assigned to this species have been collected in Sri Lanka and the Western Ghats of India. It has an altitudinal range of 60-1,830m asl in Sri Lanka and 200-1,800m asl in the Western Ghats.
Habitat and Ecology
It is a largely terrestrial species (although males can be seen in low vegetation) associated with shaded hill streams and riparian vegetation in semi-evergreen moist tropical forest. It is not found in modified (agricultural) habitats. Adults are often encountered on wet boulders in streams, and breeding takes place in these streams.
It is locally abundant.
The main threats to this species are the conversion of forested land for agricultural use (for tea, cardamom, and rubber plantations), subsistence harvesting of wood and timber, the development of mining and roads (in India), agrochemical pollution and (again in India) the construction of dams.
It has been recorded from many protected areas in Sri Lanka, and in India (where it is protected by national legislation) it has been recorded from Konya Wild Life Sanctuary in Maharashtra, Kudremukh National Park in Karnataka, and Kalakad-Mundanthurai Tiger Reserve in Tamil Nadu. It is included as part of ongoing studies by Biju (1998 and onwards) and Addoor (1992 and onwards).
Red List Status
Near Threatened (NT)
Listed as Near Threatened because its Extent of Occurrence is probably not much greater than 20,000 km2, and the extent and quality of its habitat are probably declining, thus making the species close to qualifying for Vulnerable.
The population in the Western Ghats assigned to Hylarana temporalis probably belongs to an undescribed species (S.D. Biju and K. Manamendra-Arachchi pers. comm.). Pending taxonomic revision, H. temporalis is treated here as a single species.
