This species is endemic to Sri Lanka, where it is known only from the non-specific type locality of "Ceylon" (Manamendra-Arachchi and Pethiyagoda 2005). It is not possible to produce a distribution map for this species because the exact location of the type locality is not known.
Habitat and Ecology
The habitat requirements of this species are not known. It presumably bred by direct development.
It is known only from the lectotype and type series, and has not been recorded since the original description in 1864. Recent, extensive field surveys of the amphibian fauna of Sri Lanka have failed to rediscover this frog and it is now considered to be extinct.
The causes of the species' extinction are not known, but presumably habitat loss was a contributing factor.
It has not been recorded from any protected areas.
Red List Status
Listed as Extinct because it has not been recorded for over 100 years, and extensive searches over the last ten years have failed to locate this species.
Specimens formerly attributed to Philautus temporalis and P. leucorhinus from the Western Ghats are now correctly assigned to P. wynaadensis. P. temporalis and P. leucorhinus are now considered to be endemic species of Sri Lanka (S.D. Biju and K. Manamendra-Arachchi pers. comm.).
