Scientific Name:	Pseudophilautus adspersus
Species Authority:	(Günther, 1872)
Synonym/s:	Ixalus adspersus Günther, 1872 Philautus adspersus Inger In Frost, 1985

Assessment Information [top]

Red List Category & Criteria:	Extinct ver 3.1
Year Published:	2004
Assessor/s:	Kelum Manamendra-Arachchi, Sushil Dutta
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Justification: 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.

Geographic Range [top]

Range Description:	This extinct Sri Lankan species is known only from the non-specific type locality of "Ceylon" (not "Peradeniya" as sometimes stated) and from Nuwara Eliya, a resort town among mountains at 1,700-2,500m asl (Manamendra-Arachchi and Pethiyagoda 2005). Only the site of Nuwara Eliya has been mapped here. Reports of this frog occurring in India (Krishnamurthy and Sakunthala 1993) are believed to be erroneous (S.K. Dutta pers. comm. 2002).
Countries:	Regionally extinct: Sri Lanka

Population [top]

Population:	It is known only from two specimens, and was last collected around 1886. It is now thought to be extinct since recent extensive field surveys of the amphibian fauna of Sri Lanka have failed to rediscover this frog.
