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 species is an extinct Sri Lankan endemic, known only from the general type locality of "Ceylon [=Sri Lanka]" (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. Specimens previously attributed to this species from India (Krishnamurthi and Shakunthala 1993) are now believed to be a separate taxon (Biju 2001), and specimens reported by Karunaratne (1998) are believed to belong to a different species (K. Manamendra-Arachchi pers. comm.)
