Kelum Manamendra-Arachchi, Sushil Dutta |
| Reviewer/s: |

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).
