Population justification
See Geographic Range text.
This newly-recognised species was known with certainty only from Marianne Island in the Seychelles, although it may also have occurred on Praslin, La Digue, Silhouette Island and Mahé. It became Extinct between 1870 and 1900, probably around 1888, and an expedition in 1940 failed to find it.
Little is known, but Marianne is a small, granitic island with a maximum altitude of 130 m.
The cause of extinction is unknown but may be related to invasive species.
