Assessment Rationale:

This large and conspicuous species has not been found living in any recent survey work over the last 40 years. It was last seen prior to 1878, and may well have been extinct over most of the range much earlier than this as it is a common Quaternary fossil over the island (Seddon 2008).

Geographic Range:

This species was endemic to the Madeiran islands, and according to Wollaston (1878) one specimen was collected alive by Moniz in the 19th century on Ilheu de Cima off Porto Santo; otherwise it is present abundant as a Quaternary fossil on Porto Santo (Cameron et al. 2006) and adjacent islet of Ilheu de Baixo; it is now thought to be extinct (Seddon 2008).
