Assessment Rationale:

Seddon (2008) suggested that this species is likely to be Least Concern (IUCN version 3.1).  Although this species has a restricted extent of occurrence, it is present at many disturbed sites on the south coast of Madeira, suggesting that it is not susceptible to disruption by human activities and has a wide range within this zone and hence is categorized as Least Concern (LC).

Geographic Range:

This species is endemic to the Madeiran islands where it is considered to be restricted to Madeira (although according to Seddon (2008) reporting records from the literature in the 1860-1880 period, it was apparently recorded by Paiva from Bugio in the Desertas but this record remains unconfirmed). On Madeira, it is mainly present on sites on the south coast from Ponta do Pargo to Canical.
