Assessment Rationale:

This species is endemic to the Madeiran archipelago, where it is probably present within the laurisilva zone in the steep-sided valleys. Even though it is relatively restricted, it is known from a large number of locations and hence it is probably not threatened, although some sites may be impacted by local habitat disturbance. For example the sites on Madeira may have been impacted by the recent forest fires (August 2010). It is listed as Least Concern (LC).

Geographic Range:

This species is endemic to the Madeiran archipelago. It is mainly found at intermediate elevations on Madeira within the laurisilva zone were it is present at over 14 sites. It is probably present at other sites at similar elevations in these steep-sided valleys.

Population:

There is no data on population trend, but it is presumed to be stable, even if it is present in low density in samples from the leaf-litter in the Laurisilva forests.

Habitat and Ecology

It is mainly found at intermediate elevations on Madeira within the laurisilva zone, where it is on ferns and amongst moss and lichen on the trunks of laurels.

Major Threat(s):

There are no widespread threats to the species which lies on five different islands in two different island groups.

Conservation Actions

There are no conservation actions specific to the species. However, some parts of the range lie in protected areas, so some habitat protection is provided.
