Assessment Rationale:

This species is assessed as Least Concern (LC). It has a restricted range, however, it is known from at least 40 localities, hence does not meet the requirements for Vulnerable B2. It should be reviewed on a regular basis as the habitat may be susceptible to decline in quality with changing rainfall patterns, as the species require high humidity in the forests.

Geographic Range:

This species is endemic to Madeiran islands, where it is known living on Madeira only; it has been recorded as a Quaternary fossil on Porto Santo (Groh and Hemmen 1986). It is known at over 30 sites scattered over the island.

Habitat and Ecology

This is one of the larger of the MadeiranĀ Plutonia, found in Laurisilva forests, on theĀ  ground on leaves, mosses and trunks of trees.

Major Threat(s):

The habitat quality is not declining at present throughout these regions, although there are localised decline due to changing forest type, outside the protected areas.

Conservation Actions

There are no conservation actions for this species. Proposed conservation actions would include further surveys to determine whether the species is till stable, and a habitat management plan will be required for the areas under fire damage which includes this species as the species still has a restricted range.
