This species is known from a valley inland from Cabo Girao and is threatened by habitat loss due to the development of tourist accommodation. Seddon (2008) proposed the listing should be as Vulnerable (VU) D2, based on restricted area and possible threats of habitat decline due to development of land. This listing was confirmed during evaluation of this assessment (November, 2010).
This species is endemic to Madeira where it is restricted from Cabo Girao inland within this valley (Seddon 2008).
This is a large helicid which is easily collected and is frequent in samples taken within the right area (Seddon 2008).
The species is found in grassland, open scrubby vegetation and rocky slopes (Seddon 2008).
The habitat has been subject to changing land-use practice as a result of hotel developments and increasing urbanisation and as such the quality of the habitat has declined (Seddon 2008).
The habitat does not lie within a protected area and has been subject to changing land-use practice for the last 50 years as result of hotel developments and increasing urbanisation (Seddon 2008). Habitat monitoring and population monitoring are required to establish the species limits and check the long-term trends for the species.
