Assessment Rationale:

This species is endemic to the Madeira Archipelago (Portugal), where it ioccurs in Madeira Island and Desertas (Chão, Deserta Grande and Bugio). According to Seddon (2008), there are four confirmed locations of the species, however given the difficulty in separating this taxon from A. tornatellina, the present species might be under-recorded, and requires further distribution research. Since it is present in four different islands, there are probably more than four locations and no threats have been reported, the species is assessed as Least Concern (LC).

Geographic Range:

This species is endemic to the Madeira Archipelago (Portugal), where it ioccurs in Madeira Island and Desertas (Chão, Deserta Grande and Bugio) (Teixeira and Cameron pers. comm. 2016). Cameron et al. (1996) recorded the species alive on Chão and Deserta Grande and as a fossil on Bugio. Seddon (2008) stated that the species is restricted to four localities on Madeira but is probably underrecorded due to taxonomic difficulties in separating this taxon from A. tornatellina. The identification of the Madeira subpopulations requires further investigations.

There are no population abundance data for this species, although there have been regular records over the last 30 years.

Habitat and Ecology

The species can be found under leaves and stones (on Madeira) or in debris on ledges on rock faces (on the Desertas Islands). In Madeira, this species was found on grasslands (Ponta de São Lourenço) and in mild coastal sites between Calheta and Porto Moniz (southwest).

Conservation Actions

This species is protected under Natura 2000 SAC "Pico Branco", "Ponta de São Lourenço" and "Ilhas Desertas" and also on SCI "Paul do Mar - Jardim do Mar", which covers a huge part of its range. All the SAC have management and conservation plans in place and they all have established periodic species and habitat monitoring schemes.
