Assessment Rationale:

This species is endemic to the north-eastern coast of Tenerife, where it is very localized to about 7 locations which are scattered because of urban development on the coast, so the species range has become fragmented. It is impacted by multiple threats in the region: urban developments, road construction and quarrying. The two more localised threats of quarrying and road construction impact severely the species with lost populations, but within smaller more defined areas.

The species has been assessed as Endangered (EN B2ab(iii)).

Geographic Range:

This species is endemic to the north-eastern coast of Tenerife, where it is very localised to about 7 locations  (9 sites) which are quite scattered localities because of urban development on the coast, so the species range has become fragmented (Ibanez et al. 1987).

Habitat and Ecology

This species occurs on lowland vegetation on canary islands and within malpais, volcanic tubes.

Major Threat(s):

The major threats includes habitat loss through urbanisation, road construction, tourist recreation areas and quarrying of the habitat for roadstone.

Conservation Actions

The habitat of this species should be protected.
