Assessment Rationale:

The species is only present in the northern Teno Mountains on Tenerife where it is known from four locations, but it may be more widespread between the sites as the species is difficult to detect as it lives at low density (Groh, pers. comm., 2010). Habitat disturbance due to the extraction of timber for agriculture use of laurisiliva forest could cause fluctuations in the populations and as such this species is assessed as Vulnerable (VU) B2ab(iii).

Geographic Range:

The species is only present in the northern Teno Mountains on Tenerife in the Canary Islands (Groh et al. 1994), but maybe more widespread between the sites (Groh, pers. comm., 2010) because of presence of habitats of laurisiliva forest, which potentially could be colonised.

Biogeographic Realms:
Paleartic
Presence:
Extant
Origin:
Endemic Canaries
Seasonality:
Resident

Population:

This species is difficult to detect because of low population density. Living animals have only been once detected at one site, so trends cannot be given.

Habitat and Ecology

This species occurs in Laurisilva forest where it is ground-dwelling in leaf-litter and under stones.

Major Threat(s):

This species occurs in Laurisilva forest where it is ground-dwelling in leaf-litter and under stones.

Conservation Actions

The species is only present in the northern Teno Mountains on Tenerife in the Canary Islands where Moliner Gomez et al. (2001) suggested it was sensitive to the alteration of the habitat. Its habitat should be protected.
