Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA MOLLUSCA GASTROPODA STYLOMMATOPHORA HYGROMIIDAE

Scientific Name: Canariella pthonera
Species Authority: Mabille, 1883

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2013
Date Assessed: 2010-09-30
Assessor(s): Groh, K. & Alonso, R.
Reviewer(s): Neubert, E. & Cuttelod, A.
Justification:
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).
History:
1996 Lower Risk/conservation dependent (Baillie and Groombridge 1996)
1994 Vulnerable (Groombridge 1994)
1990 Vulnerable (IUCN 1990)

Geographic Range [top]

Range Description: 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.
Countries:
Native:
Spain (Canary Is.)

Population [top]

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
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species occurs in Laurisilva forest where it is ground-dwelling in leaf-litter and under stones.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is not used.

Threats [top]

Major Threat(s): The main threat to this species is the disturbance due to the extraction of timber for agriculture use of laurisiliva forest which could cause fluctuations in the populations.

Conservation Actions [top]

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.
