Scientific Name: Spiralix vitrea (Draparnaud, 1801)
Spiralix lineolata (Coutagne, 1882)
Taxonomic Notes: The type locality for this species is unknown, so it is uncertain what the original distribution could be and Prie (pers. comm., 2009) suggests that there maybe more than one species with the range currently mapped for this species.

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2010
Date Assessed: 2009-11-10
Assessor(s): Prié, V.
Reviewer(s): Cuttelod, A., Gargominy, O. & Seddon, M.B.
The distribution range of this species is unclear, due to divergent opinions on the taxonomic status of some subpopulations (in particular in Drome and Ardeche). If the whole range is considered, the species would be classified as Least Concern. However, based on  a precautionary approach, and taking into consideration the core distribution range, it is assessed as Near Threatened; the species meets the threshold for VU B2b(iii).

Geographic Range [top]

Range Description:Spiralix vitrea is endemic to France where it is recorded from much of the Rhone valley: Departments of Ain, Isère, Rhône, Drôme and Ardèche. It is widespread in the region, however, the records from the subpopulations the area of Drôme and Ardèche are uncertain in terms of their taxonomic status.

Threats [top]

Major Threat(s): Subterranean habitats are vulnerable to water pollution from domestic (sewage and run-off) or agricultural (nutrient loads, herbicide and pesticides) sources. Overexploitation of the aquifers may lead to reduction in the water-levels, leading to a degradation of the habitat quality.

Conservation Actions [top]

Conservation Actions: This is a nationally protected species in France. More research on the taxonomy and the distribution range is needed.
