Taxonomic Notes:


Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2011
Date Assessed: 2010-01-28
Assessor(s): Seddon, M.B.
Reviewer(s): Burden, A., Van Damme, D., Arrébola, J. & Fehér, Z.
Justification:

Spiralix affinitatis is newly described species endemic to Spain, where it is only known from two localities. There is no current data on the threats to these sites, and further information is needed on the distribution and population status of this new species, therefore it has been assessed as Data Deficient (DD). However there are general threats to subterranean habitats through water pollution and over-abstraction and if the sites become threatened, then on a precautionary basis the species should be listed as Vulnerable (VU D2).

Threats [top]

Major Threat(s):

It is unknown whether this species is being impacted on by any major threat processes, however subterranean habitats are vulnerable to water pollution from both domestic (sewage and run-off) and agricultural (nutrient loads, herbicide and pesticides) sources. Decline in habitat following falls in the water table levels maybe another threat if the aquifers are overexploited.

Conservation Actions [top]

Conservation Actions:

There are no species-specific conservation measures in place for this species. Further research is recommended to determine the extent of its distribution and to identify any threat processes impacting upon its habitat.
