Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2011
Date Assessed: 2010-09-07

This species is endemic to the provinces of Alicante and Valencia in Spain. It has an extent of occurrence of 1200 km2, an area of occupancy of 500 km2 and is found at 3 locations. The major threats (ongoing and future) facing this species are fires and urban expansion (housing). An additional potential threat comes from increased tourism to caves, therefore tourism in this habitat should be regulated. Due to the small number of locations and plausible future threats to this species it has been assessed as Vulnerable (VU D2). If the level of threats was increasing and the quality of habitat started to decrease significantly, then the species would qualify for a higher threat category.

Use and Trade [top]

Use and Trade: This species is collected for shell specimens.

Threats [top]

Major Threat(s): The main threat to this species is from fires. Other potential threats include quarrying, urban expansion, extension of roads, temperature extremes, drought and collecting of shells.

Conservation Actions [top]

Conservation Actions: The main conservation action required recommended for this species is the protection of its habitat and the known populations. Currently all caves in Valencia are protected and almost all of the subpopulations are found in protected areas (caves or regional parks), so enforcement of associated legislation of these is recommended.  In addition to habitat protection a plan of conservation is considered to be necessary.
