Assessment Information [top]

Red List Category & Criteria: Least Concern (Regional assessment) ver 3.1
Year Published: 2011
Date Assessed: 2010-06-24
Assessor(s): Fehér, Z.
Reviewer(s): Neubert, E., Reischütz, A., Cuttelod, A., Páll-Gergely, B., Triantis, K., Roberts, R., Slapnik, R. & Ward, J.

This species lives within a relatively wide range. There are only 15-20  known subpopulations, but due to the hidden life of the species, this number is probably underestimated. There is no reason to suppose that the area of occupancy (AOO), extent of occurrence (EOO), number of locations, number of subpopulations or the number of mature individuals are declining or extremely fluctuating. Therefore, it is assessed as Least Concern (LC).

This species has also been assessed at the regional level as:
European regional assessment: Least Concern (LC).
Mediterranean regional assessment: Least Concern (LC).

Population [top]


Due to the hidden life of this species, there are no data on population trend, but there is no reason to suppose that the number of subpopulations or the number of mature individuals are declining or extremely fluctuating.

Current Population Trend:Stable

Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:No
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:

This species occurs in the subterranean part of rocky (mostly limestone) habitats.


Continuing decline in area, extent and/or quality of habitat:No

Threats [top]

Major Threat(s):

This species occurs in the subterranean part of rocky (mostly limestone) habitats. It is a potential threat to this species if the rocks are destroyed by quarrying or by other reasons such as leaching from waste disposal sites. However, the total destruction of the whole habitat is not very likely, therefore this threat is mostly hypothetical at present.


Conservation Actions [top]

Conservation Actions:

The species is not protected at a national level in the countries where it occurs and most of the known sites are outside of protected areas.

Due to the large and stable population there are no conservation actions currently required for this species.
