Assessor(s): Prie, V.
Reviewer(s): Gargominy, O., Seddon, M.B. & Cuttelod, A.
In 1996 this species was listed as Vulnerable (Vu D2), based on the past information on restricted distribution, however recent surveys by Prie (pers. comm., 2009) shows the species is now known to have a wider range in the subterranean habitats that are difficult to sample, and as such the listing is revised to Least Concern.
1996 Vulnerable
1994 Indeterminate (Groombridge 1994)
1990 Indeterminate (IUCN 1990)

Threats [top]

Major Threat(s): As this species is widespread, it is only locally threatened. 

Species that live in subterranean habitats  are vulnerable to water pollution from domestic (sewage and run-off) or agricultural (nutrient loads, herbicide and pesticides) sources.  The species is also vulnerable to habitat degradation as the result of over-abstraction of water from the aquifer.
