This species is known from two locations in Slovenia. The quality of water is important for this species, as it clings to rocks in fast flowing waters, and hence is vulnerable to pollution events that might impact the groundwaters flowing through the habitats of this species, consequently it is listed as Vulnerable (VU D2), although it may qualify for a higher threat level if the severity of threats increase.
|Range Description:||This species is endemic to Slovenia, where it is found in the River Krka. The sources of the river Krka are fed by water that flows underground from the broad karst hinterland of the Grosuplje basin. There is a recent record from Italy, believed to be this species (de Mattia et al. 2009, Museum of Natural History of Trieste).

|Population:||There are no data on population decline levels.|
|Habitat and Ecology:||This species clings to rocks within fast flowing water in caves.|
It is unknown whether this species is being impacted on by any major threat processes, however subterranean habitats where it lives are vulnerable to water pollution from domestic (sewage and run-off) and agricultural (nutrient loads, herbicides and pesticides) sources. Seasonal droughts impacting water levels in the river maybe become more frequent.
|Conservation Actions:||Acroloxus tetensi was listed as Rare in the Slovenian List of Threatened Species, which Slapnik (pers. comm 2010) suggested equated to Vulnerable (VU D2). Conservation actions include monitoring changes in habitat at known sites, as the monitoring data will provide a proxy for decline of the species, as well as the other freshwater molluscs found at theses sites. Confirmation of the presence of this species in Italy will increase the number of known sites, which may change the conservation assessment.|
