|Scientific Name:||Belgrandiella austriana|
|Species Authority:||(Radoman, 1975)|
Frauenfeldia lacheineri Kuster, 1853
Graziana austriana Radoman, 1975
|Taxonomic Notes:||This species is one of many small spring-snails that can be most easily identified using anatomical characters of the reproductive system. Originally, this species was found to be living with another spring snail Graziana lacheineri (Gloer 2002).|
|Red List Category & Criteria:||Critically Endangered B1ab(iii)+2ab(iii) ver 3.1|

Belgrandiella austriana has been assessed as Critically Endangered. This species is known from a single site that is threatened by pollution and water extraction. There has been a population decline and it is now considered to be 'rare'. This species is also listed in the Austrian Red List as Critically Endangered (CR). It is therefore considered as Critically Endangered (CR) B1ab(iii)+2ab(iii).
|Range Description:||Belgrandiella austriana is endemic to southeastern Austria, where it is recorded from Andrtiz-Ursprung, north of Graz. This species is only known from the type locality and believed to be restricted to this site.|

The population of this species exists at very low densities compared to the other spring-snails at the same site (one specimen of Belgrandiella austriana to 1,000 of the other spring snail) (P. Reischütz pers. comm. 2009).
|Habitat and Ecology:||This species only exists in one freshwater spring.|
|Major Threat(s):||This species is only known from a single site, where it lives in low abundance compared to the other species found at the site. The spring is not in a protected area; it lies on private land and is therefore vulnerable to disturbance and to pollution from agricultural practices. It is also threatened by introduced species and the lowering of groundwater levels.|
|Conservation Actions:||This species is not protected by law and there are no species specific recovery plans in place. It is suggested that monitoring of this species habitat is conducted, along with research into the species population trends. It is found on the Austrian Red List as Critically Endangered (CR).|
