|Scientific Name:||Alzoniella lucensis|
|Species Authority:||(Rolan, 1992)|
Belgrandiella cf. cantabrica (Boeters & Rolán, 1988)
Belgrandiella lucensis (Rolán 1993)
A population of A. lucensis found in the province of La Coruna might result from artificial introduction, located in the distribution area of A.rolani. It differs from other populations with absence of penial pigmentation and rounded bursa copulatrix.
|Red List Category & Criteria:||Least Concern ver 3.1|

Alzoniella lucensis is known from a wide area relative to other species of spring-snail and in different habitats, and hence although many of the habitats are vulnerable to exploitation, the species could be considered as Least Concern. However Verdú & Galante (2009) listed the species as Near Threatened, reflecting that the species has a more restricted range and lives in habitats that are exploited for water (Arconada & Ramos pers. comm. 2010). Given the large number of sites and the area over which the species exists, it could be considered Near Threatened if a high proportion of the sites are currently impacted by threats.
EU27: Least Concern (possibly Near Threatened)
Europe: Least Concern (possibly Near Threatened)
Mediterranean: Least Concern (possibly Near Threatened)
Global Assessment: Least Concern.

|Population:||No data is available on status of populations.|
|Habitat and Ecology:||This species is found in a variety of freshwater habitats including small torrents, brooks, wet rocks near rivers, wet rocks with running water, waterfalls and wet walls.|
|Use and Trade:||This species is not utilised.|
|Major Threat(s):||The major threats to these spring-snail species are changes to the hydrological regime, water quality and vegetation in the streams. Possible sources of threats include agricultural developments adjacent to the streams, as well as canalisation of streams to abstract water, with drastic reduction of remaining water flow (Arconada et al. 2009). Other threats include pollution from agricultural sources.|
