Sardohoratia islamioides is endemic to Italy, where it is restricted to western Sardinia. It is known from 3 localities, where it is only present in the interstitial waters, and as such is considered to be very vulnerable to disturbance, either from pollution of the water, or from disturbance of the springs (Manganelli et al. 1998).  As one location has possibly been lost due to modification for water abstraction, the species is listed as Endangered (EN) B2ab(ii,iii,iv).

This species is endemic to Italy, where it is restricted to western Sardinia. The type locality is the 'Plentiful karstic spring Su Cologne, at San Giovanni, 100m ASL (UTM 32 T NK4260). Also known from a spring on right bank of Cedrino River, S. Leonardo (3km upstream of Orosei, UTM 32 T NK5771) and Spring San Giuseppe, Siniscola (UTM 32 T NK5790) at 55m ASL (Manganelli et al, 1998). The possible loss at the type locality was noted by Manganelli et al. (1998).

This species is restricted to a small area, so population numbers are presumably relatively low and the loss of one sub-population suggests a decreasing trend.

This species is restricted to interstitial waters of a spring within a karstic region (Manganelli et al. 1998). It is a strict stygobiont (i.e. species generally restricted to subterranean groundwater habitats and characterized morphologically by loss or severe reduction of eyes and pigment). Like most spring-snails, the species feeds using a radula, scraping rock surfaces.

The species is threatened by its restricted range (Ruffo and Stoch 2006). Since it inhabits groundwaters, the species could be affected by anthropogenic groundwater abstraction and/or pollution (Manganelli et al. 2000). In 1998, Manganelli noted that this species has not been found living at the spring at Su Cologne since it was exploited and the bottom surface of the spring cemented over.

This species is not known to be traded.

No specific conservation measures are known. It is not known whether the species occurs in any protected areas.  The species was considered Near Threatened in the Italian Red List (Manganelli et al., 2000).  The species requires a programme of habitat monitoring and survey work to establish population trends at the last two known sites, as well as information about potentially damaging actions.
