Justification: This species is endemic to Piedmont in northwestern Italy. It is rare and known from only two localities. It is assessed as Data Deficient due to the lack of data on its population size, trend and threats. Further research is needed into this species to determine its distribution, population trends and extinction risk. |

Range Description: | This species is endemic to northwestern Italy, where it is known only from its type locality (locus typicus restrictus: Colle San Giovanni, Valle Stura di Lanzo, Province of Torino) and another locality (Colle San Giovanni, Viù, Province of Torino) (Alzona 1971, Riedel 1980, Giusti et al. 1986, Cossignani and Cossignani 1995, Manganelli et al. 1995, Riedel 1998, Manganelli et al. 2000, Welter-Schultes 2012, Bank 2013). | ||||||

Habitat and Ecology: | This species is found in leaf litter of deciduous forests, on non-calcareous soils (Manganelli et al. 2000, Welter-Schultes 2012). |
Systems: | Terrestrial |
Generation Length (years): | 3 |
---|
Use and Trade: | The species is not known to be utilised. |
Major Threat(s): | This species has a very restricted distribution area and is rare, but there is no evidence to affirm that this is due to a recent decline (Manganelli et al. 2000). |
Conservation Actions: | Further research is required to confirm the species distribution, population trends and potential threats, but it would be important to protect the only sites from where the species is known (Manganelli et al. 2000). |
