Zoosystema 48 (6): 139-195, DOI: 10.5252/zoosystema2026v48a6 ABSTRACT We present the inventory of the spiders (Arachnida, Araneae) inhabiting the Orsiera Rocciavrè Natural Park and the Foresto Ravine Natural Reserve (NW Italy).

This work combines data from literature sources, unpublished material, and new samplings conducted between 2018 and 2019 as part of the “Biodiversity Monitoring Project”, supplemented by verified iNaturalist observations. In total, we report 212 species belonging to 128 genera and 32 families, including 12 new records for Piemonte. Linyphiidae Blackwall, 1859 and Gnaphosidae Banks, 1892 emerged as the most represented families, consistently with other similar Alpine parks.
