Spiders (Arachnida, Araneae) of the site of community importance and special area of conservation "Alpi Marittime" (NW Italy)

and Special Area of Conservation IT1160056 “Alpi Marittime” (NW Italy). The checklist is based on literature records and unpublished material collected from 2007 to 2013 within the first European All Taxa Biodiversity Inventory coordinated by the European Distributed Institute of Taxonomy (EDIT). The examination of the literature provided a list of 113 species recorded for the study area between 1890 and 2013, scattered in 35 publications. During the fieldwork, we collected 4390 specimens at 79 different localities through 264 sampling events. The original data provided here raise the total number of species known for the study area to 295, grouped in 147 genera and 31 families. We recorded a remarkable percentage (9%) of endemic species, including rare endemic elements poorly known in literature, such as Vesubia jugorum,Troglohyphantes konradi, Nesticus morisii and Turinyphia clairi. Thirty‐eight species are new records for the regional fauna and four species are recorded for the first time in Italy.
