Species conservation profile of the stenoendemic cave spider Pimoa delphinica (Araneae, Pimoidae) from the Varaita valley (NW-Italy)

Pimoa delphinica Mammola, Hormiga & lsaia, 2016 is a troglophile araneoid spider endemic of the high Varaita valley (Western Alps, Province of Cuneo, NW Italy). In spite of relatively intense field research and examination of museum collections, the species is restricted to ten localities, thus showing a reduced extent of occurrence (EOO; 26 km(2)) and area of occupancy (AOO; 12 km(2)). Although the habitat and the subpopulations of P. delphinica are not currently threatened, the species is potentially exposed due to its extremely narrow geographic distribution range, subdivision in subpopulations and low dispersal capacity.
