Assessment Rationale:

Scotognapha paivani is endemic to the archipelago of Selvagens, Portugal. This species has a restricted geographic range (the extent of occurrence (EOO) is only 13 km² and the area of occupancy (AOO) is 12 km²). However, it is assessed as Least Concern (LC), since the species range is inside the Selvagens Nature Reserve, which seems to be stable with no signs of loss or known threats. A monitoring of population trends should be conducted to confirm species status.
