A new species of scops-owl (Aves, Strigiformes, Strigidae, ) from Príncipe Island (Gulf of Guinea, Africa) and novel insights into the systematic affinities within .

A new species of scops-owl (Aves, Strigiformes, Strigidae, ) is described from Príncipe Island, São Tomé and Príncipe (Gulf of Guinea, Africa). This species was discovered for science in 2016, although suspicions of its occurrence gained traction from 1998, and testimonies from local people suggesting its existence could be traced back to 1928. Morphometrics, plumage colour and pattern, vocalisations, and molecular evidence all support the species status of the scops-owl from Príncipe, which is described here as Phylogenetic analyses suggest that this species descended from the first colonisation of the Gulf of Guinea islands, being sister to the clade including the mainland African Scops-Owl , and the island endemics Sao Tome Scops-Owl and Pemba Scops-Owl .
