 The Annobón paradise flycatcher was previously classified with the Old World flycatcher family Muscicapidae, but the paradise flycatchers, monarch flycatchers, and allies are now placed in a separate family, Monarchidae, which has most of its members in Australasia and tropical southern Asia.Within its genus, the Annobón paradise flycatcher was split from the red-bellied paradise flycatcher in 2009 by the IOC.Some other authorities continue to treat the Annobón paradise flycatcher as a subspecies of the red-bellied paradise flycatcher ("T. rufiventer smithii").
