Abstract.-The new genus Furnariphilus is described to include three new species from Peruvian hosts within the passerine family Fumariidae, subfamily Fumariinae: F. pagei, the type species of the genus, from Furnarius leucopus Swainson; F. griffithsi from Sclerurus mexican us Sclater; and F. parkeri from Sclerurus caudacutus (Vieillot).
