Abstract. The new genus Funiariphilus is described to include three new species
from Peruvian hosts within the passerine family Furnariidae, subfamily Furnariinae: F.
pagei, the type species ofthe genus, from Furnariiis leucopus Swainson; F. griffithsi from
Sclerurus mexicanus Sclater; and F. parkeri from Sclerurus caudacutus (Vieillot).
