. Fern sporophagy is reported in species of Cryptophagidae, Mycetophagidae and Anthribidae occurring on the Juan Fernandez Islands, Chile. The following taxa are described and/or discussed: Cryptophagidae: Cryptothelypterus gen.n., with five species: C.obrieni sp.n., C.pteropilosus sp.n., C.selkirki (Bruce) comb.n., C.skottsbergi (Bruce) comb.n., and C.splendens (Bruce) comb.n.; Mycetophagidae: Filicivora gen.n., with one species, F.chilensis (Philippi & Philippi) comb.n.; and Anthribidae: Opisolia lenis Jordan. A key to the species of Cryptothelypterus is provided. Convergent adaptations for fern sporophagy in these groups are discussed, hypotheses are given for the evolution of this habit, and comments are made on wing atrophy.
