Brown and Harrison provided detailed critical reviews of the manuscript that were exceptionally useful. Many plant identifications were made by Barbara Ertter, UC Herbarium, which retains the voucher specimens. YFH is especially indebted to John Doyen and Thomas Duncan, University of California, Berkeley, for many helpful comments and suggestions and Christopher Meacham and Brent Mishler for assistance with cladistic analysis. Finally, we are indebted to Gordon Nishida, who prepared the illustrations in electronic format, and provided other computer expertise enabling completion of the final copy. ix Abstract Heliodinidae traditionally have been characterized on the basis of forewing venation, color and scaling, and perch behavior, but none of these attributes defines monophyly. We identify four uniquely derived autapomorphies for the family: (1) M vein of forewing two-branched, presumably with M3 lost; (2) tegumen greatly expanded posteriorly, forming a sclerotized, hollow tube; (3) ventral branches of apophyses anteriores originating from a fused transverse bridge; and (4) pupa with long, stiff dorsal and lateral setae. Phylogenetic relationships among genera and species groups of world Heliodinidae are constructed using parsimony and character compatibility as optimality criteria, with representatives of six other families of Yponomeutoidea as outgroups. Results of the analyses show Heliodines Stainton, as formerly recognized (i.e., all the species with conspicuous red markings on the forewings), to be a polyphyletic assemblage. To accommodate the New World fauna, two old names, Aetole Chambers and Embola Walsingham, have been resurrected from synonymy, and three new genera are described: Neoheliodines Hsu (Type species: Heliodines nyctaginella Gibson, 1914), Heliogemma Hsu (Type species: H. gigantea Hsu), and Euheliodines Hsu (Type species: E. chemsaki Hsu). The South American genus Crembalastis Meyrick is synonymized with Embola. A descriptive taxonomy is provided for North and Central American and Caribbean species formerly assigned to Heliodines; 45 species are treated, 25 of which are described as new: Aetole fulgida (TL: Sinaloa, Mexico), A. prenticei (Calif.), A. eximia (Baja Calif., Mexico), A. insolita (El Salvador), A. cera (Calif.), A. favonia (Calif.), A. inusitata (Baja Calif., Mexico), A. aprica (Texas), A. calciferoides (Veracruz, Mexico); Embola autumnalis (Ariz.), E. cyanozostera (Nevada), E. friedlanderi (San Luis Potosí, Mexico), E. melanotela (Haiti); Euheliodines chemsaki (S. L. P., Mexico), E. jaliscella (Jalisco, Mexico); Heliogemma gigantea (Jalisco, Mexico), H. grandis (Tamaulipas, Mexico), H. preclara (Jalisco, Mexico); Neoheliodines albidentus (Ariz.), N. arizonense
