Revision of North American Ypsolopha with new taxa and synonyms Jae-Cheon Sohn Department of Science Education, Gongju National University of Education, Chungnam, Republic of Korea Introduction Ypsolopha is the type genus of Ypsolophidae sensu Kyrki (1990) which is sometimes treated as a distinct group of Plutellidae. Ypsolopha has more than 120 Y. aleutianella Y. angelicella Y. arizonella Y. barberella described species worldwide, with the greatest diversity in North America and East Asia; 34 species have been recorded from the Nearctic (Walsingham, 1881, 1889; Beutenmüller, 1889; Busck, 1903, 1906; Kearfott, 1907; Y. barberella (form flavistrigella) Y. cervella Y. cervella (form subsylvella) Y. cockerella Braun, 1925; Meyrick, 1927; Powell, 1967; Heppner, 1982). However, the taxonomic resolution of Ypsolopha in the North America still remains incomplete. Our revision of the North American Ypsolopha revealed nine new species, six new synonyms and one resurrected Y. delicatella Y. dentella Y. dorsimaculella Y. falciferella species. As a result, we suggest a new estimate of Ypsolopha species diversity in North America to consist of more than 37 species. Y. gerdanella Y. leptaula Y. lyonothymnae Y. nella Ypsolopha Latreille, 1796 Y. querciella Y. rubrella Y. schwarziella Y. senex Laterial view of head of Y. laorum (after Robinson et al., 1994) Y. striatella Y. sublucella Y. undulatella Y. ustella Resting posture of Y. blandella Y. vinterella Y. walsinghamiella 2) New Species of Ypsolopha from North America A total of nine new species have been recognized (eight of them shown here). Male and female of Y. contractella, Wing venation of Y. vittella (modified from Moriuti, 1977) Materials & Methods n. sp. A (from Arizona) n. sp. B (from Texas) n. sp. C (from Texas) n. sp. D (from California) Dried specimens were obtained from the following institutes. BMNH – the Natural History Museum, London, UK MCZ – the Museum of Comparative Zoology, Harvard University, n. sp. E (from Texas) n. sp. F (from Arizona) n. sp. G (from California) n. sp. H (from Arizona) Cambridge, USA MSU – the Mississippi Entomological Museum, Mississippi State 3) Specific topics remaining to be solved in future study University, Starkville, USA. UCB – the Essig Museum of Entomology, University of California, - What would be biological factors underlying three distinctive forms of Y. dentiferella? Berkeley, USA USNM – the U.S. National Museum of Natural History, Washington DC, USA Dissections of the genitalia were prepared following Clarke (1941), except chlorazol black was used for Y. dentiferella Yellow form of canariella auct. Brown form of canariella auct. frustella auct. staining. Terminology follows Klots (1970) for genitalia and Forbes (1948) for wing venation. - How many species are there in Y. oliviella and unipunctella complex? Taxonomy 1) An updated checklist of the previously described North American Ypsolopha A total of 28 species have been recognized in this study. All type specimens of the species Typical form of Y. oliviella Typical form of Y. unipunctella A variant from Arizona except two, Y. dentella and Y. elongata have been examined. All known or new synonyms and revised statuses are shown in the list. Ypsolopha aleutianella (Beutenmuller, 1889) Ypsolopha angelicella (Busck, 1903) = Cerostoma maculatella Busck, 1906, n. syn.
