Interpretive Summary: Moth larvae of the leaf-roller genera Ecdytolopha, Gymnandrosoma, and Pseudogalleria are pest of citrus, macadamia, cocoa, guava, lychee, and several other tropical crops. They are responsible for millions of dollars of damage annually, primarily in South and Central America and the Caribbean. Larvae of these genera frequently are intercepted at U.S. ports-of-entry, either in commercial commodities or, more frequently, in personal baggage. Our lack of understanding of the relationships among the species and the absence of a comprehensive treatment of the larvae inhibit our ability to identify accurately these interceptions and implement appropriate quarantine actions. The genera and species are characterized, and keys and illustrations for accurate identification are presented. This information will be useful to scientists studying the classification of related groups worldwide, to pest managers working on control of pests of citrus, macadamia, and cocoa, and to regulatora personnel in APHIS charged with identifying insects and making quarantine decisions.

Technical Abstract: The New World genera Ecdytolopha Zeller, Gymnandrosoma Dyar, revised status, and Pseudogalleria Ragonot are revised. As currently defined, Ecdytolopha includes ten species: E. insiticiana Zeller, 1875 (type species), ranging from southern California to Florida, and from the East Coast to California; E. mana (Kearfott, 1907) from the southern United States (Alabama to Arizona and Maryland); E. exploramae, new species, from Peru; E. beckeri, new species, from Tamaulipas, Mexico; E. occidentana, new species, from Arizona, USA; E. coloradana, new species, from Colorado and New Mexico, USA; E. sinaloana, new species, from Sinaloa, Mexico; E. leonana, new species, from Nuevo Leon, Mexico; E. holodesma (Walsingham, 1914), new combination, from Morelos, hidalgo, and Distrito Federal, Mexico; and E. ricana, new species, from Costa Rica. Gymnandrosoma includes seven species: G. punctidiscana Dyar, 1904 (type species), revised dstatus, from the eastern and southeastern USA; G. cryptotortana, new species, from Veracruz, Mexico; G. linaresensis, new species, from Nuevo Leon, Mexico; G. trachycerus Forbes, 1931, revised status, from the Caribbean; G. leucothorax, new species, from the Caribbean; G. aurantianum Costa Lima, 1927, revised status, from South Amereica, Central America, and the Caribbean; and G. desotanum Heinrich, 1926, revised status, from Florida, USA. Pseudogalleria is monotypic, with the single species P. inimicella (Zeller, 1872), from eastern USA. Members of these three genera include pests of Citrus, Robinia, Macadamia, Pithecellobium, Theobroma, and Psidium. We present a hypothesis of the phylogenetic relationships among these three New World genera and the Old World genera Cryptophlebia Walsingham and Thaumatotibia Zacker.
