The authors examine relationships within the Chrysoxena group of the tortricid tribe Euliini. They define 54 species among six genera: Chrysoxena Meyrick; Vulpoxena Brown, new genus; Thoridia Brown, new genus; Dorithia Powell; Cuproxena Powell and Brown, new genus; and Bidorpitia Brown, new genus. Using cladistic methods, the authors develop a phylogenetic hypothesis for the genera and species groups of Dorithia and Cuproxena. A systematic treatment of the included species provides appropriate generic assignment for several previously misplaced species and describes many taxa as new.

The authors revise the genus Anopina of the leafroller family, Tortricidae (Lepidoptera). This genus ranges from southern Canada to Costa Rica, with its greatest species richness in the higher elevations of Mexico. The larvae are suspected to be leaf-litter feeders. Sixty-two species are treated, of which forty-nine are described as new to science. The authors provide a hypothesis of phylogenetic relationships of the species, propose a classification, supply a key to species groups based primarily on features of the genitalia, and include illustrations of adults, larvae, and male and female genitalia.
