Taxonomy and systematics of the nightshade feeding flea beetles Epitrix and Acallepitrix (Coleoptera: Chrysomelidae: Galerucinae: Alticini) in America north of Mexico

Epitrix is a large genus of flea beetles with over 200 described species worldwide and many more undescribed.  They are associated with solanaceous plants and some species are major pests of crops such as potato, tomato, eggplant, and tobacco.  Acallepitrix is a primarily Neotropical genus of solanaceous feeding flea beetles with a single North American representative which is poorly distinguished from Epitrix.  In this preliminary work I redescribe the 13 species of these genera currently known from America north of Mexico as well as several new country records and numerous undescribed species based on morphology.  A key to species, habitus photos of all species, and distributional data are provided.  Preliminary phylogenic data based on morphological characters are presented.
