Interpretive Summary: Fruit flies include some of the most important pests of fruits and vegetables, annually causing billions of dollars in losses worldwide. Other species are beneficial as biological control agents of weedy plants. To prevent the spread of the pest species and properly utilize the beneficial species, it is important to know how to distinguish all of the species and to know where they occur and what plants they attack. This publication provides descriptions and illustrations of six species (three new to science) North and South America which breed in flowerheads of plant species in the sunflower family. New and known distribution and host data are also provided. This information will be useful to APHIS-PPQ and other regulatory agencies responsible for quarantines to prevent the spread of pest fruit flies and for detecting new pest introductions into the U.S.

Technical Abstract: Species of the genera Euarestoides Benjamin (Diptera: Tephritidae) are revised. Euarestoides comprises six species, including three new species: E. abstersus (Loew) (Bahamas, eastern Canada and USA); E. acutangulus (Thomson) (Canada, Chile, Colombia, Cuba, Dominican Republic, Ecuador, Mexico, Peru, Puerto Rico, Trinidad & Tobago, USA, and Venezuela); E. bimaculatus Savaris & Norrbom, n. sp. (Peru); E. dreisbachi Foote (Guatemala, Mexico, Peru); E. pereirai Savaris & Norrbom, n. sp. (Brazil); and E. rionegrensis Savaris & Norrbom, n. sp. (Colombia). A key to the known species of the genus is provided, as well as descriptions, illustrations, distributions, notes on the biology and host plant data for each species.
