Interpretive Summary: Fruit flies include some of the most important pests of fruits and vegetables worldwide. The majority of the pest species are exotic and are threats to American agriculture. To prevent their introduction to the U.S., knowledge of the taxomomy, distribution, and biology of all fruit flies is critical. This includes how to identify them, knowing where they occur, and which plants they attack. This paper describes two previously unknown species of a group that includes pests of apples, cherries, eggplant and tomato. Identification tools (descriptions, illustrations, identification key) are provided to distinguish them from other species of the group. This information will be useful to APHIS-PPQ and other regulatory agencies as well as scientists studying the biology of these flies.

Technical Abstract: Rhagoletotrypeta chapecensis Norrbom & Savaris, new species, and R. gelabertae Norrbom & Savaris, new species, are described and illustrated from specimens from southern Brazil (Paraná, Santa Catarina) and Paraguay, and from the Dominican Republic, respectively. The larvae of R. chapecensis develop in fruits of Celtis iguanaea (Jacq.) Sarg. (Ulmaceae). A key to the species of the xanthogastra species group is provided.
