Interpretive Summary: The family Tephritidae (true fruit flies) includes numerous major agricultural pests throughout the world. The majority of species that are pests in the American tropics and subtropics, and that threaten fruit industries in the southern United States, belong to the genus Anastrepha. Because this group contains more than 200 species, precise taxonomic data are necessary to recognize the pest species. In this paper, 3 species, including 2 new to science, are described, and the host plants of the new species are reported. They are the first Anastrepha species known to attack species of Celastraceae which includes plants cultivated for tea leaves, oil, rubber-latex, and medicines,as well as many ornamentals. Identification tools, including keys, descriptions and illustrations, are provided for all 3 species. The ability to recognize them is essential to regulatory agencies such as APHIS-PPQ to prevent the spread of pest species. The information provided will also be valuable to scientists studying the biology and control of these species.
The Anastrepha hastata species group is recognized with three included species: A. apicata, spec. nov. (Costa Rica, Panama), A. cocorae spec. nov. (Costa Rica), and A. hastata Stone (Brazil). Salacia petenensis is recorded as a host plant of A. apicata, and Cheiloclinium cognatum as a host of A. cocorae. These are the first host records for Anastrepha species from the plant family Celastraceae (or Hippocrateaceae, where these plants are sometimes classified). The larvae feed on the seeds within the fruit. Descriptions and illustrations are provided for each species, and their relationships are discussed.
