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 from the Amazonian Region are described or redescribed. One of them (A. brunnealata) is new to science, and another (A. hendeliana) was previously confused with another unrelated Anastrepha species (A. longicauda). New distribution records are reported, and the type locality is clarified for A. caudata, previously thought to be from southern Brazil. 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.

Technical Abstract: Three species of Anastrepha from upper Amazonian are described or redescribed and illustrated. They are considered closely related and are placed in the A. caudata species group. Anastrepha caudata Stone 1942 is redescribed based on the holotype, the only known specimen. Its type locality is probably São Paulo de Olivença in Amazonas, Brazil, not the state or city of São Paulo as previously assumed. Anastrepha hendeliana Lima 1934, new status, is removed from synonymy with A. longicauda Lima 1934 based on specimens from Brazil (Amazonas and Rondonia) and Colombia (Caquetá). The female is described for the first time. Anastrepha brunnealata, n. sp., is described from specimens from Venezuela (Amazonas) and probably Peru (Loreto). Anastrepha longicauda Lima is placed in the dentata species group.
