RESUMO
ABSTRACT Coenosia attenuata Stein (1903) is a predatory fly that is commonly found in greenhouses and open fields preying on whiteflies, leafminers, psocopterans and other insects. The species is widespread in the Old World and its distribution has expanded in recent times to Neotropical countries including Chile, Colombia, Costa Rica, Ecuador and Peru. We report here for the first time the presence of C. attenuata in Brazil, occurring in different sites in the State of Ceará (Northeastern Brazil). Expansion of the distribution range of this muscid to the eastern parts of South America opens up the possibility of applying the beneficial predator as a biological control agent for protected crops of the region.

First record of Coenosia attenuata Stein (Diptera, Muscidae) from Chile, with biological notes. Coenosia Meigen (Muscidae, Coenosiinae) species are known as predators of other insects and play an important role as potential biocontrol agents. Six species of Coenosia have been recorded in Europe preying on insects pests, one of them is Coenosia attenuata Stein. This species was recently recorded from the Neotropical Region and is herein recorded for the first time to Chile. Biological notes were included.
