Abstract
Agromyza Fallén (Diptera, Agromyzidae) is a genus of leaf mining flies, including species with high economic importance. The knowledge of this genus is very poor in the neotropics, with 12 known species, only six of them recorded from Brazil. This paper describes two new Agromyza species from "Cerrado" and "Pantanal" biomes and records three other species represented only by females that could not be identified to species level. We also present a taxonomic key to segregate the 14 Neotropical species. The specimens were collected in Mato Grosso and Mato Grosso do Sul states and are deposited at Museu de Zoologia, Universidade de São Paulo (São Paulo, Brazil) and Museu Nacional, Universidade Federal do Rio de Janeiro (Rio de Janeiro, Brazil) collections. The adults were photographed and the male terminalia were dissected and illustrated.
Highlights
The species of Agromyza Fallén (Diptera, Agromyzidae) are mostly leaf miners, with a few known as agricultural pests, known to attack a wide variety of cereals such as barley, oats, rye, wheat and corn (Spencer 1973a)
This stridulatory mechanism is present on the anterior lateral margin of the tergites 1+2 and on the posterior margin of the hind femur (Boucher 2010) and is one of the apomorphies that support the monophyly of the genus (Scheffer et al 2007)
This paper describes two new species of Agromyza found in Mato Grosso and Mato Grosso do Sul, in “Cerrado” and “Pantanal” biomes respectively
Summary
The species of Agromyza Fallén (Diptera, Agromyzidae) are mostly leaf miners, with a few known as agricultural pests, known to attack a wide variety of cereals such as barley, oats, rye, wheat and corn (Spencer 1973a). The number of Agromyza species in the world is around 200 (Boucher 2010), 12 of them recorded from the Neotropical region and only six known from Brazil (Martinez and Etienne 2002).
