A project to study the species of mining flies, their hosts and, specially, their parasites was initiated in 1985 due to vegetable crops in the Valencian Community. They were carried out several campaigns in which were studied a high number of leafs affected by the Agromyzidas. As a result of the study of their parasites, are discussed in this paper 22 species of Dacnusini included in seven genera. Eight of them and the genus Coloneura Forster are new records for the Iberian Peninsula.
