Abstract

An ongoing investigation on the Greek hoverfly fauna using adult morphology has revealed new species within three genera. In this study, the knowledge of the Mediterranean hoverfly fauna has been enhanced by describing the following species: Cheilosia candida Vujić et Radenković sp. n. (Pindos Mountains), Paragus thracusi Radenković, Likov et Vujić sp. n. (Rhodope Mountains) and Psilota aegeae Vujić, Ståhls et Smit sp. n. (Lesvos island). Diagnosis of new species, as well as identification keys to the Mediterranean species of the subgenus Convocheila Barkalov of Cheilosia Meigen and the European species of the genus Psilota Meigen have been provided. Additionally, mtDNA COI barcodes for the members of the Psilota atra group (except Psilota nana Smit et Vujić) have been given. In addition, the taxonomic status of Psilota anthracina Meigen has been discussed.
