Özet

With more than 300 described species, the genus Eumerus is one of the largest genera of hoverflies (Diptera: Syrphidae). In this paper, we define the Eumerus bactrianus subgroup and revise the subgroup in Europe for the first time, providing an illustrated key for its European species. We describe three new species: E. banaticus Nedeljković, Grković & Vujić n.sp. from Serbia and Romania; E. bicornis Grković, Vujić & Hayat n.sp. from Greece and Turkey; and E. bifurcatus van Steenis & Hauser n.sp. from Spain. Species of this subgroup exhibit a distinctive apomorphic morphological feature, i.e. the bifurcated posterior surstylus. We discuss the distributions of seven Palaearctic species of this subgroup: E. bactrianus Stackelberg, 1952, E. pannonicus Ricarte, Vujić & Radenković, 2016, E. turanicola Stackelberg, 1952, E. turanicus Stackelberg, 1952, and three species described here. Molecular species delimitation, which strongly supports our morphological results, is based on maximum parsimony analysis of mitochondrial COI sequences.
