Two new European long-legged hoverfly species of the Eumerus binominatus species subgroup (Diptera, Syrphidae)

Abstract

<i>Eumerus</i> Meigen (Diptera, Syrphidae) is one of the most speciose hoverfly genera in Europe, with several species groups recognized within. As part of the <i>tricolor</i> group of species, a subgroup of long-legged representatives stands out. We name it <i>Eumerusbinominatus</i> subgroup and provide descriptions for two new European species which belong to this subgroup: <i>E.grallator</i> <b>sp. nov.</b> from mainland Spain and <i>E.tenuitarsis</i> <b>sp. nov.</b> from Lesvos and Evros, Greece. A key for all five recognized species of the <i>binominatus</i> subgroup is provided.
