ABSTRACT
The genus Myolepta Newman comprises medium-sized black hoverflies, with yellowish orange abdominal markings in some species. The genus can be divided into several subgroups of which the Myolepta vara (Panzer, 1798) subgroup will be defined here and its species revised. One new species, M. angustifacia sp. n., is described from eastern Siberia. A key to the species of this subgroup is given. Short descriptions and extensive illustrations are provided for all species.

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