The only genus in the Syrphini that has long hairs on the lower lobe of the calypter is Syrphus and that is used to separate the genus from all related genera.
Another feature you will find in most Syrphus (but not in all and also in some species in other genera) is a dull mesonotum. Many Syrphinae have a strongly shining mesonotum, sometimes with two whitish stripes near the anterior margin. When you look carefully you can sometimes discern very vague stripes in some other species.
A character of Eupeodes not found in Syrphus is the margined abdomen (see thumbnails below). A second character (but be more careful with this one) is that Eupeodes has paired spots on the tergites that may merge to form bands. And that is where you have to be careful. (Comments by Paul Beuck).
See further comments regarding separating Eupeodes from the similar Syrphus HERE
In Eupeodesthe yellow markings don't quite reach the edge of the abdominal tergites, and the abdomen is strongly margined. Taken together, these rule out Epistrophe, whose markings usually reach the edge, and are usually unmargined. The exception is Epistrophe (Epistrophella) emarginata, but it doesn't really look like Eupeodes. It is really variable though, so it can make IDing Syrphini by eye tricky. (Comment by Andrew Young)

in Eupeodes (left), abdomen had a black margin, lacking in Syrphus (right):
