I caught this Eupeodes goeldlini/bucculatus in Turnhout (Belgium) on 3/04/2012.
The basal cells are completely haired with microtrichia, which is a distinguishing feature for E. goeldlini.
This key (
http://www.prodin...720590.pdf) sais they can be distinguished by the shape of the black spots on the tergites.
But I have read that the genitalia are the only relaiable way to distinguish this species.
Can I be sure that this is a goeldini or do I have to examine the genitalia?

Good question, but unfortunately no easy answer.
Eupeodes is notoriously difficult, and it is sometimes not possble to put a name on specimens, even with the existing keys.

Thanks for the answer Gerard.
Are there any good keys for the genitalia of Eupeodes?
