I have been passed a very confusing Eupeodes in extremely battered condition. As far as I can see it is not nielseni/nitens nor is it corollae, latifasciatus or luniger. I end up in the area of bucculatus/goeldlini but it seems not to fit either. My possible interpretation is E. duseki but I am far from convinced and as it is not a known British species I have no voucher material against which it might be compared! I wonder if anybody here can point me in a sensible direction or point out the foolish mistake I have made!
The person who captured the specimen ran it to parasyrphus but as far as I can see the anterior anepisternum is bare. Unfortunately, there are some pale hairs on the margins of tergites 2-5, and unlike most Eupeodes they are quite long (which made me think of E. nitens).
