Well.... I've never seen it, but I don't think it is
cisalpinum.
Did you compare it with
Chrysotoxum festivum?
Greetings and thanks for your mail about F. fumipennis!

Thanks André
yes , I have compared: festivum (male) has black frons, side border of the abdomen yellow and black, antennae: 1°, 2° and 3° segment of equal length.
Faunaitalia signale from Sardinia (not surely reliable) only: intermedium, fasciolatum, bicinctum and cisalpinum
I am not surer than the 3° segment =1° + 2°.

I have been checking again and must agree with your ID, even before your reply. Been away though for a few days. Anyway, it convinced me that this is
cisalpinum! Hope to find it too some day, a wonderfully nice species

Hope you will add it for the gallery?
