Seen in Umbria, Italy, late October
Unsure if F.aurea or F.ruficornis (or maybe even another genus?).
Help apreciated

Hello leonvdn

You are correctly suggesting that the genus is Ferdinandea. In Ferdinandea the interesting species have the stigma bicolourous or the arista red. The remaining species, the most common, has the yellow stigma and the more black arista. For a key see: http://www.dipter...w_2011.pdf
I arrive at Ferdinandea cuprea. Arista black, abdomen with tergite three and four only anteriourly dark bands and stigma entirely yellow.
The shown specimen is somewhat off due to the entirely yellow legs, however in my collection I have specimens with entirely yellow legs.

Greetings,
