 Have a nice Day. One Question please. Is this a Gonia- Species? Can it be determined more precisely? I would be very grateful for a reply.
Discovery data: Austria, Lower Austria, Tattendorf, 220m, vineyard, 31.10.2025, size 6-8mm

Kind regards Karl.

 I am very hesitant to say anything about this fly, but it reminds me of Pseudogonia rufifrons.

 Hello piros and Theo thank you for the Answer. If I understood the translation correctly, this is ( cf. Pseudogonia rufifrons).

Kind regards Karl

 Hello Theo thank you for the Answer, and that it is definitely Pseudogonia rufifrons. I'll remove the "cf." right away.

Kind regards Karl.

 Second antennal segment looks short for P. rufifrons ?

 I don't see the issue, cf. fig 140.3 in Cerretti.
Maybe in the key you confused "arista" with "antenna" ?

 You’re absolutely right, Tony – I read (Tschorsnig) "antenna" instead of "‘Arista".
Have a nice day

It is sad news. I read him a month ago, as he replied to me about a wrong identification. He was brilliant, as always.

I have just received the very sad news that Peter Chandler has died after a fall at home yesterday. I have no other details at the moment. We shall miss him terribly.
