I must say that you should wait for more experiences therevidologists - but I think this fit a female Thereva handlirschi well - golden colour, large shining black spots on frons forming a broad band from eye to eye, single row of anteroventral bristles of hind femora.

Hello Viktor,
thank you for your answer. If those are the characteristics of T. handlirschi, it seems to really fit well. I have another picture, where the shining black band is a bit better visible. For the femura I don't have another picture.
I will change the subject, so perhapt the attention of a therevidologist can be drawn.
Greetings,
Michael

There are 2 pairs of DC bristles, so it can't be nobilitata.
Handlirschi is then the obvious choice

Hello Theo,
thank you for conformation. What are the CD bristles?

It is DC, dorsocentral, other then the name suggests, these are the sublateral bristles on the thoracic dorsum.
In plain english, if you look at the thorax from aboven, the central pair of line of bristles is actrostichal (ACR), then outwards of that about halfway you have dorsocentral (DC).
Have a look at the glossary as well !

Hello both,
thank you for your explanation. I think I can now even see those bristles on my photos. It's the long black hairs at the side of the thorax, which are nicely contrasting to the golden fur.
Greetings,
Michael
