Hi, I think this is a
Hybomitra, but how can females be IDed?
This one was in alcohol for some time, so the coloration might have changed. I can still see three stripes in the eyes, but they are barely visible anymore. Size (without wings) 14mm. Found in June in Wienerwald near Vienna. Could it be
H. lundbecki?

It is not in pretty condition. It has all features od H. distinguenda, note the extensive golden hairs on lateral orange spots.
However ... the first antennal segment seems orange . Is that right ?? Or artificial ?
Habitat might help as weel.
Thanks
Theo

Yes, first segment is brownish or orange:
Here are the abdominal hairs - all are yellow, couldn't spot any black one.
The lower callus is dark brown, but not black, the notopleural node is dark.
Looks like a combination of
distinguenda and
ciureai...
It was found on a meadow surrounded by forest (Wienerwald, 400m asl) - but within a car, so it might have been carried there

Definitely distinguenda. Contra Chvala et al., notopleural lobe is more often dark then yellow in distinguenda.
Habitat supports ID.
