Hello! I caught this in Hungary.
About the size and place of pruinosity in the scutellum and thorax, and size I excluded most of the species. But I canmt decide between two:
- Gymnosoma clavatum
- Gymnosoma rotundatum
I pulled out the genitalia, but I don’t know which one is the cercus. In the forst picture, I circled three things. Could you tell me please, which one is the cercus? The yellow the green or the red?

Cercus, syncercus in this case, is in the red circle. It excludes clavatum.
