After eliminating pediculata, you will need to view the cerci surstyli in perfect dorsal and lateral views. The aedeagus is also necessary in perfect dorsal and lateral views. The reason for this is because the genitalia look very similar for many species in the rudis group. hungarica is a possibility here but we need to make certain that it is of the rudis group. it will be much easier to look at the genitalia. https://diptera.info/photogallery.php?photo_id=10761 since you have a pinned specimen, do you mind revealing the genitalia? i just use a pin and pry it out but this is not good if the specimen is dry.

I see yellow pv on femur 3. Accroding to Dr. Rognes, the ventral side of tergite 3 will have mostly black hairs on Pollenia angustigena. If you see mostly yellow/golden hairs, then it will be Pollenia hungarica. Genitalia is best for Pollenia of the rudis group. John and Nini. Naturalists not experts.
