Is it possible to confirm or deny the correctness of the definition based on such a photo? Found in June 2023. Western region of Ukraine.

Much, much better. Seems to be the male of Silvius latifrons, see the other post.
Did you collect any of this material ?
Great find (if correct).

Amazing, well done !!
That said, it is now clear that that second antennal segment is elongated, not short as it appeared to be in the older pics. This was the 1 % doubt.
So it 100 % is Nemorius vitripennis, which is still a great find, but not as spectacular as latifrons. The northern border of its distribution is (or was in 1972) “ ….. and the Ukrainian Transkarpathians, Chust region”. if that makes any sense to you.

I noticed about ten specimens of these tabanidae (they were sitting on the road bridge over the Tisza River) twenty kilometers from the location you mentioned here (Chust).
so, thank you, Theo, for your help in identifying the species.

Tisza, so that is at the Hungarian border ? Nice.

Yes, <20 km to Hungarian and 5km to Romanian borders.

Absolutely correct!
