This male Hybomitra was 18 mm. Are spieces possible to tell?

Was it really so large? The only guess that came to my mind was Hybomitra tropica, but I've never seen this species. So let's wait for Theo!

18 mm. is very large indeed.
Given locality and date, it must be an early spring species. Pity we can't see the palpus. Best guess (stress on guess) is H. nitidifrons.

Yes, that was my first thought too, but isn't 3d antennal segment too dark for nitidifrons? So I opted for tropica. By the way, CLM say about tropica: "One of the earlier spring species with a maximum occurrence in late May and in the beginning of June."
Anyway, with these images all is a guess, I think:|

Thanks to Sergiy and Theo for looking at my Tabanidae.
This one was big and I can se in a Swedish key (only females) that both tropica and nitidifron could be up to 18 mm.
If I search at Swedish "Artportalen" tropica is found in Southern part of Sweden but nitidifrons of found in my part of Sweden an in second half om May and first part of June.
