Witch Tabanidae have i seen today in the Netherlands in the village of Nieuw-Vennep near Amsterdam? I think it's a Haematopota and than i guess the crassicornis. Am i right?

It is certainly an Haematopota, but I always find it difficult to say which species. I would like to have a better lateral view of the antennae.
I do not think it is crassicornis, because it appears that the 3rd segment is too brownish.
I hope Theo Zeegers will let us know his opinion.

I made an enlargement of the antenna. I hope it will help

I couldn't give a definitive opinion. It is a bit late in the year for crassicornis, moreover the first antennal segment seems too elongated. However, the wing pattern is quite bold, suggesting it is NOT pluvialis.
It might (repeat: MIGHT) be subcylindrica.

Definitely would need more angles to be able to say moren.
