I think this is Norellisoma spinimanum,
but i can't find the name in the checklist for the Netherlands. Does it perhaps has a synonym name?

Of the three British species of Norellisoma, spinimanum is distinguished by the arista being short plumose rather than pubescent. It is hard to see on your photo, but the left arista, though out of focus, does look plumose.

The only synonym in the 1998 British checklist is nervosum, though this was a misidentification rather than a true synonym.

thank you John,

At first i thought of a new species for the Netherlands, witch was wishful thinking, since I found the genera in the Dutch checklist as Norellia, including 7 species.

At real pixel-size the arista seems short plumose indeed. What a sharp eye you must have!

Thanks for your info and id,

Klaas
