I have not got my kewy here, but this is either Norellia or Norellisoma. I think the former.

According the key I have:
Spines on t1 in 2 rows, 5 dc - Norellisoma;
Hairs on arista only as long as base of arista - Norellisoma liturata.

Difficult to be sure, but I think the hairs on the arista may be longer than you indicate. In that case it could be N. spinimanum, which would fit better with size and I think locality...

In my key in case of N. spinimanum hairs have to be "more than two times longer than arista base diametr".
But realy, difficult to be sure.
One more problem: N. liturata given size 4-6 only. There is one more species in my key N. lesgiae of siutable size, but it absents in Netherland and in Czech checklists, so I doubt whether this species is still exist.
