Thank you very much Stephane!

I was inwardly hoping that the prominent feature of the ventral abdomen would make it possible to get down to the species.

A search in Fauna Europae listed 45 Fannia-species for Norway. I did the pain work to scan thoroughly through all the pics I could get up for them via Google images.

It possibly boiles down to Fannia sociella (female).
There is a pic with a quite similar habitus in BOLDSYSTEMS (I am not sure if I am allowed here to link directly. . .)

What do you think?

Best regards
Dirk
