Correct ID? Met this one in forest, near river. About 7-8mm. 25 of june. No tripod = no very good pics...

Gymnosoma certainly - but not sure which one :) You need to be able to see the dusting really clearly and it helps to have specimens so you can see genitalia ... but even then it can be tricky.

Okey, thanks for the info... Getting the specimen would be kinda hard... The kid was taking a bath, and stepped on this one when getting out of the water :o It was good looking before that tough ;)

Well, if the genitalia and mesonotum are still in tact it might be possible ... depends now much stuck to the kid's foot ;)

it kinda looked like a pancake with orange on ;)
Anyways, searching norwegian sites, I only see
Gymnosoma rotundatum mentioned, but then again, that may only be because thats a common sp. up here so people take a chance on it... I couldnt find any info (quick google) about what sp's of Gymnosoma that lives up here...

It could be that yours *is*
rotundatum but I think an explanation for the lack of information on the net might just be that it's possibly an assumption -
G. rotundatum is perhaps the commoner species and it's easier for novices to "identify" a
Gymnosoma as
rotundatum, rather than delve deeper into the genus. ;) Also, remember that phasiines have been expanding their distribution north and it could be that more species have moved into the region :)
Just a quick look through Fauna Europaea showed this list of alternatives:
G. clavatum:
