Hi Jorge !.
Thx for infos :)
It could be S. affinis (if the cerebral hairs , behind the head and over the neck are yellow) or S. umbratica if are black :)

I saw right now the specimen with my 20x loup :) and it is clear that setae behind the head and over the "neck" are black. :) Therefore this is Suillia umbratica. The setae are small behind the head.
I suppose you recall for upper part of occiput = behind the head and over the neck. ;)
In this photo of Nikita seems that the setae over the neck and behind the head are black... http://www.dipter...oto_id=855 but it can be misleading the photo. And we don?t see completely well the upper part of occiput.

ups... I saw gently more above. It is precisely like the photo of cosmin. So, it is S. affinis! But it is impossible to see the setulae at 20x, right? We can perceive them just for the yellow patches! I thought that you are talking about the upper part of occiput that has really black setae . I will upload the photo more later.
Even with magnification that cosmin used it is not clear the setulae.
