Indeed, it is S. glabrifrons. I studied the 'books' during the last few weeks and the combination of shining frons, white halter knob and the imaginary line through cross vein dm-cu intercepting the costa distal of R4 are characteristric of this species. Scenopinus fenestralis also can have clear wings and pale halter knob, but its frons is not shining and the legs, in particular the hind legs are dark(er).

Sorry, I got my wires crossed. The character mentioned by Krievosheina (1981) about the imaginary line through cross vein dm-cu is actually the wrong. It should run distal of R4. So the only characters pointing to glabrifrons are the frons the the halter knob.
My apologies Pablo, for not having responded to your posts before, but had not received notification of them.
From my limited knowledge to understand your detailed explanations, I have believed that this diptero is, S. glabrifrons, and so I have edited the title of the entry. If I got it wrong, please, tell me to correct it.
Very grateful for your attention and help in identification.
Kind regards, from the south of Spain,
