Any idea about genus?

wow!! This is the FLY. :) It seems a very strange Stratiomyidae! Acroceridae have no closed wings like this...

No, not Stratiomyidae, but another family.
It is called Mythicomyiidae, and it used to be in the Bombyliidae as subfamily Mythicomyiinae!
Maybe David can tell us more about it?
Greetings,

new family for diptera! :)
Van Veen could help as well. :)

Certainly Mythicomyiidae. Unfortunately i cannot see wing venation clearly so deducing genus is not easy (it is a species i have never seen). My best guess (and it is a guess untill i see a specimen) is
Glabellula, the only species recorded in Spain is
sufflava but there are likely to be undescribed species in this underworked family of tiny flies (my favourites so very please to see these images).

Thanks David! (and Gerard :D)
I post another photo (I don't have more :() I think the wing venation is a bit more clear here...

Your third photo shows the wing venation much better and i can now see that it cannot be
Glabellula. Jorge, although the wing venation fits
Cyrtisiopsis , this genus has a more prominent backward extention of the rear of the buccal cavity, also, as far as i know, they tend to have long a proboscis (see Oosterbroek 2006 fig 142). Javig's fly is a
Platypygus. There is only one species listed for Spain vis
ridibundus. I have a female specimen myself (i was away from my collection yesterday so unable to do a direct comparison), also from Sierra Nevada area, which looks much the same except it has blackish mesonotal stripes, a longer proboscis and pale frons spots joined to yellow on face. My specimen was named
ridibundus by David Greathead but it does not fit the description well. This genus is sorely in need of revision and there are certainly unrecognised species in Spain, so it is unwise to name to species untill this is done.

I pass on the following from Neal Evenhuis
"It is the common and widespread
Platypygus
ridibundus. The thoracic pattern is variable and
can be darker in some specimens."
