It's an asilid, or 'robber fly' :)
On another subject though - could you please use better descriptions in your Subject title? Just describe the fly a little because it is very confusing when 3 threads have 'what fly is this?' or like 'id please' ;)

Which Species?

If you change your subject to 'asild fly' then it will attract the asild experts :D

No one knows what Genus and species is this Fly?

I would think someting like Neoitamus cyanurus... but it's risky. There are many species on the Iberian peninsula. Collect it, I would suggest ;)

I'd say that the size is probably too big for
N. cyanurus (comparing with the prey in the first picture) and I cannot make out the bent hairs on the posterodorsal part of the head, so probably no
Neoitamus at all. Just wait for Danny.

I have to agree with Paul... I didn't look well the first time. Also the coloration on the legs don't fit Neoitamus.. :(

Not Neoitamus I think.
Neoitamus females should have characteristic elongated genitalia and also some special hairs bending in 90 degree in the occiput.
Also if I understand correclty, Neoitamsus spp are early Asilids, that are primarily found in May and June. (as far as Central-Europaean species are concerned)
I also think that naming a Neoitamus to species is quite challenging, and requires special knowledge.
I do not know what species is shown on this figure. In my opinion this is a female of a group containing Tolmerus Machimus etc.
Would be nice to get Danny's opinion on this.

Or Eutolmus? The problem for me is that we have so little number of species among Neoitamus and Eutolmus and such... really would be great to be able to identify Iberian Asilidae, because I visit Portugal on a regular basis! At the moment I try not to collect them too much :|

Hello,
Gabor is quite right. This is a female of the Machimus-group (with so many species in the mediterranean area, many of them undescribed). Eutolmus females have a different ovipositor with the cerci not free but "incorporated" in the ninth tergite.
Greetings, Danny Wolff
