I have been encouraged to speak out ;) so I am going to do so. I might regret it later though :D :D

To me, this is one of those Lithoeciscus sp. Black legs... perhaps heydenii?? However several little things don't seem to fit with description. But hardly any Iberian Asilid seems to fit with description :@ :( ;) so it doesn't come as a surprise ;)

Ramón, the good news... we are already on it!! ;) Well, Reinoud is! My experience and previous knowledge on Asilidae only allows me to be closer to the scullion of the chef :D :D :D But learning a lot anyway :) And very happy about it! :)

The bad news... it is going to take a very long time :( We plead for loads of patience.

But a year ago very few people had any idea of what a Lithoeciscus might look like, so I think something positive is coming out of all the effort :) :) even if I am wrong and it is not Lithoeciscus. Difficult stuff anyway...

Lithoeciscus has been split off by Bezzi > L. heydenii. Used to be Holopogon. Bezzi also noticed that some other species were very close, like H. rugiventris, and even Cyrtopogon tenuibarbis a.o. In Spain a lot of such specimens have been collected and most seem to be very close. One of the remarkable differences with the "regular" Holopogon species is that the hind tibiae and metatarsi are not so swollen. We are studying a lot of them but we still have to compare them with type material. This may take a lot of time.

But I think Piluca is very close, I would say Lithoeciscus (Holopogon) cf heydenii too

Ramon, did you collect any of these specimens? Do you have more pictures?
