I am pretty sure this is a Chrysophilus, but it was really big compared with all Chrysophilus I have seen. About 1 cm long. I have gone through the keys but I get all mixed up :( The markings on the wing are driving me mad. Help, please!!

Found sitting on lower vegetation by a river in the outskirts of Madrid on September the 22nd 2013.

Thanks for whatever help!! :)

Another view. The tips of the wings are not hyaline. They look a bit greyish :|

And another one.

It is very similar to this one, which could very well be Chrysopilus laetus. However, this group is taxonomically very complicated...

Thanks a lot, Paul |t Chrysopilus laetus has not been recorded in Spain, as far as I know. Which doesn't mean it isn't ;)

Of the species recorded in Spain, I know for sure it isn't asiliformis, auratus, flaveolus and splendidus.

I think it could be pullus or torrentium, which I know have something dark on the wings apart from the pterostigma. But no more information :( so I simply don't know if there is a chance it is one of those species.

After a long search I finally got the description of torrentium. It is very close to cristatus.
According to Narchuk, pullus should have darkened pleura.
So, I have to agree with Paul it is similar to laetus.
What bothers me, though, is the darkened wing tip
