This one was found sitting on a leaf in decidous forest by a river in the outskirts of Madrid on the 30th October 2011. I think it might be a
Phaonia. Perhaps Phaonia
rufiventris? Thanks in advance for any help!

Hi Stephane, I'm interested how you can exclude Phaonia subventa?

Well, if I'm not mistaken with the pictures, there is only one pair of presutural acrostichal.
Ph. subventa (and
bitincta) should have 2-3 pairs.
Of course, we were more confident if we could see the fore and mid tibia chaetotaxy.

Thanks! Usually I check the chaetotaxy of the fore and mid tibia to distinguish the species, I didn't know the character of the presutural acrostichals.

Very interesting the presutural acrostichal bristles clue. I didn't know about it either.
Here is another picture with more detail of the torax for you two to see it more clearly. And sorry, no chance for the mid tibia chaetotaxy. It flew off before I could get anything better :-(
