Galicia (NW Spain), deciduous forest, 1000m, july 2007, 8mm.
Please, any comment?

Could be Rhymosia but I'd need to have the specimen to be certain.

Thank you again, Paul.

Rymosia does not look right to me, sc terminating in R1(ending free in Rymosia). i would suggest Allodiopsis sl. (if tips of frork veins with setulae) or Brevicornu (if these veins bare) but Tarnania and Allodia also possible. Check tips of fork veins for setulae then dissect and photo genitalia, that will probably sort it out.

I thought that most of the genera you mentioned have species smaller than 8 mm, though I am not certain about Tarnania.
I hope I can examine the actual specimen soon. ;)

for Brevicornu and Allodia i would agree, none of my specimens are large. Tarnania can be large but the single species i have does not look like the photo. However, Allodiopsis rustica (Edwards, 1941) is a large species and looks very like the photo. In GB this is the only one of the three species that is at all frequent.

I have not checked against my specimen of Allodiopsis but I thought the genitalia were smaller. Still, you might be right.

Thank you very mutch, Paul and David.
I can see small setula in the places marked red, in the rest the veins are bare:

And a bad photo of the genitalia in place.
I leave the extraction to Paul, I am not confident with my technique.

the genitalia confirm Allodiopsis s.s. and i would say 95% rustica. However, from this view i cannot rule out domestica, need very good ventral view of genitalia showing details of structure between the black sclerotized lobes.
