Probably a female N. appendiculata, but the key identifying feature is missing from the photo: did you see a dark, inverted “U” on the anatergite?

but the pterostigma dark rules out appendiculata, isn't it?

Not necessarily, you can refer to the key by Stubbs and Kramer (2016) or the French key by Rojas and Quindroit (2026) for guidance.

Thanks a lot!!
I've used the first one; I don't knew the second one, but I've just use it and It's fantastic by the way. In the photos i have, I can't see the "black inverted U", so it will be difficult to propose anything at species level, I think.

I've noticed the confluent bands on the scutum and tried to find a Nephrotoma with this characteristic. It's only a guess as I've never heard about it:
N. sullingtonensis Edwards, 1938, which is recorded for Portugal, Spain, France and the UK and available at the CCW.

There is an annotation at the end of Rojas key in which it comments the similarity of the females in both species (
N. appendiculata and
N. sullingtonensis)

Sounds well - and the stripes are distinctly separated in
N. appendiculata

Nice, totally
N sullingtonensis |t
N appendiculata can indeed have (pretty rarelly) such a dark stigma
