I think that you can be confident that this is a Somatochlora species, but it's really not possible to make more than a guess at which one (S. metallica might be the most likely).
I probably agree but the location put me off as there are other species that we do not get here.

The general "jizz" still suggests Brilliant Emerald to me though, the other species that would be likely to occur in the location tend to be darker, or have pale spots that are usually noticeable, and/or have a different abdomen shape (I'll see if I can post a few shots in the next couple of weeks for comparison).
