similar

how do you rule out chlorosoma or punctulata from a photo then? I've only been able to get mine to genus so far.

Fair point. I have

Fair point. I have photographed and logged 'viridis' in the same spot before and so, I accepted that this is the same.

Rhogogaster

I agree that it is tricky to be certain of Rhogogaster species from photos, especially as the markings differ between the sexes as well. Ideally it would be good to see a shot from the side and front as well,. However, both R. chlorosoma and R. punctulata should have less black on top of the abdomen (just visible through the wings in this photo) so I think R. viridis is the most likely solution here.

differentiating

Three people see this a R.viridis.
I am 'running' through all the posts of viridis (I may have one). I need slightly more definitive advice about how to differentiate. Is there a websource?
It is difficult to separate one from another, by Martin's criterion, unless one has both to hand. I will post series of close-ups.
