1. Thank you Robert. I'd wait a little bit more;)
2. This matter needs more light, may be Robert ask Adrian Pont, may be Tony or Kahis reply.
In our Gellery comment under Phaonia rufiventris is:
"The thorax is too dark to be pallida and too yellow to be subventa, so I am sure that you are right it naming it as rufiventris"
Is there only this vague way to ID? As far as I understood Pont's comment it doesn't much matter 1 or 2 presutural ac are? (In case of Juergen fly - 2). Any idea?
