Yes, there is, but I can't find it right now. Maybe somebody else can, otherwise I'll maybe get back to it!

I wonder if this can be updated to give the current position on the two species?
Please look at my thread..
http://diptera.in...d_id=40489
...with particular notice to:
As the latest edition of Mark van Veen keys "Hoverflies of Northwest Europe" states that the two species "may be a single species" but gives keys to both (females included), and the keys post date both the thread you have linked to and the thread here which I have linked to, someone out there might know the latest on this.
