[Syrphidae] recent keys and taxonomic papers for European Syrphidae

[Peter Hondelmann]

Dear all,

after many years of hiatus, I want to restart Syrphidae activity with a 
focus on determination of north-west European hoverflies. Therefore my 
question, if there are important changes in taxonomy and new essential 
keys after van Veen's great book and it's revision?
A literature list with keys and taxonomic papers would be perfect ;-) 
(and all what was sent via this email list I have).
Thanks a lot for any information!

Peter
