Hi Steven and others,
very nice to see that Dasysyrphus is still en vogue ;-)
Thinking from the hoverfly community perspective, it would be very good,
if the people working on Dasysyrphus (Steven, Robert, Dieter, Jeff and
surely many others) could make a joint effort.
Please do not decribe single "new" Dasysyrphus species. Please try to
achieve a thorough revision of at least the Western Palaearctic area
(Holarctic would be better, though ;-)).
Otherwise I fear we would have to deal with a mess of old names, new
names, synonyms etc. for many years. We already had that in some other
genera, and I think it would be time to join forces and prevent such things.
All the best and good chance,
Frank
P.S.: Ximo, the Chrysotoxum paper is in the attachment
