From the Syrphidae mailing list (again):
Dear all,
At the age of 83 Jan Lucas died last Tuesday. He was a good Syrphidae taxonomist and an extraordinary collector. Many newly described species from Europe are at least partly based on material collected by Jan. He was the last living member of a group of three that really inspired and excellerated Syrphidae research in the Netherlands in the 1960's and onwards, together with Volkert van der Goot and Bob van Aartsen.
Jeroen and I intend to write an In Memoriam for Volucella, including bibliography, described species and species named after Jan. We appreciate contributions if you have interesting stories to include or names to add. I think we have a rather complete list of his Syrphidae publications.
