There are also some new records (from 2007) in northern Switzerland. I know only Thun (Lake Thun, near Interlaken), what is refered by a photo on www.galerie.hymis.de
. Also I thought that there are more records from NW-Spain, but I don't remember details.
Do you know Michael Kuhlmann, an expert for Colletes, now in London, British Museum? He will have these information. I may give you Email adress by email. My email: christian(@)bembix.de
