Points by @matthewvosper on iNaturalist as follows :
"...nigroventris (not black enough)
.... latifasciatus (spots too well separated)
....corollae (spots don't reach margins)
...punctifer has very narrow spots
....male lundbecki have dense black hairs on a very swollen frons and a very wide angle where the eyes meet (120deg)"
On the Icelandic list this would only leave Eupeodes borealis.
Can anyone confirm as plausible/correct?
