Reasoning (by Matthew Vosper) that this could be borealis on similar observation : https://www.inaturalist.org/observations/26296912


... 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)"

this would leave E.borealis?
