8mm flies on intertidal mussel shells on a shore in Cornwall UK on 11.9.18

Males were courting by opening wings at intervals.

I think these are Fucellia maritima, the more common of the 2 UK Fucellia species, with a more southwesterly distribution than the other species F. fucorum, which I read has black tibia which I don't see her, but I'd wecome feedback/comment on my tentative ID.

I can confirm that it is not F. fucorum: either tibiae yellow and av seta on t2 absent

Many thanks Nikita for ruling out F. fucorum, though I now realise that F. tergina is a possibility in the UK as well as F.maritima which is slightly more common. I doubt my photos are detailed enough to be sure which this is.

Is there any lateral image (never mind how bad) to check width of gena?

Sorry, no really lateral view, the only other shot , attachedhere is also slightly from above so probably does not help.
