A confusing Muscid/Tachinid that looks a bit like a Phaonia sp

I thought this looked rather like several of the Phaonia species, except..
a) venation wrong
b) rows of very large spines on the abdomen
c) abdomen looks far too narrow (in fact it looks oddly truncated as well, as if sliced off)


However, it has a lot of similarities to images I've seen of (e.g) Tachid Macquartia grisea.
Except that whilst mine has large spines at the posterior boundary of each tergite, the above tachind has an extra row in between as well.

So I don't know what it is.
Enough stabbing in the dark.
Quite small : around 6-8 mm.
And I don't have any more reasonable images because the leaf it was on was moving too much.

Try Solieria - Tachinidae

Yes!
Thanks very much, Nigel.
That is visually a good match (though it's not easy to find genuine images).
I found one on Dipterists Info which was actually identified to species level, and the only obvious difference was the colour of the scutellum.
So it just may be possible to take this further. I shall contact Chris R, in hope rather then expectation.

Yes, definitely a Solieria but they are quite tricky to identify from photos because the first couplet asks for the frons/eye-width ratio wink
