The parafacial does look dark and hairy but I can't see the lemon-yellow halteres that I would expect to see on P.barbifrons. It would still be my best guess but maybe Theo can comment on it :)

Look at the second pic, the parafacialia are all hairy, so it definitely is barbifrons.
The yellow halters are covered by the calyptrae.

Thanks
On this "bad" photo, I think you can see the yellow halters.

Looks very convincing :)

I'd go for that too, easier to see than the parafrontal bristles - even if I copy Pic 2 and then work on it with Paintshop all I can see is something that are probably bristles.

Right.
The point is, however, that in pusilla there is nothing, except 1 row of bristles. So 'anything more' implies 'not pusilla'

By the way, the last pic shows the hairs on parafacialia better.
