I'm wondering if this might be an Egle of some sort. It's at least superficially similar to the only example in the guide:

Egle atomaria?
I suspect Egle atomaria, which is distinguished from relatives by having shorter hairs on the thorax. I would need to see a female of another species side by side closeup for comparison. Possibly Michelsen's revision offers more advice. I only have Griffiths'.

Griffiths did not know how host specific these are. It is common to collect multiple species of Egle from the same host, so they are not all limited to a single host species.

Different species
This is not the same species as mine. Hairs are different in various places.

I didn't imagine it was the same species...
but do you think it's the same genus? And are there details I should look for to confirm?

Can't tell
I don't know. The other fly seems to have four postsutural dorsocentral bristles, compared to three on nearly all Anthomyiidae other than a few species of Egle, but I see three on this one.
