Hello,
Xysta holosericea suits her well, according to the interactive key at http://www.tachin... used with parcimony and this post: https://diptera.i...ost_209644
Let me know if you're ok with it. It could be a very interesting observation.
Also posted on a french forum insecte.org and on iNaturalist.

I need to check my collection. Pinned, ID is trivial due to asymmetrical genitalia.

Sadly I did not catch it, but its last tergite appears to be asymmetrical on the last view. Even the dark patterns on the last tergite are identical to those of this specimen : https://diptera.i...ost_209644
