I think it's a female Beris morrisii

I think it's Beris chalybata (female). B. morrisii has a narrower frons.

I think there's a big shadow on the eye making the vertex look bigger than it is. B. chalybata's anterior metatarsus should be "mostly or completely dark". B.nigra could be an alternative...

You're right. it's Beris hauseri (female)
Thank you very much

Beris hauseri is now treated as a synonym of Beris nigra.

See: Zeegers, T., 2021. Notes on the types of Beris Latreille, 1802 (Diptera, Stratiomyidae) in the Meigen collection. - Linzer Biologische Beiträge 53(1): 431-435.

but the tibiae are completely yeloow ?
I don’t see why it could not be chalybata.
