Hi,
found indoors, Vienna (early April). Could it be Scatella palustris?

The hairy face, single fronto-orbital bristle and the costa only extending to R4+5 all add up to Scatophila.

Thanks Tony! I cannot find a key for the species, can you help out?

I think your best option is a paper by Jens-Hermann Stuke (2010). Die Uferfliegen Niedersachsens und Bremens (Diptera: Ephydridae). Entomologische Zeitschrift, Stuttgart. 120: 171-189 and 195-222. [Scatophila is on pp.213-216]. If your specimen is a female, it may be more tricky. I think I have a copy I can send you.

Using the key Tony provided, I reached tentatively S. caviceps.
The scutellum appears to me dusted at the basis and at the tip.

want to bring this old ID request back, adding an additional image:

The costa seems to reach M, would this make this species Scatella instead of Scathophila?

To me, the costa ends at (or just slightly beyond) R4+5 - the next section (to M) is very faint.
