I've read the description from Meigen and the keys from Tschorsnig. I agree with some of the data but not all of it:

Head is Gonia-like, pearlgray with a dark shimmer.
antennae almost as long as the face. Arista thick with hair-like tip.
four dark stripes on thorax (a bit broken but Meigen's drawing looks broken)
no apical scutellar brsitles but two bristles before the apex.
wings have a brown tint.
pre-alar bristle looks longer than the anterior intra-alar setae
cheeks have hair present.
frons is deep black (but grayish at various angles)
eyes look bare to me.

I assume this to be Baumhaueria goniaeformis unless you say otherwise.
