Allophyla?
Matthias, could this be the similar genus Allophyla? Marshall, photo 512.7 (1) shows Allophyla, and it looks to be real similar to Suillia, but to my (non-expert) eyes looks less robust overall--perhaps because it is smaller? Other characters of this photo are similar to Marshall's photo--dainty legs, spiny setae also rather thin compared to photos he shows of Suillia.
I am certainly no expert on flies--it just seems this photo stands out as being different from the other ones placed in genus Suillia, and it does resemble the photo Marshall calls Allophyla.

Suillia
Allophyla has a postpronotal bristle (at the anterolateral corner of the thorax, right behind the head). This bristle is absent here, which characterizes Suillia. Otherwise the two genera are virtually identical.
