There are more than two species. ;) You can just rule out
ornatus

Yes, but
fulvus and
luridus are far east from Belgium.
Remains
ultramontanus (from France according to Fa Eu, but which part ?), not known from Belgium ... yet ;).
Thank you Paul

I see only this alternative:
3. Surstylus in lateral view curved in an arc; epandrial lobe slender and not bilobed (Fig. 13). Prescutellar patch usually well defined in both sexes....... tenellus (Wiedemann)
- Surstylus in lateral view almost straight; epandrial lobe bilobed with ventral lobe itself trilobed apically (Fig. 11). Prescutellar patch often reduced or absent in female ........................... silaceus Chandler et Negrobov (2008: Dipterists Digest 15: 34, British species)
