According to "Checkliste der Dipteren Deutschlands" there are only two species present in Germany: P. seminationis and P. lugubre. So you should have a closer look to the supraalare: 4 = P.lugubre or 3 = P. seminationis (see Hennig, W. (1945): 48. Platystomatidae. - In: Lindner, E.; Die Fliegen der Paläarktischen Region.)
