And once again, things are getting crazy... But that's the exciting thing about fly observation. So we learn from https://diptera.i...d_id=76397 and https://diptera.i...d_id=15557 that - either generally or at least in most cases - A. confusanea has midtibia with 1 ad and hind tibia with a bit of orange colour, and A. liturata has midtibia with 2 ad and black legs. Best differences are in male genitalia, and A. liturata is more common.
That's all fine but difficult to apply to my photos. I think there are 2 ad of different length. The legs look black, though I also have a picture (not shown here) where the hindlegs appear reddish. I think that is a reflection from the flash. A. confusanea has not yet been confirmed in our region of Berlin/Brandenburg. So it remains A. cf. liturata. Thanks for the interesting hint!
