Hi Sundew,
thank you very much for the detailed answer. Your paper is very welcome and would be helpful for me. I have only the old book with the key of Gerald Bothe where the flies are hidden under names which were valid 38 years ago.
I will look again to all picture of that fly.
Best regards, Marion
