Just lets go again though the key (and forget for now all the setae :S)

1 Costa extending ot apex of M1 = correct (go to 2)
2 Hind tibia without approximated av and ad setae in middle = correct (go to 10)
10 Last tarsomere not dilated on any pair of legs = correct (go to 14)
14 Hind tibia whit preapical dorsal + pd close together = wrong(they have to be very close and on the same level, and we see on photo 3 they are not !)
So....Hind tibia without strong and long closely approximated preapical dorsal+pd seta = correct (go to 17)
17 Lower squama usually much longer than upper one = correct (go to 27)
27 it is a female = correct (go to 67)
67 flagellomere without prominent dorsal tip = correct (go to 71)
71 Proepisternum with 2 setae (you sad..) = correct (go to 75)
75 hindtibia with 1 or more submedian pd = correct (go to 76)
76 fore tibia without distinct ad seta = correct (on photo 1 you can see an posterior seta on tibia 1) (go to 77)
77 femora partly darkened (fore femur is dark) , mid and hind femora darkened apically and flagellomere dark = correct ..........so must be C.emiliae

But i see also on tibia 2 an pd or posterior seta and in the discription is standing ..female has strong ad....and no mention about pd or posterior.

Just save it for now as a C.emiliae.
Than forget the fly for 14 days (have fun, go out, drink wine, etc..:D:D)
And after 14 days just try again and maybe you will see the fly as new and see things you don't see right now!

Joke :)
