Hi Dominique.
For information you can use my revision of Azelia, it is available here:
https://ia600308.us.archive.org/31/items/ReviewOfTheWorldFaunaOfTheGenusAzeliadipteraMuscidae/Amur15-1_Vikhrev.pdf
Several other species of Azelia have fore outer claw modified as on your photo, for example, A. beuki which I named in honour of foundator of diptera.info Dr. Paul Beuk :) But A. beuki is Oriental species connected with elephans which are absent in France. Your male has p seta on t1, this character it shares with A. parva and A. spinosa, but in both mentioned species fore outer claw is of normal size or almost so. Thus, your photos are A. monodactyla on my guaranteeŃ
