Hello, this Tachinidae fly should be of the genus Carcelia. Do these photos allow us to identify it further?

Hello, I think female Carcelia is correct. But trying to use the T&H key is diffult with these 2 photos.
What I could find out:
basicosta yellow but mid tibia has 2 ad bristles with similar size
mid tibia is black?
abdomen has discals
arista is tapering more evenly
space between posterior ocelli not distinctly great
results in C. alpestris, which is only listed for northern Italy - and I couldn't find more details.
(C. kowarzi is a late and rare on in the pyrenees, but has yellow tibiae)

EDIT: The host of C. alpestris: Arctia flavia (Herting, 1966) is listed for the pyrenees (GBIF 43.2N, 3.0E) as is for the alps!
