Vienna, early April.
E. cyanicolor? Seems to have a blue shimmer, but also green present

I think you are right with female
E. cyanicolor - amongst others: "broad presutural midstripe whitish dusted" (Manual of Central European Muscidae).

I don't think the dusted stripe can be used to exclude the other two species - at least checking the gallery,
E. cyanella and
zimini also have this feature.

cyanella should not have a dusted
stripe prst and
zimini is closely related to
cyanella but bigger and there are differencies in bristles on mid tibia between
cyanella &
zimini. (again: MoCEM key by Gregor et al)

For clarification: is this supposed to be a distinction between a 'stripe' and an 'area'? Because, when looking at the photogallery here as well as on insecte.org, there is
[a] quite a variation among different individuals across the species, probably largely due to angle and lighting condition
[b] is whitish meant as 'lighter' or really white? Because in my specimen, the stringly dusted/white are is confined to the anterior region as well
[c)]
E. zimini fulfilling my definition of a prst dusted stripe
Not talking about other features, like chaetotaxy, here - just feel that in my opinion the mention in Gregor et al of the dusted stripe in one species only does not much help in species ID at best and might be misleading at worst

I'm sorry, but I have no other key for
Eudasyphora than Gregor, Rozkošný, Barták, Vaňhara.
I found 3 females and 1 male of
cyanicolor in 2020 and 2021 and one male of
cyanella in 2019 in my garden and took pictures from different angles.
The broad whitish (with changing density) midstrip is distinctly visible while
cyanella shows the 2 pairs of black prst stripes (and a whitish collar).
I did not find
E. zimini yet but the key says it's closely related to
cyanella...
And if we enlarge your first image I'm quite sure that the "Strong anterodorsal seta on mid tibia almost in the middle between strong posteroventral seta and apex of tibia" is visible.
And the eyes could be "almost bare".
