atleast you noticed that it looks different. I've seen it posted as Lucilia on sites and never changed.

Gymnocheta magna is similar but i think that it is restricted to peat bogs? I remember reading something about them last month. I just found one last month but i have yet to examine it. Anyway, there is a 99.9% chance that you have Gymnocheta viridis unless you found it at a peat bog.
