how do you measure it? do you have a specimen?

I do not think that it matches cingulata.
here is a valid cingulata (in my opinion according to Meigen 1820):

the yellow bands are very narrow before and after the very broad yellow band of t4.
the bands on the species in your photo are too broad.
it looks more like abbadon but I see no records for this in Slovenia.
