Apparently, the colour characters are sometimes confusing in the repleta group - or the analysis is not 100 % certain? Not long ago I learnt that the dark rings on tibiae (not on tarsi) may be present in D. hydei (Diptera.info 27-09-2019 18:04). In the present specimens, molecular analysis shows that the costal darkening may not be quite certain character.
I determined thes specimens as "most probably repleta" also because repleta is a relatively common species, while mercatorum and buzzatii were not as yet known from well-studied Switzerland. But, with global warming and global exchange of goods, who knows? There are somewhat more than 100 known repleta-group species in the world (see taxodros. uzh.ch).
