Scutellar bristles are wrong for Campylocheta.

 The right ocellar is reclinate in some pictures, but seems proclinate in the last. Difficult to see !

 Does Campylocheta (also observed in vicinity: https://www.inatu...s/70318730 ) have a petiole at r4+5 ?

 No, of course not ! So you are right. Antenna is pretty long in Chaetogena tschorsnigi.
Based on abdominal pattern and reddish apex to scutellum, this is the male of tschorsnigi.

It is peculiar that fasciata, the 'original' species, is hardly ever more reported.

I will try to fix the messages this month. We have to make some other configuration changes before software goes out of support at end of year.
