I'm making my database for Diptera families.
It is much more complicated task than I thought.
Could you help me with one of mysteries I found?
In Netherlands checklist Platystomatidae have "C only with humeral break". One the other hand according Shtakelberg only Acartophthalmidae have C only with humeral break. To Platystomatidae lead teza "C without break". Which source is right?

P.S. Another one related question, in case of Caliptrata, is there C break or not?
