Thread subject: :: Platystomatidae

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?

Hi Nikita,

The Platystomatidae do have a costal break (at humeral position), so I am afraid Shtakelberg is wrong in this case.
Just a quick glance at some pictures of wings of Calyptratae showed me that costal breaks are actually present. I suppose there are other members who can give you a more detailed answer on your Calyptratae question.

Hi Jan.
Today I was lucky to find one out of 3 part of Diptera volume of Insecta of Russian Far East. There is Platystomatidae in my part. There is C break in Platystomatidae.
Thank once more. Nikita
