Hi,
Here is a male
Exorista from southern Brandenburg, seen on 31 July 2011. I’d vote for
E. grandis because of 4 postsutural dc, densely hairy eyes, and reddish scutellum. The second species with a comparable character set,
E. segregata, has not yet been recorded from Brandenburg. Do you agree?
Thanks, Sundew

Oh - and I was so happy that Moschweb
http://www.tachin...chweb.aspx led me directly to
Exorista... Obviously I lost
Phryxe when clicking "frontal setae, on parafacial, reaching the mid of the facial ridge" and "setae on facial ridge above vibrissa robust and more or less erect". However, comparing the excellent photo series of Steven Falk on
Exorista (
https://www.flick...234307197/) and
Phryxe (
https://www.flick...234296337/), I feel that Moschweb's alternatives are not entirely unambiguous...
The head profile of
Phryxe is obviously not as angular as that of
Exorista, it is more rounded and better matching my fly. So with the key
https://tachinida...igures.pdf I arrived at
P. vulgaris or
P. heraclei. I tend to the latter because it is rather dark and the dusting of the tergites is less extensive, but of course the name has to include a "cf."!
So thank you for pointing out further options.
