Hi

* locality - Silgueiros - Viseu - PORTUGAL
* date - 2007.08.19
* size - 6 mm (medium fly)
* habitat - open land
* substrate - on Mentha sp. flowers.


This is Psycocephala sp.
Which one?


EDIT---> Title changed from "Conopidae - Psycocephala sp. which one?" to "Conopidae - Psycocephala chrysorrhoea" and then finally to "Conopidae - Psycocephala cf. lacera"

this seems to be no easy. Wink
I just know to say which is cannot be. P. nigra and P. rufipes are discarded.
But the problem is that I don?t know how is the degree of variation for these species. awkward

I have doubts in this one as well.
Now it seems for me to be a Conops. (seeing wing venation)
If this confirms, can this to be C. flavifrons?
Flavus is yellow in Latin. Yellow (totally) frons.

Hello Jorge,
on your first picture it looks like the animal has the silvery stripe on the side of the thorax, and that would make it Physocephala chrysorrhoea!
Greetings,

So I have 3 specimens of P. chrysorrhoea. Two small (about 6 mm - 7 mm) and one much more bigger one. Smile
All of them show some variation in the colour, specially in tergites.

This is again chrysorhoea.
The difference should be clear by now.

Jens-Hermann. Please provide the characters for P. lacera.. I have the specimen. It would be great to have final confirmation and the inevitable question... Why not P. chrysorrhoea?
