Thread subject: Diptera.info :: A muscid-like cyclorrhaphous fly
#1
This query is not really honest, because I know exactly WHAT IS THIS. But could you please tell me, what genus of muscids is this similar to?
#2
Well, an honestly dishonest query deserves an honest answer: I honestly do know squat about muscids, so I leave the glove to be picked up by someone else.

Such a large parafrontalia without interfrontalia I've seen in Sarcophagidae

Can we see more than the head ?
If not, please head in profile.

Theo: the rest is just a typical
Ulidia! That's the ansewer. It is an incredible thing how similar mating behavior leads to similarities in morphology, including almost holoptic male eyes, which are absolutely uncommon for acalyptrates at all (except perhaps ctenostylids).
Cheers,

Val,
the first photo shows clearly a white parafacialia, BUT in this last photo the colour of parafacialia is different. Image artefact? Or the specimen is another one?
That binocular loup/stereomicroscope shows chromatic aberration. We can see in the first photo along the inner margin of the left eye a cyan fringing. With an achromatic lens the problem would be solved.

Thanckxalot Jorge.
If U just knew what sort of junk was used to take this picture... Do U really believe that Santa lives in Ukraine? Unfortunately, I am a professional scientist, who have no additional income toupgrade a 30-years old microscope park at home. Furthermore, the blue/purple area simply is the part of the picture not treated for color balance in the Photoshop. On the contrary, the margins and setae were enhanced.
The parafacialium is, indeed, densely silvery-white microtrichose, and the microtrichia on the frons are directed laterally, so the reddish yellow cuticle is partly visible.

I can imagine...
Thanks for the explanation of the
parafacilium.
