The wing venation is odd.
I'm not even sure it is Cylindromyia.

What a strange fly ... related to
Cylindromyia, but that petiole is very unusual :o The artista is very odd too... I have no idea what it could be if it isn't
Cylindromyia :(

Thank you guys! when I saw the fly on the photos I instantaneously noticed the strange petiole. If it's not a Cylindromyia what could it be:o? Now I'm very curious about it.

Cylindromyia has 2 rather typical features
* palpi absent
* behind coxae complete chitinised bridge
So if it was collected....
Any indication of its size ?

Yes, I collected the fly. The size is about 6 mm.
Some photos:

I can't see palps but they might just be very small - needs putting on a pin (never manipulate a specimen without mounting it first) and then looking at under a microscope. The bridge on the hind coxae is only visible with a ventral angle - and a little posterior too. :)

STOP
Look at the arista: it is distinctly broadened towards the tip.
That settles it inmediately:
Male Cylindromyia pusilla.
The 6 mm. supports this.
I had guessed it was more like 12 mm.
Therefore I did not consider pusilla.
Yet another succesful ID with Rui's help
