Hello piros,
it looks to me like some kind of Machimus species...

Daniel

Thank you! Yes, I agree, but I would like to know more, if possible...
Given the presence of strong bristles on ventral femur I, I thought about Machimus arthriticus, but it looks somewhat different, I think.

Regards,
Henrik

Still, M arthriticus is my best guess.

I would also guess that it is M arthriticus, although the epandrium looks a bit odd (maby it´s because of the angle). It was not too big right? below 2 cm?

Again, I agree with you, epandrium looks different from that of M. arthriticus. Also, this sp. is not known from the area, according to FE.

Yes, size is somewhat below 20mm, but not much, if I remember well.

Thank you for your continuing interest!

I would say that M arthriticus is correct, but i´m no expert though Wink
It is present in Bulgaria so i think it is not too far fetched to say that it could be distributed throughout greece

Thank you again, your opinion is encouraging Smile

(M. arthriticus is also known from the European part of Turkey, but nowhere else...)

I am pretty sure that this isn't M. arthriticus, the elongated 8th sternite excludes it. Not just the epandrium is not right for that species. The bristles on the ventral side of F1 is puzzling... I don't have an answer yet..

Dear Forum!
In April this year, I photographed several specimens of this sp. and managed to collect one male. Using both Engels key and a key found here:

https://docplayer.biz.tr/55195967-Orta-toros-daglari-nin-machimus-diptera-asilidae-cins-grubunun-sistematik-ve-faunistik-yonden-degerlendirilmesi-neslihan-alpay-aral.html

I arrived at Machimus annulipes. There is no doubt in my mind that this is the correct ID Smile, especially since the drawing of the hypopygium of M. annulipes in Engels matches that of the male I collected.

Indeed, there are several (4-5 in the case of females, 3 in males) black bristles on the ventral side of f1 among long, fine, yellowish hairs.

I attach the image of a female and its anterior leg below.

Thanks again to Daniel and Reinoud for their help!

You are very optimistic in believing that Mediterranean Machimus species can be identified beyond doubt from photographs. It is better to also collect specimens, especially males, and examine the genitals or gonostyli. Then you know more.

I collected a male and based the ID on the collected specimen.
But, of course, it is possible that I made a mistake
