One more limp fly:o. I don't get what is happening with these flies.
What could it be? Maybe Fanniidae?
location: Barcelos, Portugal

Thanks Nikita;). What anthomyiid could this be?

Anthomyiid??? with such strong bent in M vein? Don't think so...

I don't think it's an Anthomyiid too. Possibly Rhinophoridae or whatever, I don't know...:)

Maybe i don't look right....but i don't see a bend of the M1, i only see the M1 stop suddenly...?
And am i right to say, there are only 3 dc..?
And lower calypter seems also a bit strange...almost like a Coenosia..?
Strange fly..!

it is very clear that M1 bend sharply in the first photo... (in the right wing). It seems it has no petiole.
The flash fade a lot the bent, though. Nevertheless there is a strong bend. Also check the second photo. The left wing shows also that bent! (not well visible but it is there!)
(also it miss 3 legs! Andrade is a torturer.)
Look at the very strong reclinate bristles. Doubt it is a muscid/anthomyiid.
It is really a very interesting species.

Then i vote for:
Calliphoridae
(maybe Melanomya nana....?)
Joke ...:S

yes, I thought it is a calliphorid. Concerning the species not sure. Maybe Stéphane knows this one.
Concerning the Melanomya nana: the M vein doesn't strong as sharply like this one; the wings are hyaline (and there is no any hint of infuscation)..

Joke is right, the vein M really stops suddenly, as you can see in the photo below. I think I can see 4 dc. Does anyone have more ideas of what species this could be?

strange! a trick of light!! or maybe it was a small thread doing a bent in the wing!!!
This photo shows without doubts that joke was right.

Ok...i do another try..
Presuming the M1 has no bend, what can we see more:
3 dorco centrals (i am still convinced there are three...see photo)
1 strong proclinate orbital
haltares yellow
2av +2-3 ad? + 2pd on tibia 3
1av+1ad+2pd? (ventral ?)
And face is protuding forward! (photo 2)
I think the lower calypter is to long for a Anthomyiidae
So could be a Muscidae
All Muscidae with a proclinate orbital who could be a possibility:
Drymeia = has 3 or more pd on t3, so does not fit
Hydrotaea = has 4 ore more dorso centrals, so does not fit
Potamia = has black haltares, so does not fit
Thricops = there are some species that could fit !
Thricops furcatus +
Thricops tatricus = has chaetotaxy on legs that could fit + 3dc + haltares yellow and Thicops has generally the face some protruding.
But.....i don't have species to compare with:(

Hi
This is Rhinophoridae, I'm almost certain of that.
Notice the rounded calypters diverging away from the longitudinal axis of the fly - not fool proof, but a good indication.
The only genus which lacks the bend in M is
Oplisa with four species. As for which species this one might belong to I haven't the faintest idea :|
Best regards,

Thank you Walther, I think the only known Iberian species is O. aterrima, could it be this one?

Joke, not sure, but I think that M1 doesn't end in the wing margin, you're pointing to what I believe is the other wing below. I'll try to collect some specimens to end the doubts:).

At first...I didn't know there where Rhinophoridae which lacks the bend in M !
And when you collect....save some for me :)

Yes, of course:).

I agree with Walter: this is Oplisa (Rhinophoridae). I recognize this genus always by the strong bristles at the ventral edge of the gena. Difficult, but visible on these pictures.
But only one of seven species described has vein M1 not ending at wing margin. An undescribed species has vein M1 transparent which may look as if M1 does not end at wing margin.
This is Oplisa aterrima. Next to vein M1 there are some other features of this species visible on these pictures: very strong bristle on basis of r4+5; strong bristles on subcosta of wing margin; large genital tergits and sternits.

Great!! Thank you very much Liekele!:D

Oplisa aterrima have returned! If you could confirm the specimens below in the photos belong to this species, I'll post them to the gallery. Joke, I've got some specimens for you.:)
Is the biology of the species known? Are they woodlouse parasitoids?

Hi Theo. Thanks, if you wish I can collect some specimens for you and send everything once. But only in some time will I be able to go to the site again, maybe only in two weeks' time.
