Hi, these big Phorids were all around, so I photographed 2 and collected other 2, but I think they are all the same. Some 5 mm long. They also invaded the car:) Mountain region.

So, I should brake off one wing, cook the animal in KOH, take one hind leg off, slide mount the animal laterally and the leg dorsoventrally?

Don't cook the wing ! Mounting the leg laterally is fine (it will lay that way naturally)...otherwise you've got it !

Not Hypocera. It is either a Triphleba or Diplonevra. A close up of the genitalia, not blocked by the legs, would let me be sure.

Hi, I cooked it in KOH and here are some details: Terminalia:

It is a male Triphleba. Good photos.

Thank You! How could we get a species id?

You'd have to use the key in Die Fliegen. Or send me the specimen and I'll identify it for you.

Thank You Brian. The preparated specimen luckily cleared out! It is beautiful, so many details :) Just for showing here are some pics:

Are there hairs on the vein before the fork ? If so, it is autumnalis. If not, it does not seem to correspond to anything in Disney...

Hi, I made two photos, which is the fork?

The fork is the V-configuration of veins in your first photo: look to see if there are hairs near this on the long vein...

Well, I only see those small microtrichia (?) which are present on the whole wing...

They would be long bristles if present - which seems not to be the case.

So, not autumnalis and not in the key of Disney... Interesting! Thank You for Your contribution!

You need to use Die Fliegen. Disney's book is only for England.

The first couplet in Die Fliegen is "scutellum with 4 large, subequal bristles" vs "anterior scutellar bristles much smaller than posterior" [actually, the literal translation is "scutellum four-bristled" versus "scutellum two-bristled", but you get the idea].

There are 49 species in Die Fliegen, and a few more have been described since.

Thank You Brian, I think I'll keep on catching them, making preparations, and ask for genus ID here, and later I will get in contact maybe with a local specialist, or get a copy of the Fliegen. There's a young entomologist in Hungary, who eorks with Papp, and he studies Phoridae, but I haven't got in contact with him yet.

Hi, I found this preparated fly from 2009 and made new photos of it with a better microscope.

These are the mouthparts:
