Berlin - mid August - 6.5 mm Female

I could be wrong but I suspect this to be Helina. I have no keys to this genus. I would like to have a copy of The Muscidae of Central Europe. Meantime, I see four dots on the abdomen, so Helina quadrinotata?

PS the ovipositor (genitalia) is better than counting hairs. just ask and I'll post the ovipositor.

I have found some keys from a book at Google Books. I only get a few pages of a preview. I have to apologize for my inadequate post. I see that we will need many photos of this species to be able to determine a species.

I will update this post with more adequate details. I think that we can eliminate quadrinotata. I am suspecting Helina parcepilosa is a possibility.

I will add more photos...

No need to apologize. It's true Helina are difficult from picture since some details can't usually be seen (like setulae on ventral side of radial node, beneath scutellum etc).
If the arista is plumose, I would tend to say H. parcepillosa as well (I guess 4 ks).
Stephane.

Hello Sir Stephane, Thank You for your Time and Expertise. I didn't realize how difficult it is to id Helina. I am sorry about my sloppy post.

I've spent some time at the microscope today. I'll post some photos now.

first photo is of the underside of the scutellum:

eyes are sparsely hairy, so I suppose bare fits as well.

palpi are black. The tiip of the palpi seems pale in certain angles with strong lighting.

here is a better view of the ovipositor.
I find it difficult to deal with an ovipositor. sometimes my dissection is awful. I broke the end off from the ovipositor. sorry. I teach myself how to dissect, so I am not familiar with a proper procedure. at least I have photos of it Smile

these are a dorsal view of the oviposior from the en of the abdomen to the tip of the ovipositor (3 photos) plus spermathecae:
