Uhmmm, I don't know!! This is a very interesting one!! I hope you collected this specimen!! If not, please go back to there and collect a few. Who knows, maybe Geomyza vikhrevi. Storage in alcohol might not be such a bat idea after all.

You certainly collect interesting material!

To collect it I had to stop myself on this two lower than medium quality photos.
One of a kind so far.

Hi Nikita,

Does this specimen have 1+2 dc or 1+3 dc? On the first picture it looks like ther are three post sutural dorsocentral bristles of which the first one is rather minute, but it is difficult to judge from your picture.

Jan Willem

---

It is the problem. My test - clearly 1+2. May be both dc of first postsutural pair are broken? Neither hypopleural seta. Arista long plumose dorsaly, very short ventraly. tp - darkened, ta - clear, but vein itself black.

---

Seems not to match any species I know (and I have seen most of the species described). I would love to have a look at this specimen!

Hi Jan.
I have news.
First fly was collected in 3-4m from my countryhouse. Taday I collected 3 more in 3 km from house under my "Medetera tree". 2 of them became to copulate inside my exgauster and did it according all Geomyza species I so far observed during good 60 min. So we have both sexes of same species at least.
I'll write again after I pin them and look under microscop.

Hi Nikita,

That's good news indeed. Having both sexes makes a positive identification easier. Please show pictures of the specimens once they have been pinned! I'm getting more and more curious.

First - one life photo, all three almost as small as first "G. apicalis" and obviosly larger that yesterday's Geomyza

---

Still I can't find 3-d pair of postsutural dc (or 3-d dc have to be almost as thin and short as ac).

---

Copulation inside my exgauster.
O, sorry, Black just has writen my that I have to use the word "aspirator".
In Deuchland - exgauster?

---

Your last pictures show very apicalis-like specimens. If you would examine the genitalia I expect these will lead you to G. apicalis. The wings of the specimen on your first picture are very wide for G. apicalis. However I would not be surprised if it turnes out to be conspecific with G. apicalis. It is a highly variable species (in colouration, size and width of the wings)! I have not seen apicalis specimens with wings as wide as in the specimen on your first pictures though.

For as far as I know exhauster and aspirator can both be used.

Non-entomological: well it's not my native language, yet I would still insist on 'aspirator', since it seems to me that 'exhauster' generally means a kind of a vacuum cleaner or similar gadget that is used 'for drawing out noxious air or waste material by means of a partial vacuum'.

---

Thank you Jan.
So 1+3. Well, apicalis isn't bad too.

...or just take the cheapest way out and call it a pooter. The aspirator I mean, not the fly. For a more formal word I'd side with Black, apirator sounds better than exhauster. If using an aspirator leaves you exhausted, I would recommend an immediate medical check

---

I would use pooter, as Kahis suggests, for all but the most formal discussion. Aspirator is better for very formal circumstances, as this implies air intake. Exhauster implies air expulsion so I think is not quite the right word. However, don't worry about it too much - I am sure everyone knew what you were talking about.

Thanks for you explanations Jere and Susan, although I went a little bit too linguistic
