Still no "Phaonia calcar" here. It looks like a female Mydaea, and in this case I would say Mydaea anicula (legs black, arista only short plumose, and palpi seems dilated). I'm not completely sure even of the genus because I can't manage to see whether the radial node (the place just before R2+3 and R4+5 fork) bears some setulae or not.

Hi Stephane, Thank you for the info. I don't think there are any setulae in that area, or they must be realy microscopic. There are some setulae at the base of the fork itself, as they are at some veins, but these are much smaller then the diameter of this veins. Anyway, this is all i manage to get out of the picture.

Setae have to be here. Sometimes in Mydaea is difficult to find these setae even under microscop, it helps that we deal with Diptera, not Monoptera

Thanks Klaas, indeed there is some setulae at radial node (see the annoted picture), so I think we can reasonably make a Mydaea anicula of it. It's true these setulae are difficult to see, but more easy to see when the veins are yellow (more difficult on Limnophora e.g.). Stephane Lebrun attached the following image:  [68.16Kb] Stephane. |
