Hi,


What do you think about this specimen caught in Camargue? (among some specimen of H bigoti) My hesitation is between ocelligera and subcylindrica

female pluvialis group for sure (in which your 2 hypothesis reside...at least in 1972Smile)

Doesn't have clear spots on tergites, therefore, does not look like ocelligera (there is a reason for this name !). Are you sure it is not bigoti ? Femur 2 looks pinkish, but very out of focus.

The third antennal segment will show orange on the inner side, the picture is simply dark and showing the other side. Clovis can check this.

Well, i'm getting a bit careful on the name of species! (look at Rhagio vitripennis) Smile

I'm not sure it's bigoti, as i don't have any specimen (Christoophe collected some specimens with me that turned out to be bigoti, i only caught this one)

But fémur 2 is as grey as the other femurs, and there is indeed some orange marking on antennal segment 3.

OK, thanks. If femur 2 is totally grey, also on the back side, than it cannot be bigoti. So it is either a no-greenish pluvialis (those exist, esp. in Eastern Europe) or subcylindrica. The first antennal segment does not support the latter view.

Yep, also on dorsal side.

So your vote is on pluvialis? (you wan't picture of something to support this opinion?)
Well, i wasn't lucky to catch the common one when Christoophe caught bigoti!

I think pluvialis is at this point the most likely.
