This one looks very similar to the first - female Gymnosoma - long bare patch along the parafrontal and mainly dark tergites - I will stick my neck out a bit and go with Theo's G.costatum again :)

However, the black parafrontals are not elongated as in nudifrons. So this might key out to inornatum, a species with a pretty dubious species status.....

So, I'll keep my head and wo'n't stick out my neck.

Please, starting collecting this great material !

Hi Chris
Hi Theo

Thanks a lot again. I'll try to translate and understand the details as soon as possible.

If I'm understanding content right, this gymnosomas are special.
All shown Gymnosomas were really tiny and fast. Not easy to get them into focus - in warm sunshine they are very busy, they never rest for a while.

If I can find them next year again I'll try to collect . . . I'v no routine to do that. But I will try it.

Best regards, Brigitte

Hi Brigitte

If you need help with collecting procedures then just get in touch - I am happy to help :) It isn't usually difficult to catch a very useful series of specimens that can confirm beyond any doubt which species you are seeing :)
