Very well spotted !!!
It is the female of Gymnosoma costatum.

Please do collect in alkohol as in the previous case . I love to sample this one for DNA, if you agree. Many thanks !

Nice! No problem. You want them in separate vials?

By the way, you can see very small red lateral patches on the abdomen, also indicating this really is Gymnosoma and not Cistogaster.

Thanks Paul, interesting point

'Holding' might not be the perfect description. Apparently the armature makes contact with sensitive places on the female, coaxing her to agree to mate.

16.11.17 13:43
Is was not quite sure whether the word would apply correctly, but, yes, that is okay.

15.11.17 11:29
How about armature, would that fit? based on http://onlinelibra
ry.wiley.com/doi/1
0.1111/j.1365-3113
.2008.00422.x/pdf
it would seem that these spines etc are used to hold the female!

14.11.17 09:22
All spines, ridges, lobes, etc. on the femur.
