Theo,
Again, I have a stupid question for you: what makes this Gymnosoma a nitens??? :|
Normally these species are very difficult to ID by photo and nitens is ID-able by some obscure structures on its femurs, which we can' t see here. B)
Groetjes!!!

That is easy: the wing venation is different.
Look at the stalk of the topcell.
Here, in nitens, it is pretty normal.
In all Other Gymnosoma, it is directly forwardly, giving it a peculiar angle with the vein r4+5.
Moreover, these types of concave triangles on tergites I have never seen in any other Gymnosoma.
