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.  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.
