Thank you for the answer. I rejected Keroplatidae because on my photo there are no crossveins visible. But I see that these are on some images not clearly visible. So now I think it fits well.
Not Platyura. In even in this image R4 ending in R1 should be visible and the petiole of the mdial fork seems to be too long for Platyura. No way to tell if the antennal segments are broadened in lateral view...
