First, apologies for the quality.
Last year in May at the city borders of Vienna, I noticed an area where probably hundreds of Platystoma were sunbathing on poles and tree trunks - in numbers I have never experienced before. So I made wide-angle shots to show the number, without any close up photos and thus, the photos are heavily cropped.
I am still posting them here because I am now suspecting these not to be the common Platystoma seminationis (the only species currently known for the state), but another species. I think I can see reddish tarsi in some individuals and also the humeral calli seem to be light colored, so my suspicion would be *P. lugubris*, which seems also to be the most likely option when looking at the distribution.

But I don't necessarily want a species ID here, just a statement whether you agree that the general looks favors a different species.

Thanks a lot

P. lugubre has pinkish coloured humeral calli, all other species have humeral calli black. I cannot see it on your photos, so, which colour do you see?
