Arrow-shaped Micrathena

I'm filming a band at a bar, just a different kind of animal :-)

Sometimes I am far away from being an expert ;-)...
Looking at your avatar I was wondering what you are looking into, I think it is not a microscope and I was wondering what the dark beer is doing there ;-)...

Thanks for that, I'm proving my none expert status.

Please, verify, most of this kind of spiders are not correctly IDed. Other candidate would be Micrathena sagittata, but I think it is Sexspinosa:
