Indoor Blip: UK Visitor

Wavier and flaggier in large
Extra: Bath dancer

I found this speedy spider in the bathroom today; I think it is confused about where it is, because it isn't one of our local house spiders, but is one of the buzzing spider (/ghost spider) species that has recently made the UK home.
I suspect that this is Anyphaena numida, but I'm not certain, so have just tagged it Anyphaena sp.
