Advertisement I was wondering if anyone could help me identify these wonderful spiders. I'm pretty confident in my ability to identify a family, but could use some help otherwise in the Genus and if I'm lucky species aspect. They look to be Theridiidae and Thomisidae. I have a hunch that the Thomisidae is of the genus Xysticus, but could use some help clarifying. I haven't ever seen anything like the two Theridiidae before, so I don't know where to begin with those. Any help would be so much appreciated.
