NOw that you mention it Phil, I went over some different pictures of the Wolf species and you can see a definite resemblance to the Wolf Spider, the Fangs and Venom sacks look pretty close but the striking feature I think was the front legs. The funnel webs seemed segmented more than the one shown where as the the Wolf dont seem to have these segments.
