The Purseweb spider (Atypus affinis) is a common mygalomorph spider from Europe, found mainly in southern England but ranging as far north as Southern Sweden and as far south as North Africa. It is the only British mygalomorph spider.

These spiders are black or brownish and not particularly large; the males are about 7-9mm while the females are larger at 10-15mm. They look much like Atypus piceus, but spiderlings are often very lightly colored, and the three-part posterior spinnerets do not have a light blot. Like other mygalomorph spiders, it has fangs that point straight down rather than crossing.

This spider spins an unusual web. It creates a tube of silk that is hidden partially underground, with the portion above ground being covered in leaves and other debris. The spider waits for an insect to land or crawl onto the tube, then bites through the silk to pull the insect inside. These spiders usually do not leave their webs for any reason other than mating.

These spiders become sexually mature at about four years. Autumn is the mating season, when the male spiders will seek out a female spider and enter her burrow where they live together until the male dies soon after mating. The female lays her egg sac inside the tube and the spiderlings hatch out the following summer, remaining with their mother for nearly another year after that.
