The Amaurobiidae are three-clawed cribellate or ecribellate spiders found in most parts of the world and difficult to distinguish from related spiders in other families, especially Agelenidae, Desidae and Amphinectidae. Their intra- and interfamilial relationships are contentious. According to the World Spider Catalog, 2017, the family Amaurobiidae includes 286 species in 51 genera.
In Australia, they are small to medium-sized entelegyne spiders with generous sheet webs across the floor of rainforests. They generally have eight similar eyes in two conservatively curved rows. They often have a calamistrum on metatarsus IV associated with a cribellum. Australian amaurobiids may be distinguished from the Amphinectidae by the absence of a pretarsal fracture and the presence of a retrocoxal hymen on coxa I.
