Common Names: Amaurobiidae family
This is a catch-all for spiders in the Amaurobiidae family, which can be difficult to separate by only a photograph. They 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 Amaurobiidae family includes 286 species in 51 genera.
