Macrobunus is a genus of tangled nest spiders first described by Albert Tullgren in 1901. [2]
As of April 2019 [update] it contains five species: [1]
Anyphaenidae is a family of araneomorph spiders, sometimes called anyphaenid sac spiders. They are distinguished from the sac spiders of the family Clubionidae and other spiders by having the abdominal spiracle placed one third to one half of the way anterior to the spinnerets toward the epigastric furrow on the underside of the abdomen. In most spiders the spiracle is just anterior to the spinnerets. Like clubionids, anyphaenids have eight eyes arranged in two rows, conical anterior spinnerets and are wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks. There are more than 600 species in over 50 genera worldwide.
Amaurobiidae is a family of three-clawed cribellate or ecribellate spiders found in crevices and hollows or under stones where they build retreats, and are often collected in pitfall traps. Unlidded burrows are sometimes quite obvious in crusty, loamy soil. They are 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, 2023, the family Amaurobiidae includes 286 species in 50 genera.
Sanogasta is a genus of South American anyphaenid sac spiders first described by Cândido Firmino de Mello-Leitão in 1941.
Laminacauda is a genus of dwarf spiders that was first described by Alfred Frank Millidge in 1985.
Hicanodon is a genus of South American tangled nest spiders containing the single species, Hicanodon cinerea. It was first described by Albert Tullgren in 1901, and has only been found in Chile and Argentina.
Aysenia is a genus of South American anyphaenid sac spiders first described by Albert Tullgren in 1902.
Ferrieria is a genus of South American anyphaenid sac spiders containing the single species, Ferrieria echinata. It was first described by Albert Tullgren in 1901, and has only been found in Chile and Argentina.
Negayan is a genus of South American anyphaenid sac spiders first described by M. J. Ramírez in 2003.

Allende is a genus of South American long-jawed orb-weavers that was first described by F. Álvarez-Padilla in 2007.
Selkirkiella is a genus of South American comb-footed spiders that was first described by Lucien Berland in 1924. Originally placed with the Araneidae, it was transferred to the comb-footed spiders in 1972.
