Erigoninae are the largest subfamily of sheet weavers (Linyphiidae), which is itself the second largest spider family. In the United States they are known as dwarf spiders, while they are called money spiders in England. The exact taxonomic limits of the subfamily are not yet known.
Pimoidae is a small family of araneomorph spiders first described by J. Wunderlich in 1986. It contains 37 species in four genera and is monophyletic. It is closely related to the Linyphiidae, and is sometimes treated as synonymous with that family.
Pimoa is a genus of spiders in the family Pimoidae. Its sister genus is Nanoa.
Nanoa is a sister genus of Pimoa, in the spider family Pimoidae, containing the single species Nanoa enana.
Araneoidea is a taxon of araneomorph spiders, termed "araneoids", treated as a superfamily. As with many such groups, its circumscription has varied; in particular some families that had at one time moved to the Palpimanoidea have more recently been restored to Araneoidea. A 2014 treatment includes 18 families, with the araneoids making up about 26% of the total number of known spider species; a 2016 treatment includes essentially the same taxa, but now divided into 17 families.
Sinopimoa is a monotypic genus of Chinese sheet weavers containing the single species, Sinopimoa bicolor. It was first described by S. Q. Li & J. Wunderlich in 2008, and is found in China. It was originally placed in its own family (Sinopimoidae) but is now considered a member of the Linyphiidae, and it may be a member of the Erigoninae.
Pimoa cthulhu is a species of the spider family Pimoidae. It is one of twenty-one described species in the genus Pimoa.
Orsonwelles is a genus of American dwarf spiders that was first described by G. Hormiga in 2002. They are all native to the Hawaiian Islands, each species occurring on a single island, often at high elevations. One species has not been collected since the 1890s, and is believed to be extinct. The name honors the actor and film-maker Orson Welles. Many of the species names commemorate elements from Welles' films, radio productions, or roles.

Ophrynia is a genus of African dwarf spiders that was first described by R. Jocqué in 1981.
Ulugurella is a monotypic genus of Tanzanian sheet weavers containing the single species, Ulugurella longimana. It was first described by R. Jocqué & N. Scharff in 1986, and is only found in Tanzania.
Camafroneta is a genus of dwarf spiders containing the single species, Camafroneta oku. It was first described by H. Frick & N. Scharff in 2018, and is only found in Cameroon.
