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.
Cybaeidae is a family of spiders first described by Nathan Banks in 1892. The diving bell spider or water spider Argyroneta aquatica was previously included in this family, but is now in the family Dictynidae.
Austrochilidae is a small spider family with nine species in two genera. Austrochilus and Thaida are endemic to the Andean forest of central and southern Chile and adjacent Argentina.
The Entelegynae or entelegynes are a subgroup of araneomorph spiders, the largest of the two main groups into which the araneomorphs were traditionally divided. Females have a genital plate (epigynum) and a "flow through" fertilization system; males have complex palpal bulbs. Molecular phylogenetic studies have supported the monophyly of Entelegynae.
Coddingtonia is a genus of Asian ray spiders that was first described by J. A. Miller, C. E. Griswold, & C. M. Yin in 2009. It is a senior synonym of Luangnam.
Telema is a genus of long-legged cave spiders that was first described by Eugène Louis Simon in 1882.
Mysmena is a genus of spiders in the family Mysmenidae, found in many parts of the world.
Brasilionata is a genus of Brazilian spiders first described by Wunderlich in 1995. It is represented by a single species, B. arborense. The defining characteristics of this genus include a homogeneous color pattern on the back of the abdomen, setae on the cymbial fold the same size as other setae, a space between the anterior median eyes, and a pointed switch on the end of the palpal bulb similar to that of Microdipoena. Only two specimens have been identified, one in 1995 and another in 2015.
Negayan is a genus of South American anyphaenid sac spiders first described by M. J. Ramírez in 2003.
Austrochilus is a genus of South American cribellate araneomorph spiders in the family Austrochilidae, first described by H. Zapfe in 1955.
Olbus is a genus of South American corinnid sac spiders first described by Eugène Simon in 1880 as a huntsman spider. It was moved to the sac spider family in 1988, then to the Corinnidae in 2001.
Trogloneta is a genus of spurred orb-weavers that was first described by Eugène Louis Simon in 1922.
Synaphris is a genus of araneomorph spiders in the family Synaphridae, and was first described by Eugène Louis Simon in 1894. Originally placed with the tangle web spiders, it was moved to the Symphytognathidae in 1973, and to the Synaphridae in 2003.
Callitrichia is a genus of dwarf spiders that was first described by L. Fage in 1936.
Oedothorax is a genus of dwarf spiders that was first described by A. Förster & Philipp Bertkau in 1883.
Megaeupoa is a small genus of Asian jumping spiders first described by Y. J. Lin and S. Q. Li in 2020. It was not explicitly assigned to a position within the Salticidae, but the name Megaeupoa refers to the "evolutionary relationship" of the genus. As of March 2022 it contains only two species: M. gravelyi and M. yanfengi.
Notolinga is a monotypic genus of South American sheet weavers containing the single species, Notolinga fuegiana. It is a replacement name for Linga, already in use by a genus of molluscs. Eugène Simon described the first female in 1902 under the name "Neriene fuegiana", but the first male was not described until 2019. It has only been found in Argentina and on the Falkland Islands.
Tibetima is a small genus of east Asian palp-footed spiders. It was first described by Y. J. Lin and S. Q. Li in 2020, and it has only been found in China. As of March 2022 it contains only two species: T. char and T. gyirongensis.
