Agyneta
dwarf spiders, sheet weavers
Agyneta is a genus of dwarf spiders (family Linyphiidae) containing over 200 species distributed across multiple continents. First described by J. E. Hull in 1911, these small sheet-weaving spiders are characterized by distinct genital structures used for species identification. The genus has been documented from Europe, South America, and other regions, with new species continuing to be described.
Ceratinopsis
Ceratinopsis is a genus of dwarf spiders (family Linyphiidae) containing approximately 44–46 accepted species. These spiders are small-bodied sheet-web weavers first described by James Henry Emerton in 1882. The genus belongs to the diverse assemblage of linyphiid spiders commonly known as money spiders or sheet-web weavers.
Goneatara
dwarf spiders
Goneatara is a genus of dwarf spiders in the family Linyphiidae, first described by S.C. Bishop and C.R. Crosby in 1935. The genus contains four recognized species, all endemic to the United States. These spiders are small-bodied members of the sheet-web weaving family, though specific ecological details remain poorly documented. The genus is rarely encountered in scientific literature beyond taxonomic descriptions.
Grammonota
Grammonota is a genus of dwarf spiders in the family Linyphiidae, first described by James Henry Emerton in 1882. The genus contains approximately 40-41 species distributed across the Americas, from Alaska in the north to Colombia in the south. Species occur in diverse habitats including the United States, Canada, Mexico, Central America, and the Caribbean. The genus is part of the sheet-web weaving spiders, though specific web-building behaviors vary among species.
Idionella
A genus of North American dwarf spiders (family Linyphiidae) comprising eight described species and one subspecies. First described by Nathan Banks in 1893, with members distributed across the United States and Mexico. The genus belongs to the sheet-web weaving spider family, though specific web architecture and behavioral details remain poorly documented.
Kaestneria
dwarf spiders
Kaestneria is a genus of dwarf spiders in the family Linyphiidae, first described by H. Wiehle in 1956. The genus contains eight species distributed across the Holarctic region and parts of Southeast Asia. Members are small-bodied spiders characteristic of the sheet-web building linyphiids.
Neriene
Neriene is a genus of sheet-web weaving spiders (family Linyphiidae) first described by John Blackwall in 1833. As of 2025, the genus contains approximately 62 species distributed across Africa, Asia, Europe, North America, and Greenland. These spiders construct distinctive sheet webs—horizontal platforms of silk often accompanied by a dome or bowl-shaped structure above. Species in this genus are small-bodied, with mature females typically measuring only a few millimeters. The genus has been subject to behavioral research, particularly regarding mating plug function in species such as N. emphana.
Tapinocyba
sheet weavers
Tapinocyba is a genus of sheet web spiders (family Linyphiidae) established by Eugène Louis Simon in 1884. The genus comprises approximately 40 species distributed across the Nearctic and Palearctic regions, including Europe, Asia, North America, and North Africa. Species are primarily found in leaf litter and forest floor habitats, often at montane elevations. Recent taxonomic work has clarified species boundaries and described new species from previously undersampled regions such as China and Nepal.
