Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world.
Ground spiders comprise Gnaphosidae, the seventh largest spider family with nearly 2,000 described species in over 100 genera distributed worldwide. There are 105 species known to central Europe, and common genera include Gnaphosa, Drassodes, Micaria, Cesonia, Zelotes and many others. They are closely related to Clubionidae. At present, no ground spiders are known to be seriously venomous to humans.
Oonopidae, also known as goblin spiders, is a family of spiders consisting of over 1,600 described species in about 113 genera worldwide, with total species diversity estimated at 2000 to 2500 species. The type genus of the family is OonopsKeyserling, 1835.
Prodidominae is a spider subfamily, sometimes called long-spinneret ground spiders. It was formerly regarded as a separate family, Prodidomidae, which was reduced to a subfamily of the Gnaphosidae in 2018.
Anapidae is a family of rather small spiders with 231 described species in 58 genera. It includes the former family Micropholcommatidae as the subfamily Micropholcommatinae. Most species are less than 2 millimetres (0.079 in) long.
Mecysmaucheniidae is a family of araneomorph spiders first described by Eugène Simon in 1895. Most genera occur in South America, with two genera endemic to New Zealand.
Euophryini is a tribe of jumping spiders. It has also been treated as the subfamily Euophryinae.
Dolichognatha is a genus of tropical and subtropical long-jawed orb-weavers that was first described by Octavius Pickard-Cambridge in 1869. Originally placed with the Archaeidae, it was transferred to the Araneidae in 1967, and to the Tetragnathidae in 1981.
Coneweb spiders (Diguetidae) are six-eyed haplogyne spiders that live in tangled space webs, fashioning a cone-like central retreat where they hide and lay eggs. It is a small family, containing only two genera with fifteen species and is confined to the New World, preferring deserts. Members of the genus Diguetia usually build their webs in shrubs or between cactus pads. They have the same eye arrangement as the venomous recluse spiders, but none are known to be harmful to humans.
Cryptachaea is a genus of spiders in the Theridiidae family.
Dysderina is a genus of goblin spider.
Linyphia is a genus of dwarf spiders that was first described by Pierre André Latreille in 1804. The name is Greek, and means "thread-weaver" or "linen maker".
Synotaxus is a genus of araneomorph spiders in the family Synotaxidae that was first described by Eugène Louis Simon in 1895. Originally placed with the tangle web spiders, it was moved to the Synotaxidae in 2017.
Kwonkan is a genus of Australian tarantulas first described by Barbara York Main in 1983. It was originally assigned to Dipluridae, but was later assigned to Nemesiidae due to similarities to the genus Aname, before being transferred to the family Anamidae in 2010. Yilgarnia is now considered a synonym for this genus, and its type species is assigned to Kwonkan currycomboides.
Eilica is a genus of ground spiders that was first described by Eugen von Keyserling in 1891.
Liocranoides is a genus of American false wolf spiders that was first described by Eugen von Keyserling in 1881. They live in habitats with cold surfaces, such as caves. It was transferred from the sac spiders to the Tengellidae in 1967, which was later merged with Zoropsidae.
Physoglenidae is a family of araneomorph spiders first described by Alexander Petrunkevitch in 1928 as a subfamily of Pholcidae. It was later moved to Synotaxidae until a study in 2016 showed that they formed a distinct clade.
Trachelopachys is a genus of South American araneomorph spiders first described by Eugène Simon in 1897. Originally placed with the Corinnidae, it was moved to the Trachelidae in 2014.
