Nesticus is a genus of American and Eurasian scaffold web spiders first described by Tamerlan Thorell in 1869. [3]
As of March 2022 [update] it contains the following species: [4]
Scaffold web spiders or cave cobweb spiders (Nesticidae) are a family of araneomorph spiders closely allied with tangle-web spiders (Theridiidae). Like the Theridiidae, these spiders have a comb of serrated bristles on the hind tarsi that are used to pull silk bands from the spinnerets. Nesticidae contains 16 genera and about 300 species, many of which are associated with caves or overhangs. The genus Nesticus is the type for the family and is found throughout the world. The related Eidmannella has speciated considerably in Texas caves and includes some extremely localized species that are considered threatened. One species, Eidmannella pallida, is found in caves and under overhangs, but also in agricultural fields and other habitats away from such restricted areas. The genus Carpathonesticus is found in central Eurasia.
Lycosa is a genus of wolf spiders distributed throughout most of the world. Sometimes called the "true tarantula", though not closely related to the spiders most commonly called tarantulas today, Lycosa spp. can be distinguished from common wolf spiders by their relatively large size. This genus includes the European Lycosa tarantula, which was once associated with tarantism, a dubious affliction whose symptoms included shaking, cold sweats, and a high fever, asserted to be curable only by the traditional tarantella dance. No scientific substantiation of that myth is known; the venom of Lycosa spiders is generally not harmful.
Nesticella is a genus of spiders of the family Nesticidae. Most of its species are found in Asia—from Russia to Japan, down to Indonesia and several other islands, including New Guinea—though some species from Africa and South-America are also known. It includes a blind spider, Nesticella marapu.
Pardosa is a large genus of wolf spiders, commonly known as the thin-legged wolf spiders. It was first described by C. L. Koch, in 1847, with more than 500 described species that are found in all regions of the world.
Hahnia is a genus of dwarf sheet spiders that was first described by C. L. Koch in 1841.
Centromerus is a genus of dwarf spiders that was first described by David B. Hirst in 1886.
