Nodocion is a genus of ground spiders that was first described by R. V. Chamberlin in 1922. [3]
As of May 2019 [update] it contains eight species: [1]
Ground spiders comprise Gnaphosidae, the seventh largest spider family with over 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.
Benoy Krishna Tikader (1928–1994) was an Indian arachnologist and zoologist and a leading expert on Indian spiders in his time. He worked in the Zoological Survey of India and published the Handbook of Indian Spiders in 1987. The book describes 40 families and 1066 species of India, many of which were described by Tikader himself. The handbook is a guide to all arachnids including scorpions, and not just spiders. He was also a popular scientific author in his native language of Bengali, and was the author of Banglar Makorsha for the layman.
Xysticus is a genus of ground crab spiders described by C. L. Koch in 1835, belonging to the order Araneae, family Thomisidae. The genus name is derived from the Ancient Greek root xyst, meaning "scraped, scraper".
Phidippus is a genus in the family Salticidae. Some of the largest jumping spiders inhabit this genus, and many species are characterized by their brilliant, iridescent green chelicerae. Phidippus is distributed almost exclusively in North America, with the exception of two exported species. As of January 2021, there were about 80 described species in the genus. Species previously described in Phidippus which are found in India and Bangladesh do not belong in this genus.
Drassodes is a genus of ground spiders that was first described by Niklas Westring in 1851. They are brown, gray, and red spiders that live under rocks or bark in mostly dry habitats, and are generally 3.8 to 11.6 millimetres long, but can reach up to 20 millimetres (0.79 in) in length.
Castianeira is a genus of ant-like corinnid sac spiders first described by Eugen von Keyserling in 1879. They are found in Eurasia, Africa, and the Americas, but are absent from Australia. Twenty-six species are native to North America, and at least twice as many are native to Mexico and Central America.
Neoscona, known as spotted orb-weavers and barn spiders, is a genus of orb-weaver spiders (Araneidae) first described by Eugène Simon in 1895 to separate these from other araneids in the now obsolete genus Epeira. The name Neoscona was derived from the Greek νέω, meaning "spin", and σχοῖνος, meaning "reed" They have a mostly pantropical distribution and one species, Neoscona adianta, has a palearctic distribution. As of April 2019 there are eight species that can be found in the United States and Canada:
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.
Callilepis is a genus of ground spiders first described by Niklas Westring in 1874. Some are found from Mexico to Canada, others from Europe to India. They are most commonly found in dry areas, sandy roads and beaches.
Zelotes is a genus of ground spiders that was first described by J. Gistel in 1848.
Gnaphosa is a genus of ground spiders that was first described by Pierre André Latreille in 1804. They all have a serrated keel on the retromargin of each chelicera.
Herpyllus is a genus of ground spiders first described by Nicholas Marcellus Hentz in 1832.
Drassyllus is a genus of ground spiders that was first described by R. V. Chamberlin in 1922.
Haplodrassus is a genus of ground spiders that was first described by R. V. Chamberlin in 1922. They range from 3 to 10 millimetres. H. signifer is the most widespread species, found across North America except for Alaska and northern Canada.
Litopyllus is a genus of ground spiders that was first described by R. V. Chamberlin in 1922. As of May 2019 it contains only three species: L. cubanus, L. realisticus, and L. temporarius.
Orodrassus is a genus of North American ground spiders that was first described by R. V. Chamberlin in 1922. As of May 2019 it contains only three species: O. assimilis, O. canadensis, and O. coloradensis.
Sosticus is a genus of ground spiders that was first described by R. V. Chamberlin in 1922.
Talanites is a genus of ground spiders that was first described by Eugène Simon in 1893.
