Socalchemmis dolichopus is a species of araneomorphae spider of the family Zoropsidae. [1]
The species is endemic to California in the United States. [2] It is found in the counties of Los Angeles, Orange, Riverside and San Bernardino.
The male described by Platnick and Ubick in 2001 measured 8.1 millimetres (0.32 in) and the female was 7.5 millimetres (0.30 in). [2]
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.
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.
Tengellidae is a former family of spiders that has been merged into the family Zoropsidae. Genera formerly placed in Tengellidae now in Zoropsidae include:
Amaurobiidae is a family of three-clawed cribellate or ecribellate spiders found in crevices and hollows or under stones where they build retreats, and are often collected in pitfall traps. Unlidded burrows are sometimes quite obvious in crusty, loamy soil. They are difficult to distinguish from related spiders in other families, especially Agelenidae, Desidae and Amphinectidae. Their intra- and interfamilial relationships are contentious. According to the World Spider Catalog, 2023, the family Amaurobiidae includes 286 species in 50 genera.
Zoropsidae, also known as false wolf spiders for their physical similarity to wolf spiders, is a family of cribellate araneomorph spiders first described by Philipp Bertkau in 1882. They can be distinguished from wolf spiders by their two rows of eyes that are more equal in size than those of Lycosidae.
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.
Myrmekiaphila is a genus of North American mygalomorph trapdoor spiders in the family Euctenizidae, and was first described by G. F. Atkinson in 1886. All described species are endemic to the southeastern United States.
Caponiidae is a family of ecribellate haplogyne spiders that are unusual in a number of ways. They differ from other spiders in lacking book lungs and having the posterior median spinnerets anteriorly displaced to form a transverse row with the anterior lateral spinnerets. Most species have only two eyes, which is also unusual among spiders. A few species of Caponiidae variously have four, six or eight eyes. In some species the number of eyes will increase when the spiderling changes its skin as it grows towards adulthood.
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.
Orthonops is a genus of North American araneomorph spiders in the family Caponiidae, first described by R. V. Chamberlin in 1924.
Titiotus is a genus of American false wolf spiders that was first described by Eugène Louis Simon in 1897.
Sergiolus is a genus of ground spiders that was first described by Eugène Simon in 1892. They are 3.3 to 9 millimetres long.
Sosticus is a genus of ground spiders that was first described by R. V. Chamberlin in 1922.
Oaphantes is a genus of North American dwarf spiders that was first described by Ralph Vary Chamberlin & Vaine Wilton Ivie in 1943.
Anachemmis is a genus of North American false wolf spiders that was first described by Ralph Vary Chamberlin in 1919. It was briefly synonymized with Titiotus, but was reconfirmed as its own distinct genus in 1999.
Socalchemmis is a genus of North American false wolf spiders that was first described by Norman I. Platnick & D. Ubick in 2001. The genus name comes from a shortening of the phrase "Southern Californian Chemmis", as the genus was discovered in California.
Anachemmis sober is a species of false wolf spiders & wandering spiders in the family Zoropsidae. It is found in the United States, specifically southern California, in primarily oak forests.
Drassinella is a genus of North American araneomorph spiders in the family Phrurolithidae, first described by Nathan Banks in 1904.
Cinetomorpha is a genus of goblin spiders first described by Eugène Louis Simon in 1892. It is a senior synonym of Lucetia, and Yumates.
