Argenna is a genus of cribellate araneomorph spiders in the Dictynidae family, and was first described by Tamerlan Thorell in 1870. [2]
As of May 2019 [update] it contains seven species: [1]
Dictynidae is a family of cribellate, hackled band-producing spiders first described by Octavius Pickard-Cambridge in 1871. Most build irregular webs on or near the ground, creating a tangle of silken fibers among several branches or stems of one plant.
Chalcoscirtus is a genus of jumping spiders that was first described by Philipp Bertkau in 1880. The name is derived from the Ancient Greek chalc-, meaning "copper", and scirt-, meaning "leap".
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.
Ozyptila is a genus of crab spiders that was first described by Eugène Louis Simon in 1864. It has been misspelled as "Oxyptila" in multiple accounts.
Neriene is a genus of sheet weavers that was first described by John Blackwall in 1833.
Clubiona is a genus of sac spiders that was first described by Pierre André Latreille in 1804.
Ceratinella is a genus of dwarf spiders that was first described by James Henry Emerton in 1882. They are very similar to both Ceraticelus and Idionella, and the taxonomy of these spiders may change.
Erigone is a genus of dwarf spiders that was first described by Jean Victoire Audouin in 1826. They are carnivorous, preying on small insects such as psylla and flies. One of the distinctive characters for this genus is the presence of teeth bordering the carapace.
Hypsosinga is a genus of orb-weaver spiders first described by Anton Ausserer in 1871. The genus name is derived from the Greek "hypso", meaning "high", referring to the higher clypeus than those of the genus Singa.
Dictyna is a genus of cribellate araneomorph spiders in the Dictynidae family, and was first described by Carl Jakob Sundevall in 1833.
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.
Agyneta is a genus of dwarf spiders that was first described by J. E. Hull in 1911.
Gibbaranea is a genus of orb-weaver spiders first described by Allan Frost Archer in 1951.
Micaria is a genus of ground spiders that was first described by Niklas Westring in 1851. They are 1.3 to 6.5 millimetres long.
Hilaira is a genus of dwarf spiders that was first described by Eugène Louis Simon in 1884.
Hypomma is a genus of dwarf spiders that was first described by David B. Hirst in 1886.
Collinsia is a genus of dwarf spiders that was first described by Octavius Pickard-Cambridge in 1913.
