Dictis is a genus of spitting spiders that was first described by Ludwig Carl Christian Koch in 1872. [2]
As of January 2024 [update] it contains seven species, found in Asia, Oceania, North America and Seychelles: [1]
They are active hunters, and can be observed freely roaming in the foliage or on the forest floor. They prey on large ants and other spiders. [3]
Spitting spiders (Scytodidae) is a family of araneomorph spiders first described by John Blackwall in 1864. It contains over 250 species in five genera, of which Scytodes is the best-known.
Corinnidae is a family of araneomorph spiders, sometimes called corinnid sac spiders. The family, like other "clubionoid" families, has a confusing taxonomic history. Once it was a part of the large catch-all taxon Clubionidae, now very much smaller. The original members of the family are apparently similar only in that they have eight eyes arranged in two rows, conical anterior spinnerets that touch and are generally wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks.
Myrmarachne is a genus of ant-mimicking jumping spiders that was first described by W. S. MacLeay in 1839. They are commonly called ant-mimicking spiders, but they are not the only spiders that have this attribute. The name is a combination of Ancient Greek μύρμηξ, meaning "ant", and ἀράχνη, meaning "spider".
Cheiracanthium, commonly called yellow sac spiders, is a genus of araneomorph spiders in the family Cheiracanthiidae, and was first described by Carl Ludwig Koch in 1839. They are usually pale in colour, and have an abdomen that can range from yellow to beige. Both sexes range in size from 5 to 10 millimetres. They are unique among common house spiders because their tarsi do not point either outward, like members of Tegenaria, or inward, like members of Araneus), making them easier to identify.
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:
Clubiona is a genus of sac spiders that was first described by Pierre André Latreille in 1804.
Tetragnatha is a genus of long-jawed orb-weavers found all over the world. It was first described by Pierre André Latreille in 1804, and it contains hundreds of species. Most occur in the tropics and subtropics, and many can run over water. They are commonly called stretch spiders in reference to their elongated body form and their ability to hide on blades of grass or similar elongated substrates by stretching their front legs forward and the others behind them. The name Tetragnatha is derived from Greek, tetra- a numerical prefix referring to four and gnatha meaning "jaw". Evolution to cursorial behavior occurred long ago in a few different species, the most studied being those found on the Hawaiian islands. One of the biggest and most common species is T. extensa, which has a holarctic distribution. It can be found near lakes, river banks or swamps. Large numbers of individuals can often be found in reeds, tall grass, and around minor trees and shrubs.
Parasteatoda is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1946. The name is a combination of the Ancient Greek "para-" (παρά), meaning "near" or "next to", and the theridiid genus Steatoda. The Japanese name for this genus is O-himegumo zoku.
Mallinella is a genus of spider in the family Zodariidae.
Aphantaulax is a genus of ground spiders that was first described by Eugène Simon in 1878.
Jacaena is a genus of Asian liocranid sac spiders first described by Tamerlan Thorell in 1897.
Systaria is a genus of spiders in the family Miturgidae. It was first described in 1897 by Simon. As of 2018, it contains 26 species.
Teutamus is a genus of Southeast Asian liocranid sac spiders first described by Tamerlan Thorell in 1890.
Paramedmassa is a monotypic genus of Asian corinnid sac spiders containing the single species, Paramedmassa day. The genus was erected by C. Jin, H. L. Zhang, and F. Zhang in 2019 for a single species previously placed in Allomedmassa. The fourth section of the first legs can have anywhere from five to ten spines, depending on locale. Jin and Zhang propose that the morphological variance could indicate multiple species, but more individuals will need to be found and studied before a solid conclusion can be reached.
