Cyllognatha is a genus of comb-footed spiders that was first described by Ludwig Carl Christian Koch in 1872. [2]
As of May 2020 [update] it contains four species, found in Australia, Samoa, and India: [1]
Huntsman spiders, members of the family Sparassidae, are known by this name because of their speed and mode of hunting. They are also called giant crab spiders because of their size and appearance. Larger species sometimes are referred to as wood spiders, because of their preference for woody places. In southern Africa the genus Palystes are known as rain spiders or lizard-eating spiders. Commonly, they are confused with baboon spiders from the Mygalomorphae infraorder, which are not closely related.
Muziris is a genus of jumping spiders that was first described by Eugène Louis Simon in 1901. The name is derived from Muziris, a lost city in India.
Cryptothele is a spider genus with eight described species, now placed in the family Zodariidae.
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.
Argyrodes, also called dewdrop spiders, is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1864. They occur worldwide, and are best known for their kleptoparasitism. They can spin their own webs, but tend to invade and reside in their hosts' webs. This relationship can be commensal or even mutual if the dewdrop spider feeds on small trapped insects that are not eaten by the host. Some species can even prey upon the host.
Meta is a genus of long-jawed orb-weavers that was first described by Ludwig Carl Christian Koch in 1835. They are often associated with caves, caverns, and recesses, earning some of them the name "cave orbweavers"
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:
Cyrtophora, the tent-web spiders, is a genus of orb-weaver spiders first described by Eugène Simon in 1895. Although they are in the "orb weaver" family, they do not build orb webs. Their tent-like, highly complex non-sticky web is sometimes considered a precursor of the simplified orb web. These webs are aligned horizontally, with a network of supporting threads above them. These spiders often live in colonies. Females have a body length of mostly about 10 millimetres (0.39 in) long. Some members, including Cyrtophora cicatrosa, exhibit the ability to change colour rapidly.
Theridion is a genus of tangle-web spiders with a worldwide distribution. Notable species are the Hawaiian happy face spider (T. grallator), named for the iconic symbol on its abdomen, and T. nigroannulatum, one of few spider species that lives in social groups, attacking prey en masse to overwhelm them as a team.
Arachnura, also known as drag-tailed spider, scorpion-tailed spider and scorpion spider, is a genus of orb-weaver spiders that was first described by A. Vinson in 1863. They are distributed across Australasia, Southern and Eastern Asia with one species from Africa. Females can grow up to 1 to 3 centimetres long, while males reach only 2 millimetres (0.079 in) long. The name is a combination of the Ancient Greek "arachne-" (ἀράχνη) and "uro" (οὐρά), meaning "tail". The tails are only present on females, but unlike the common names suggests, these spiders aren't related to scorpions. They curl up their tails when disturbed, but they are completely harmless. Bites are rare, and result in minor symptoms such as local pain and swelling. They stay at the middle of their web day and night, and their bodies mimic plant litter, such as fallen flowers, twigs, or dead leaves.
Poecilopachys is a genus of Australasian orb-weaver spiders first described by Eugène Simon in 1895.
Larinia is a genus of orb-weaver spiders first described by Eugène Simon in 1874.
Desis is a genus of intertidal spiders that was first described by Charles Athanase Walckenaer in 1837. Species of the genus are found in Australasia, the Pacific, Japan, eastern and southern Africa, and India. They are marine spiders, living in the intertidal zone and only emerging at the ebb tide to hunt for invertebrates including shrimp. When submerged during high tides, they stay in an air chamber sealed with silk, and breathe its air.
Poltys is a genus of orb-weaver spiders first described by C. L. Koch in 1843. Many species are cryptic and are known to masquerade as leaves and twigs during the day, and build an orb web at night to capture prey. The shape of the abdomen which often gives the impression of a rough and broken branch can vary among individuals within a species. The web is eaten up before dawn and reconstructed after dusk.
Phoroncidia is a genus of comb-footed spiders that was first described by J. O. Westwood in 1835.
Arkyidae, also known as triangular spiders, is a family of araneomorph spiders first described by Ludwig Carl Christian Koch in 1872 as a subfamily of Araneidae, and later elevated to a full family in 2017.
Dictis is a genus of spitting spiders that was first described by Ludwig Carl Christian Koch in 1872.
Rhomphaea is a genus of comb-footed spiders that was first described by Ludwig Carl Christian Koch in 1872.
