Hedana is a genus of crab spiders that was first described by Ludwig Carl Christian Koch in 1874. [2]
As of September 2020 [update] it contains ten widely distributed species: [1]
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.
Uloborus is a spider genus in the family Uloboridae with 79 described species. Most species occur in the tropics and subtropics, with only a few species in northern America and Europe.
Diaea is a genus of crab spiders first described by Tamerlan Thorell in 1869. Most species are found in specific locations except for D. livens, which occurs in the United States and D. dorsata, which has a palearctic distribution. Adults are 5 millimetres (0.20 in) to 7 millimetres (0.28 in) and tend to hide in and around vegetation, especially flowers, where their color allows them to blend in to their surroundings.
Selenocosmia is a genus of tarantulas that was first described by Anton Ausserer in 1871. The genus is found in China, New Guinea, Australia, Indonesia, Myanmar, Malaysia, Laos, Vietnam, Philippines, India and Pakistan. They are commonly referred to as whistling or barking spiders, due to their ability to stridulate using lyra hairs.
Heteropoda is a genus of spiders in the family Sparassidae. They are mainly distributed in tropical Asia and Australia, while at least one species, H. venatoria, has a cosmopolitan distribution, and H. variegata occurs in the Mediterranean.
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.
Clubiona is a genus of sac spiders that was first described by Pierre André Latreille in 1804.
Runcinia is a genus of crab spiders that was first described by Eugène Louis Simon in 1875. The former R. elongata is a synonym of Thomisus elongatus.
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.
Cyrtarachne is a genus of orb-weaver spiders first described by Tamerlan Thorell in 1868.
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.
Cymbacha is a genus of crab spiders that was first described by Ludwig Carl Christian Koch in 1874.
Epidius is a genus of crab spiders that was first described by Tamerlan Thorell in 1877. It is a senior synonym of Pothaeus.
