Acantheis is a genus of Asian wandering spiders first described by Tamerlan Thorell in 1891. [2]
As of April 2019 [update] it contains nine species: [1]
Nursery web spiders (Pisauridae) is a family of araneomorph spiders first described by Eugène Simon in 1890. They resemble wolf spiders (Lycosidae) except for several key differences. Wolf spiders have two very prominent eyes in addition to the other six, while a nursery web spider's eyes are all about the same size. Additionally, female nursery web spiders carry their egg sacs with their jaws and pedipalps instead of attaching them to their spinnerets as wolf spiders do. When the eggs are about to hatch, a female spider builds a nursery "tent", places her egg sac inside, and stands guard outside, hence the family's common name. Like the wolf spiders, however, the nursery web spiders are roaming hunters that don't use webs for catching prey.
Liocranidae is a family of araneomorph spiders first described by Eugène Simon in 1897. They are one of several groups called "sac spiders". The holarctic genus Agroeca is the best-known, but it also includes various genera of more obscure spiders that still lack a diagnosis. Two species in the North American genus Neoanagraphis are found in the extremely dry conditions in the Mojave, Sonoran and Chihuahuan deserts. Females live in animal burrows while males wander and are the ones most often caught in pitfall traps.
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".
Colyttus is a genus of Asian jumping spiders that was first described by Tamerlan Thorell in 1891. C. lehtinen is named in honor of Finnish arachnologist Pekka T. Lehtinen.
Telamonia is a genus of jumping spiders that was first described by Tamerlan Thorell in 1887. They are colorful spiders, with patterns that vary considerably between sexes and species. Two longitudinal stripes along the abdomen are common, and the carapace is often colored. They have a slender opisthosoma and long legs.
Thiania is a genus of jumping spiders that was first described by Carl Ludwig Koch in 1846.
Selenocosmia is a genus of tarantulas that was first described by Anton Ausserer in 1871. The genus is found in China, New Guinea, Indonesia, 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.
Pacullidae is a family of araneomorph spiders first described by Eugène Simon in 1894. It was merged into Tetrablemmidae in 1958, then raised back to family status after a large phylogenetic study in 2017.
The Spartaeinae are a subfamily of the spider family Salticidae. The subfamily was established by Fred R. Wanless in 1984 to include the groups Boetheae, Cocaleae, Lineae, Codeteae and Cyrbeae, which in turn were defined by Eugène Simon.
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.
Matidia is a genus of southeast Asian sac spiders first described by Tamerlan Thorell in 1878.
Oedignatha is a genus of Asian spiders first described by Tamerlan Thorell in 1881 as a genus of corinnid sac spiders, and moved to Liocranidae in 2014.
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.
Epidius is a genus of crab spiders that was first described by Tamerlan Thorell in 1877. It is a senior synonym of Pothaeus.
Rhitymna is a genus of huntsman spiders described in 1897 by Eugène Simon. Members of this genus can be distinguished by a number of characteristics, but it is most often confused with Olios species, many of which also have the Y-shaped pattern on the dorsal opisthosoma.
Hygropoda is a genus of nursery web spiders that was first described by Tamerlan Thorell in 1894.
Omothymus is a genus of spiders in the family Theraphosidae, found in Malaysia, Indonesia and Singapore.
Cebrenninus is a genus of crab spiders that was first described by S. P. Benjamin in 2016. It is a senior synonym of Ascurisoma.
