Arachnida is a class of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons.
Amblypygi is an order of arachnid chelicerate arthropods also known as whip spiders or tailless whip scorpions. The name "amblypygid" means "blunt tail", a reference to a lack of the flagellum that is otherwise seen in whip scorpions. Amblypygids possess no silk glands or venomous fangs. They rarely bite if threatened, but can grab fingers with their pedipalps, resulting in thorn-like puncture injuries.
Wolf spiders are members of the family Lycosidae. They are robust and agile hunters with excellent eyesight. They live mostly in solitude, hunt alone, and usually do not spin webs. Some are opportunistic hunters, pouncing upon prey as they find it or chasing it over short distances; others wait for passing prey in or near the mouth of a burrow.
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.
The Pholcidae are a family of araneomorph spiders. The family contains more than 1,800 individual species of pholcids, including those commonly known as cellar spider, daddy long-legs spider, carpenter spider, daddy long-legger, vibrating spider, gyrating spider, long daddy, and skull spider. The family, first described by Carl Ludwig Koch in 1850, is divided into 94 genera.
Zoropsidae, also known as false wolf spiders for their physical similarity to wolf spiders, is a family of cribellate araneomorph spiders first described by Philipp Bertkau in 1882. They can be distinguished from wolf spiders by their two rows of eyes that are more equal in size than those of Lycosidae.
Dolomedes is a genus of large spiders of the family Pisauridae. They are also known as fishing spiders, raft spiders, dock spiders or wharf spiders. Almost all Dolomedes species are semiaquatic, with the exception of the tree-dwelling D. albineus of the southeastern United States. Many species have a striking pale stripe down each side of the body.
Plesiosiro is an extinct arachnid genus known exclusively from nine specimens from the Upper Carboniferous of Coseley, Staffordshire, United Kingdom. The genus is monotypic, represented only by the species Plesiosiro madeleyi described by Reginald Innes Pocock in his important 1911 monograph on British Carboniferous arachnids. It is the only known member of the order Haptopoda.
Maratus is a spider genus of the family Salticidae. These spiders are commonly referred to as peacock spiders due to the males' colorful and usually iridescent patterns on the upper surface of the abdomen often enhanced with lateral flaps or bristles, which they display during courtship. Females lack these bright colors, being cryptic in appearance. In at least one species, Maratus vespertilio, the expansion of the flaps also occurs during ritualised contests between males. The male display and courtship dance are complex, involving visual and vibratory signals.
Lamponidae is a family of spiders first described by Eugène Simon in 1893. It contains about 200 described species in 23 genera, most of which are endemic to Australia, with the genus Centrocalia endemic to New Caledonia, and two Lampona species also occurring in New Zealand where it is commonly known as the "White Tail" spider. Lampona papua is endemic to New Guinea, where two otherwise Australian species also occur.
Anapidae is a family of rather small spiders with 232 described species in 58 genera. It includes the former family Micropholcommatidae as the subfamily Micropholcommatinae, and the former family Holarchaeidae. Most species are less than 2 millimetres (0.079 in) long.
The caves of the Serro da Ramalho karst area in the municipality of Serra do Ramalho, a municipality of the same name in southwestern Bahia State, Brazil, have been explored since the early 2000s. The several large cave systems present a great biospeleological potential. Newly discovered species include the first troglobitic Amblypygi recorded for Brazil, Charinus troglobiusBaptista & Giupponi, 2003, an eyeless harvestman, an as yet undescribed genus of spiders (Ochyroceratidae), and a species of catfish.
Charinidae is an arachnid family within the order of tailless whip scorpions.
Charon is a genus of whip-spiders from Asia and Australasia, first described by Ferdinand Karsch in 1879.
Pinkfloydia is a genus of small Australian long-jawed orb-weavers, reaching a maximum lengths of about 4.5 millimetres (0.18 in). It was first described by D. Dimitrov & G. Hormiga in 2011, and contains two species, found in New South Wales and Western Australia: P. harveyi and P. rixi. They have a unique rounded, cone-shaped head structure with one pair of large eyes and three pairs of smaller eyes. The genus is named after British rock band Pink Floyd.
Alireza Zamani is an Iranian arachnologist and taxonomist.
Prionosternum is a genus of Australian white tailed spiders that was first described by R. A. Dunn in 1951. As of May 2019 it contains only three species: P. nitidiceps, P. porongurup, and P. scutatum. Originally placed with the ground spiders, it was moved to the Lamponidae in 2000.
Maratus pavonis is a species of jumping spider (Salticidae), endemic to Australia, where it is found in Western Australia, New South Wales, Victoria and Tasmania. The species epithet, pavonis, derives from the Latin, pavo, pavonis, meaning "peacock".
Charinus is a genus of amblypygids (whip-spiders) of the family Charinidae.
