The Araneomorphae are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae, where they point straight down. Araneomorphs comprise the vast majority of living spiders.
Deinopidae, also known as net casting spiders, is a family of cribellate spiders first described by Carl Ludwig Koch in 1850. It consists of stick-like elongated spiders that catch prey by stretching a web across their front legs before propelling themselves forward. These unusual webs will stretch two or three times their relaxed size, entangling any prey that touch them. The posterior median eyes have excellent night vision, allowing them to cast nets accurately in low-light conditions. These eyes are larger than the others, and sometimes makes these spiders appear to only have two eyes. Ogre-faced spiders (Deinopis) are the best known genus in this family. The name refers to the perceived physical similarity to the mythological creature of the same name. This family also includes the humped-back spiders (Menneus).
Gilles De Bilde is a Belgian former professional footballer, sports pundit and television personality.
Theraphosa is a genus of South American tarantulas that was first described by Charles Athanase Walckenaer in 1805. The Theraphosa spiders are some of the largest known to science. As of May 2020 it contains three species, found in Guyana, Brazil, Venezuela, and Colombia. They stridulate by rubbing setae on their pedipalps and legs.
Prodidomidae is a family of spider, sometimes called long-spinneret ground spiders. It was formerly regarded as a subfamily of Gnaphosidae, but was raised to a family in 2022.
The Halidae were a tiny spider family with only three described species in two genera. As of 2006, this family was no longer considered valid; the two genera are instead grouped in the family Pisauridae.
A social spider is a spider species whose individuals form relatively long-lasting aggregations. Whereas most spiders are solitary and even aggressive toward other members of their own species, some hundreds of species in several families show a tendency to live in groups, often referred to as colonies.
Eurypteroidea are an extinct superfamily of eurypterids. It contains three families and two genera of uncertain classification, Paraeurypterus and Pentlandopterus.
Chikunia nigra is a species of spider of the genus Chikunia. It is found in Sri Lanka to Taiwan, and Indonesia.
Xenesthis is a genus of tarantulas that was first described by Eugène Louis Simon in 1891. As of May 2020 it contains four species, found in Colombia and Venezuela, though it was previously considered to be found in Panama.
Omothymus is a genus of spiders in the family Theraphosidae, found in Malaysia, Indonesia and Singapore.
Manzuma nigritibiis is a species of jumping spider in the family Salticidae. It is found in Ethiopia and Yemen.
Diploperculata is an infraorder of eurypterids, an extinct group of aquatic arthropods commonly known as "sea scorpions". The name, derived from Greek διπλόω ("double") and operculum, refers to the distinguishing feature that unites the superfamilies included in the group, that the genital operculum is made up of two fused segments.
Onychopterellidae are an extinct family of eurypterids. The family is the only family classified as part of the superfamily Onychopterelloidea. Genera included are Alkenopterus, Onychopterella and Tylopterella.
Moselopteridae are an extinct family of eurypterids. It is the only family classified as part of the superfamily Moselopteroidea, and contains three genera: Moselopterus, Stoermeropterus and Vinetopterus.
The Selenocosmiinae are a subfamily of tarantulas found throughout South-East Asia and Australia. This subfamily is defined by the presence of a lyra on the maxillae and strikers on the chelicerae, allowing these spiders to stridulate and produce a "hissing" sound. However some species within Phlogiellus may have secondary lost their lyra but retain their strikers. The monophyly of the subfamily has been only tested using genetic data with a handful of genera or species in a few studies. However, these studies found genera that had been previously placed in this subfamily were actual their own separate subfamily (Poecilotheria) and that Selenocosmiinae is most closely related to the Indian Thrigmopoeinae. As of 2021, Selenocosmiinae contains 11 genera.
Chikunia albipes is a species of comb-footed spider in the family Theridiidae. It is found in Russia, China, Korea, and Japan.
Micythus anopsis is a species of ground spider found in Thailand. It is the most recent species of Micythus to be discovered.
Yuri Mikhailovitch Marusik is a Russian arachnologist.
Trachycosmidae, is a family of spiders in the infraorder Araneomorphae.
