Brachypelma hamorii is a vulnerable species of tarantula found in Mexico. It has been confused with B. smithi; both have been called Mexican redknee tarantulas. Many earlier sources referring to B. smithi either do not distinguish between the two species or relate to B. hamorii. B. hamorii is a terrestrial tarantula native to the western faces of the Sierra Madre Occidental and Sierra Madre del Sur mountain ranges in the Mexican states of Colima, Jalisco, and Michoacán. The species is a large spider, adult females having a total body length over 50 mm (2 in) and males having legs up to 75 mm (3 in) long. Mexican redknee tarantulas are a popular choice for enthusiasts. Like most tarantulas, it has a long lifespan.
Cyriopagopus hainanus is a species of spider in the family Theraphosidae (tarantulas), found in China. It is one of a number of species from China and Vietnam known as "Chinese bird spider". It produces a venom containing numerous compounds capable of blocking neurotransmitters, including neurotoxic peptides called hainantoxins.
Cyriopagopus schmidti is a species of spider in the family Theraphosidae (tarantulas), found in China and Vietnam. It is one of a number of species known as "Chinese bird spider" and "Chinese earth tiger". Haplopelma huwenum was synonymized with this species in 2008. Spiders under this name and its synonyms have been shown to produce toxins called huwentoxins.
Sphodros is a genus of North American purseweb spiders first described by Charles Athanase Walckenaer in 1835. It was considered a synonym of Atypus until 1980.
Opisthothelae is a suborder of spiders within the order Araneae, containing Mygalomorphae and Araneomorphae, but excluding Mesothelae. The Opisthothelae are sometimes presented as an unranked clade and sometimes as a suborder of Araneae. In the latter case, Mygalomorphae and Araneomorphae are treated as infraorders.
Phidippus californicus is a species of jumping spider. It is found in the southwestern United States and northern Mexico.
Atypus karschi is a mygalomorph spider found in Korea, China, Taiwan, and Japan. It has been introduced into the United States. First described in 1887 by Friedrich Karl Wilhelm Dönitz, the specific name honors arachnologist Friedrich Karsch.
Porrhothele antipodiana, the black tunnelweb spider, is a species of mygalomorph spider that lives in New Zealand. It is the most common and widespread of several species in the genus Porrhothele, and is especially common in the greater Wellington region where the vagrant mature males are often encountered in or around dwellings. This species is one of New Zealand's most studied spiders. In New Zealand, the common name "tunnelweb spider" is also often used to refer to members of the genus Hexathele. Neither should be confused with their distant relatives, the highly venomous Australian funnel-web spiders.
Stanwellia grisea, also known as the Melbourne trapdoor spider, is a species of mygalomorph spider in the Pycnothelidae family. It is endemic to Australia. It was described in 1901 by British arachnologist Henry Roughton Hogg.
Hysterocrates gigas is a member of the tarantula family, Theraphosidae found in Cameroon. It is known as the giant baboon spider, Cameroon red baboon spider, or red baboon tarantula.
Hexathele hochstetteri, commonly known as the banded tunnelweb spider, is a spider in the family Hexathelidae, found only in New Zealand. It is common on the North Island, and uncommon on the South Island.
Pholcus phalangioides, commonly known as the cosmopolitan cellar spider, long-bodied cellar spider, or one of various types called a daddy long-legs spider, is a spider of the family Pholcidae. This is the only spider species described by the Swiss entomologist Johann Kaspar Füssli, who first recorded it in 1775. Its common name of "daddy long-legs" should not be confused with a different arachnid group with the same common name, the harvestman (Opiliones), or the crane flies of the superfamily Tipuloidea.
Sphodros niger, the black purse-web spider, is a mygalomorph spider from the Eastern United States. It is listed as a special concern species in Connecticut.
Zygoballus sexpunctatus is a species of jumping spider which occurs in the southeastern United States where it can be found in a variety of grassy habitats. Adult spiders measure between 3 and 4.5 mm in length. The cephalothorax and abdomen are bronze to black in color, with reddish brown or yellowish legs. The male has distinctive enlarged chelicerae and front femora. Like many jumping spiders, Z. sexpunctatus males exhibit ritualized courtship and agonistic behavior.
Spiders are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except Antarctica, and have become established in nearly every land habitat. As of September 2024, 52,309 spider species in 134 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900.
Sphodros atlanticus is a species of spiders from the family Atypidae. It was described by Willis J. Gertsch and Norman I. Platnick in 1980. The species was described from specimens found in Georgia, North Carolina, Virginia and Illinois. It has also been found in Maryland and Alabama.
Oxyopes lineatus is a species of spider in the family Oxyopidae, the so-called lynx spiders.
Atrax yorkmainorum is a venomous species of Australian funnel-web spider belonging to the Atracidae family and is found in forests in the vicinity of Canberra and south-eastern New South Wales. The genus Atrax was first documented in 1877 and the Atrax yorkmainorum species was first described in 2010.
Progradungula otwayensis, commonly known as the Otway odd-clawed spider, is a species of cribellate spider endemic to the Great Otway National Park of Victoria, Australia. It is one of only three species in the gradungulid genus Progradungula.
Eucteniza is a genus of trapdoor spiders in the family Euctenizidae containing at least 14 species occurring in Mexico and the southern United States. Species are distinguished by a softened rear portion of the carapace, and males possess large spines on the first two pairs of walking legs that are used to hold females during mating. Like other trapdoor spiders they create burrows with a hinged lid, from which they await passing insects and other arthropods to prey upon. Many species are known from only one or two localities, or from only male specimens. More species are expected to be discovered. Eucteniza is closely related to spiders of the genera Entychides and Neoapachella.
