Atypidae, also known as atypical tarantulas or purseweb spiders, is a spider family containing only three genera. They are accomplished ambush predators that spend most of their time in a sock-like, silken retreat on the ground from where they kill their prey. [1]
Sphodros and Atypus occur in North America, while Atypus and Calommata occur in Asia and Africa. Only Atypus species are found in Europe. [2] Atypus affinis , Atypus muralis , and Atypus piceus are the only mygalomorph spiders found in Central Europe.
Atypus builds a silken tube parallel to the surface of the ground. While up to 8 cm of the tube lie on the ground, about 20 cm are buried vertically. The spider rests at the bottom of the tube. When prey walks on the exposed part, the spider, alerted by the vibrations, stabs the prey through the silk, cuts the web and drags the prey inside to be eaten. Calommata species, instead of building a purseweb, live in burrows. [3] Sphodros spp. usually prop their tubes against a tree trunk.
Atypical tarantulas have huge chelicerae for their size and relatively long spinnerets (although not as long as those found in diplurids). The males are sometimes brightly colored and wander around looking for females in their tubes. The females are reddish-brown or dark-colored.
During the breeding season for A. affinis, the male leaves his own burrow and goes in search of females. When he finds the burrow of a female, he tentatively taps on the wall of the purseweb, and if the female is receptive, he ventures into the confines of the burrow. The two spiders mate and cohabit until the male dies, when the female eats him. The female makes an egg sac and hangs it in her burrow. The next summer, the eggs hatch, and the spring after that, the spiderlings leave their mother's burrow and wander off to find a suitable place to build a lair of their own. [1]
Southeast Asian Atypus species have a body length of 7 to 21 mm in females, and about 12 mm in males. Calommata spp. of this region grow from 23 to 30 mm in females, and only about 7 mm in males. [3]
As of April 2019 [update] , the World Spider Catalog accepts the following genera: [2]
Wolf spiders are members of the family Lycosidae, named for their robust and agile hunting skills and 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. Wolf spiders resemble nursery web spiders, but wolf spiders carry their egg sacs by attaching them to their spinnerets, while the Pisauridae carry their egg sacs with their chelicerae and pedipalps. Two of the wolf spider's eight eyes are large and prominent; this distinguishes them from nursery web spiders, whose eyes are all of roughly equal size. This can also help distinguish them from the similar-looking grass spiders.
A tarantula hawk is a spider wasp (Pompilidae) that preys on tarantulas. Tarantula hawks belong to any of the many species in the genera Pepsis and Hemipepsis. They are one of the largest parasitoid wasps, using their sting to paralyze their prey before dragging it to a brood nest as living food; a single egg is laid on the prey, hatching to a larva which eats the still-living host. They are found on all continents other than Europe and Antarctica.
Wasps in the family Pompilidae are commonly called spider wasps, spider-hunting wasps, or pompilid wasps. The family is cosmopolitan, with some 5,000 species in six subfamilies. Nearly all species are solitary, and most capture and paralyze prey, though members of the subfamily Ceropalinae are kleptoparasites of other pompilids, or ectoparasitoids of living spiders.
Brachypelma is a genus of spiders in the family Theraphosidae (tarantulas). They may have bodies up to 6 cm long with legs of similar or greater lengths. Some species have brightly colored legs, with red or orange marks and rings.
Brachypelma smithi is a species of spider in the family Theraphosidae (tarantulas) native to Mexico. It has been confused with Brachypelma hamorii; both have been called Mexican redknee tarantulas. Mexican redknee tarantulas are a popular choice as pets among tarantula keepers. Many earlier sources referring to B. smithi either relate to B. hamorii or do not distinguish between the two species. B. smithi is a terrestrial tarantula native to Pacific coast of the Mexican state of Guerrero.
Lycosa tarantula is the species originally known as the tarantula, a name that nowadays in English commonly refers to spiders in another family entirely, the Theraphosidae. It now may be better called the tarantula wolf spider, being in the wolf spider family, the Lycosidae. L. tarantula is a large species found in southern Europe, especially in the Apulia region of Italy and near the city of Taranto, from which it gets its name.
Actinopodidae is a family of mygalomorph spiders found in mainland Australia and South America usually in open forest. Species are most common in Queensland, Australia. It includes mouse spiders, whose bites, though rare, are considered medically significant and potentially dangerous.
Atypus, also called purseweb spiders, is a genus of atypical tarantulas first described by Pierre André Latreille in 1804. It occurs in Eurasia, with one species reaching into North Africa. Only three of the described species occur in Europe: A. piceus, A. affinis, and A. muralis. Specimens from the USA formerly known as A. snetsingeri represent an introduced population of A. karschi.
Sphodros rufipes, sometimes called the red legged purseweb spider, is a mygalomorph spider from the southern and eastern United States, though it has been photographed as far north as Minnesota. It has confirmed sightings in Indiana, Missouri, New Jersey, West Virginia, Tennessee, Delaware, Louisiana, and Tuckernuck Island in Massachusetts. One recent sighting shows that these spiders can also be found in Canada, while another reveals that they've been spotted in Kansas.
Atypus affinis, the purseweb spider, is a mygalomorph spider from Europe and North Africa.
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.
Atypus piceus is a mygalomorph spider of the family Atypidae. It occurs in Europe to Moldavia and in Iran, and is the type species of the genus Atypus.
Chiasmocleis ventrimaculata, also known as the dotted humming frog, is a species of frog in the family Microhylidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. Its natural habitats are subtropical or tropical moist lowland forests, swamps, and intermittent freshwater marshes.
Tliltocatl albopilosus is a species of tarantula, also known as the curlyhair tarantula. The species' native range is Nicaragua and Costa Rica. They are largely terrestrial, opportunistically burrowing spiders.
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. As of December 2023, 1,100 species have been identified, with 166 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.
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.
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.
Aphonopelma iodius is a species of spider in the tarantula family Theraphosidae, found in United States. A 1997 paper combined it with three other previously described species into a single species, calling it "A. iodium". However, iodius is a neuter comparative adjective and is the correct form. Aphonopelma smithii has also been synonymized with A. iodius. A. iodius is common in the Mojave Desert to the west of the Colorado River.
Pepsis grossa is a very large species of pepsine spider wasp from the southern part of North America, south to northern South America. It preys on tarantula spiders, giving rise to the name tarantula hawk for the wasps in the genus Pepsis and the related Hemipepsis. Only the females hunt, so only they are capable of delivering a sting, which is considered the second most painful of any insect sting; scoring 4.0 on the Schmidt sting pain index compared to the bullet ant's 4.0+. It is the state insect of New Mexico. The colour morphs are the xanthic orange-winged form and the melanic black winged form. In northern South America, a third form, known as "lygamorphic", has a dark base to the wings which have dark amber median patches and a pale tip.
Qiongthela is a genus of spiders in the family Heptathelidae. As of 2021, it contains 14 species.
