Ariamnes cylindrogaster is a spider belonging to the family Theridiidae. [1] It is found from Laos to Taiwan.
Like many species in its genus, A. cylindrogaster has an extremely elongated abdomen, resembling a twig or pine needle. Female body length is about 30 mm. Color ranges from green to brown. Males are slightly smaller (around 25 mm), but otherwise look similar. The abdomen can be bent upwards.
Ariamnes cylindrogaster hunts other spiders, using a simplistic web, which it constructs between trees. In Japan, almost 96% of its prey were found to be spiders in 24 species from 11 families.
The species creates an elongated egg sac.
Ariamnes cylindrogaster is found in Laos, China (including Hong Kong), Korea, Taiwan and Japan. It typically lives in forests.
Latrodectus is a broadly distributed genus of spiders with several species that are commonly known as the true widows. This group is composed of those often loosely called black widow spiders, brown widow spiders, and similar spiders. However, the diversity of species is much greater. A member of the family Theridiidae, this genus contains 34 species, which include several North American "black widows". Besides these, North America also has the red widow Latrodectus bishopi and the brown widow Latrodectus geometricus, which, in addition to North America, has a much wider geographic distribution. Elsewhere, others include the European black widow, the Australian redback spider and the closely related New Zealand katipō, several different species in Southern Africa that can be called button spiders, and the South American black-widow spiders. Species vary widely in size. In most cases, the females are dark-coloured and can be readily identified by reddish markings on the central underside (ventral) abdomen, which are often hourglass-shaped.
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world.
Theridiosoma is a genus of ray spiders that was first described by Octavius Pickard-Cambridge in 1879. They use their web as a high speed slingshot to actively hunt for prey.
The spider genus Steatoda, in the family Theridiidae, includes about 120 recognized species, distributed around the world. One common name is cupboard spider, for many species build their webs in dark, sheltered, undisturbed places around the house or garden, in sheds and garages, under garden, compost bins, and the like. Signs of the cupboard spider include small white spots of spider droppings, like small splashes of paint, on the floor underneath the web.
Steatoda grossa, commonly known as the cupboard spider, the dark comb-footed spider, the brown house spider, or the false widow or false black widow, is a common species of spider in the genus Steatoda.
The triangulate cobweb spider is a common spider in the genus Steatoda. It is well known for the triangle-shaped pattern on the dorsal side of its abdomen.
Argyrodes, also called dewdrop spiders, is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1864. They occur worldwide, and are best known for their kleptoparasitism. They can spin their own webs, but tend to invade and reside in their hosts' webs. This relationship can be commensal or even mutual if the dewdrop spider feeds on small trapped insects that are not eaten by the host. Some species can even prey upon the host.
Diguetia canities, commonly called the desert bush spider, is a species of coneweb spider found in desert and semidesert habitats in the United States from California eastward to Oklahoma and Texas.
Argyrodes flavescens, commonly called the red and silver dewdrop spider is a species of spider belonging to the family Theridiidae. It is widely distributed in Southeast Asia and is also found in Sri Lanka. Like other members of this genus, this species is a kleptoparasite, living on the web of a larger spider and feeding off its prey. A. flavescens most commonly inhabits the webs of araneids.
Parasteatoda is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1946. The name is a combination of the Ancient Greek "para-" (παρά), meaning "near" or "next to", and the theridiid genus Steatoda. The Japanese name for this genus is O-himegumo zoku.
Rugathodes sexpunctatus is a minute species of spider in the family Theridiidae, the cobweb or tangle-web spiders. This family includes the medically important genus Latrodectus—the widow spiders. The species in the genus Rugathodes are too small to be dangerous to humans. Very little is known about most species in this genus.
Steatoda bipunctata is a species of cob-web spider, of the genus Steatoda, in the family Theridiidae.
Spiders are air-breathing arthropods that have eight legs, 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 for Antarctica, and have become established in nearly every land habitat. As of November 2023, 51,673 spider species in 136 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.
Ariamnes colubrinus, known as the whip spider, is a common Australian spider belonging to the family Theridiidae. It is found in Victoria, New South Wales and Queensland.
Agelena labyrinthica is a species of spider in the family Agelenidae. It is a widespread species in Europe and its range extends to Central and East Asia.
Ariamnes uwepa is a species of spider from the family Theridiidae. It is only known to be found on Oahu, in the Hawaiian Islands. The name derives from the Hawaiian word "uwepa," meaning whip.
Ariamnes is a genus of comb-footed spiders that was first described by Tamerlan Thorell in 1869. Some species have greatly elongated abdomens, making them resemble a twig.
Ariamnes waikula is a species of spider from the family Theridiidae. The species is known only from the island of Hawaii, in the state of Hawaii. The type specimen was collected from wet forest habitat at 1,067 meters (3,501 ft) elevation. The species is named for its gold-colored abdomen using the Hawaiian word for gold-colored, "waikula." A scientific description of this species was first published in 2007 by Gillespie & Rivera.
Keijiella is a genus of spiders in the family Theridiidae. It was first described in 2016 by Yoshida. As of 2017, it contains only one species, Keijiella oculiprominens, found in "China, Taiwan, Laos, Korea, Japan".
Nesticus cellulanus, also known as the cavity spider or comb-footed cellar spider, is a species of scaffold web spider. It is found throughout Europe and Turkey, and has been introduced to North America.
