Tidarren sisyphoides is a spider of the family Theridiidae (tangle web spiders).
Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs able to inject venom. 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 habitat with the exceptions of air and sea colonization. As of November 2015, at least 45,700 spider species, and 113 families have been recorded by taxonomists. However, there has been dissension within the scientific community as to how all these families should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.
Theridiidae is a large family of spiders, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders. Members of Theridiidae are the most common arthropods found in human dwellings throughout the world. The diverse, globally distributed family includes over 2,200 species in over 100 genera of three-dimensional space-web-builders. Theridiid spiders are entelegyne araneomorph ecribellate spiders that often build tangle space webs and have a comb of serrated bristles (setae) on the tarsus of the fourth leg.
The male of this species is only 1% the size of the female. At copulation, the male dies during insertion and remains attached to the female for more than two hours. However, the female does not eat her mate. The dead male is afterwards removed from the web.
From Sisyphos , a king in Greek mythology.
T. sisyphoides occurs from the southern United States to Colombia and on the West Indies.
Colombia, officially the Republic of Colombia, is a sovereign state largely situated in the northwest of South America, with territories in Central America. Colombia shares a border to the northwest with Panama, to the east with Venezuela and Brazil and to the south with Ecuador and Peru. It shares its maritime limits with Costa Rica, Nicaragua, Honduras, Jamaica, Haiti, and the Dominican Republic. Colombia is a unitary, constitutional republic comprising thirty-two departments, with the capital in Bogota.
The West Indies is a region of the North Atlantic Ocean in the Caribbean that includes the island countries and surrounding waters of three major archipelagos: the Greater Antilles, the Lesser Antilles and the Lucayan Archipelago.
Latrodectus is a broadly distributed genus of spiders, which is composed of both black widow spiders and brown widow spiders. A member of the Theridiidae family, this genus contains 31 species, including the North American black widows, the European black widow, the Australian redback black widow and the button spiders of Southern Africa. Species vary widely in size. In most cases, the females are dark-coloured and readily identifiable by reddish markings on the abdomen, which are often hourglass-shaped.
The redback spider, also known as the Australian black widow is a species of highly venomous spider believed to originate in the South Australian or adjacent Western Australian deserts, but now found throughout Australia, Southeast Asia and New Zealand, with colonies elsewhere outside Australia. It is a member of the cosmopolitan genus Latrodectus, the widow spiders. The adult female is easily recognised by her spherical black body with a prominent red stripe on the upper side of her abdomen and an hourglass-shaped red/orange streak on the underside. Females usually have a body length of about 10 millimetres (0.4 in), while the male is much smaller, being only 3–4 mm (0.12–0.16 in) long.
The katipo is an endangered species of spider native to New Zealand. It is one of many species in the genus Latrodectus, such as the Australian redback, and the North American black widows. The species is venomous to humans, capable of delivering a comparatively dangerous bite. The name katipo is from the Māori katipō, meaning "night-stinger". It is a small to medium-sized spider, with the female having a round black or brown pea-sized body. Red katipo females, found in the South Island and the lower half of the North Island, are always black, and their abdomen has a distinctive red stripe bordered in white. In black katipo females, found in the upper half of the North Island, this stripe is absent, pale, yellow, or replaced with cream-coloured blotches. These two forms were previously thought to be separate species. The male is much smaller than the female and quite different in appearance: white with black stripes and red diamond-shaped markings. Katipo are mainly found living in sand dunes close to the seashore. They are found throughout most of coastal New Zealand except the far south and west. Katipo feed mainly on ground dwelling insects, caught in an irregular tangled web spun amongst dune plants or other debris,
Steatoda grossa, commonly known as the cupboard spider, the dark comb-footed spider, the brown house spider, or the false black widow, is a common species of spider in the genus Steatoda.
Latrodectus pallidus is a species of spider commonly found throughout North Africa, the Middle East, and central Asia. A common name in English is the white widow spider, and it is known in Russian as белый каракурт, or white steppe spider. It is a member of the genus Latrodectus, which includes species known as widow spiders, which is placed in the Theridiidae family. It occurs both in the steppes of southern Russia, Kazakhstan, and other southwest Asian countries, as well as in the desert regions of the Middle East. Compared to other widow spiders in the region, the white widow spider is comparatively rare.
Latrodectus hesperus, the western black widow spider or western widow, is a venomous spider species found in western regions of North America. The female's body is 14–16 mm in length and is black, often with an hourglass-shaped red mark on the lower abdomen. This "hourglass" mark can be yellow, and on rare occasions, white. The male of the species is around half this length and generally a tan color with lighter striping on the abdomen. The population was previously described as a subspecies of Latrodectus mactans and it is closely related to the northern species Latrodectus variolus. The species, as with others of the genus, build irregular or "messy" webs: Unlike the spiral webs or the tunnel-shaped webs of other spiders, the strands of a Latrodectus web have no apparent organization.
Tidarren is a genus of spiders. The males are much smaller than females.
Theridion grallator, also known as the Hawaiian happy-face spider, is a spider in the family Theridiidae. Its Hawaiian name is nananana makakiʻi. The specific epithet grallator is Latin for "stilt walker", a reference to the species' long, spindly legs.
Nephilinae is a spider subfamily of the family Araneidae with five genera. The various genera in Nephilinae were formerly grouped in the family Nephilidae, and before that in the Tetragnathidae and in the Araneidae. All nephiline genera partially renew their webs.
Spider behavior refers to the range of behaviors and activities performed by spiders. Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms which is reflected in their large diversity of behavior.
Argyrodes argentatus is a kleptoparasitic spider.
Spider cannibalism is the act of a spider consuming all or part of another individual of the same species as food. In the majority of cases a female spider kills and eats a male one before, during, or after copulation. Cases in which males eat females are rare.
Sexual cannibalism is when a female cannibalizes her mate prior to, during, or after copulation. It is a phenomenon characterized primarily by members of most arachnid orders, as well as several insect orders. The adaptive foraging hypothesis, aggressive spillover hypothesis and mistaken identity hypothesis are among the proposed theories to explain how sexual cannibalism evolved. This behavior is believed to have evolved as a manifestation of sexual conflict, occurring when the reproductive interests of males and females differ. In many species that exhibit sexual cannibalism, the female consumes the male upon detection. Females of cannibalistic species are generally hostile and unwilling to mate; thus many males of these species have developed adaptive behaviors to counteract female aggression.
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.
Rugathodes sexpunctatus is a minute species of spider in the family Theridiidae, the cobweb or tangle-web spiders. This family includes the medically important Latrodectus genus—the widow spiders. The species in the Rugathodes genus are too small to be dangerous to humans. There is very little known about most species in this genus.
Tidarren argo is a spider from Yemen. The species is remarkable by its male amputating one of its palps before maturation and entering his adult life with one palp only. It adopts exceptional copulatory behaviour: when the male achieves genitalia coupling with his palp, the latter is torn off by the female. The separated gonopod remains attached to the female's epigynum for approximately 4 hours and continues to function independently, serving as a mating plug. While this happens, the female feeds on the male. Emasculation thus synchronizes sexual cannibalism and sperm transfer, lengthening the interval between copulations. This mating behaviour might allow for the continuation of insemination by the dismembered palp.
Argyrodes fissifrons is a species of spider of the genus Argyrodes. It is found in Sri Lanka to China and Australia.
Tidarren haemorrhoidale is a species of cobweb spider in the family Theridiidae. It is found in a range from the United States to Argentina.
