Cyrtarachninae
Cyrtarachninae is a subfamily of spiders in the family Araneidae (orb-weaver spiders, araneids). The group has been circumscribed in several different ways. It originated as the group Cyrtarachneae, described by Eugène Simon in 1892. The group was later treated at different ranks: as a tribe, both under Simon's name and as Cyrtarachnini, and as the subfamily Cyrtarachninae. Circumscriptions have varied. The broadest circumscription, Cyrtarachninae ''sensu lato'' (''s.l.''), includes three of Simon's original groups, including the bolas spiders (also placed in the tribe Mastophoreae or Mastophorini, or in the subfamily Mastophorinae). Unlike most araneids, members of the subfamily do not construct orb webs, some not using webs at all to capture prey, some using one or more sticky drops on a single line (a bolas), while others construct webs with few widely spaced non-spiral threads, some triangular. Many have been shown to attract prey by producing analogues of insect sex pheromon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolas Spider
A bolas spider is a member of the orb-weaver spider (family Araneidae) that, instead of spinning a typical orb web, hunts by using one or more sticky "capture blobs" on the end of a silk line, known as a "bolas". By swinging the bolas at flying male moths or moth flies nearby, the spider may snag its prey rather like a fisherman snagging a fish on a hook. Because of this, they are also called angling or fishing spiders (although the remotely related genus ''Dolomedes'' is also called a fishing spider). The prey is lured to the spider by the production of up to three sex pheromone-analogues. Bolas spiders have been treated as either the whole or part of either the tribe "Mastophoreae" or Mastophorini, the subfamily Mastophorinae, or the informal group mastophorines. Recent studies show that the genus ''Celaenia'', which does not use a bolas, belongs in the same taxonomic group. Description Bolas spiders are small nocturnal animals with conspicuous outgrowths on the upper (dorsa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mastophora Extraordinaria
''Mastophora extraordinaria'' is a species of spider in the orb-weaver spider family Araneidae. It is found in South America (Brazil, Uruguay and Argentina). Like some other species of the genus '' Mastophora'', adult females resemble bird droppings. ''Mastophora'' species, including ''M. extraordinaria'', are "bolas spiders" – adult females capture their prey by using a sticky drop on the end of a single line which they swing at the target, usually a male moth attracted by the release of an analogue of the attractant sex pheromone produced by the female moth. Juveniles and adult males do not use a bolas, catching prey with their legs alone. Description Herbert W. Levi described a female in 2003 (males were not known). The total length of the specimen's body was . Other females ranged from . The carapace was long and almost as wide in the thoracic region. The carapace was dark brown with a narrow white rim and had low tubercules. The abdomen was white with two black patc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exechocentrus
''Exechocentrus'' is a genus of Madagascan orb-weaver spiders (family Araneidae) first described by Eugène Simon in 1889. It is a bolas-using spider, capturing its prey with one or more sticky drops at the end of a single line of silk rather than in a web. Description Males of the genus are unknown. Females can be distinguished from all other known members of the family Araneidae by the spine-like projections on the cephalothorax. One is centrally placed and extends forwards; three are more-or-less upright. The total body length is . The cephalothorax is yellowish-white with brown lines radiating from the fovea and is about as wide as it is long. The legs are pale yellowish-white with dark brown markings. The abdomen is off white and almost heart-shaped from above. The epigyne has a strongly hardened (sclerotized) lip. The spermathecae are large and ovoid, with short narrow copulatory ducts.

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

World Spider Catalog
The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of individual web pages in 2000, created by Norman I. Platnick of the American Museum of Natural History. After Platnick's retirement in 2014, the Natural History Museum of Bern (Switzerland) took over the catalog, converting it to a relational database. , 50,151 accepted species were listed. The order Araneae Spiders (order Araneae) 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 dive ... (spiders) has the seventh-most species of all orders.

''Taczanowskia'' is a genus of Araneidae, orb-weaver spiders first described by Eugen von Keyserling in 1879. Contrary to the common name of the group, spiders of the genus Taczanowskia do not build webs and are furtive hunters, deceiving their prey by producing sex pheromones that attract male moths, and catching their prey by using a pair of enlarged claws at the tip of their anterior legs.
