Anelosimus Eidur
''Anelosimus eidur'' is a species of tangle-web spider found in Papua New Guinea. Its habitat is high elevation scrub forest, in Southern Highlands Province and Enga Province Enga is one of the provinces in Papua New Guinea (PNG). It is located in the north most region of the highlands of PNG, having been divided from the Western Highlands to become a separate province when the provinces were created at the time of in .... It has a total length of , with the females being larger than the males. It can be identified by its unique genitalia, particularly the spiraling embolus in the males. The web structure is similar to social and sub-social species, leading to its tentative identification as subsocial. The species is named Eiður Francis, the son of Ingi Agnarsson who first identified the species in 2012. References Theridiidae Spiders of Oceania Spiders described in 2012 {{Theridiidae-stub ...

Tangle-web Spider
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. Theridiid spiders are both entelegyne, meaning that the females have a genital plate, and ecribellate, meaning that they spin sticky capture silk instead of woolly silk. They have a comb of serrated bristles ( setae) on the tarsus of the fourth leg. The family includes some model organisms for research, including the medically important widow spiders. They are important to studies characterizing their venom and its clinical manifestation, but widow spiders are also used in research on spider silk and sexual biology, including sexual cannibalism. ''Anelosimus'' are also model organisms, used for the study of sociality, because it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papua New Guinea
Papua New Guinea (abbreviated PNG; , ; tpi, Papua Niugini; ho, Papua Niu Gini), officially the Independent State of Papua New Guinea ( tpi, Independen Stet bilong Papua Niugini; ho, Independen Stet bilong Papua Niu Gini), is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia (a region of the southwestern Pacific Ocean north of Australia). Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country, with an area of . At the national level, after being ruled by three external powers since 1884, including nearly 60 years of Australian administration starting during World War I, Papua New Guinea established its sovereignty in 1975. It became an independent Commonwealth realm in 1975 with Elizabeth II as its queen. It also became a member of the Commonwealth of Nations in its own right. There are 839 known languages of Papua New Guinea, one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Highlands Province
Southern Highlands is a province in Papua New Guinea. Its provincial capital is the town of Mendi. According to Papua New Guinea's national 2011 census, the total population of Southern Highlands (after the separation of Hela Province) is 515,511 spread across . Ethnic groups Before the split there were two major ethnic groups, the Huli people and the Angal speakers. Today the majority of the population in Southern Highlands is made up of Angal or Angal Heneng speakers. They occupy the three provinces of Southern Highlands (Nipa, Mendi, Lai Valley, Imbongu (lower Mendi)), Hela (Magarima) and Enga (parts of Kandep). Split to create Hela Province In July 2009, Parliament passed legislation to create two new provinces by 2012. One of these was to be created by removing the districts of Tari-Pori, Komo-Magarima, and Koroba-Kopiago from the Southern Highlands Province to form the new Hela Province. Hela Province officially came into being on 17 May 2012. Regions After the split of H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enga Province
Enga is one of the provinces in Papua New Guinea (PNG). It is located in the north most region of the highlands of PNG, having been divided from the Western Highlands to become a separate province when the provinces were created at the time of independence in 1975. The people of Enga are called Engans—they are a majority ethnic group—speaking one language in all its five districts: approximately 500,000 people. A small minority of Engans' land on the eastern side of the region remained in the Western Highlands, their territory being accessible by road from Mount Hagen but not directly from elsewhere in Enga territory. History Europeans—typically Australian gold prospectors—originally entered what is now Enga province from the east in the late 1920s, although the best-known exploration of Enga took place during the early 1930s when Mick Leahy and a party of men travelled from what later became Mount Hagen to the site of the future Wabag and then south through the Ambum Val ...

Embolus (spider Anatomy)
The two palpal bulbs – also known as palpal organs and genital bulbs – are the copulatory organs of a male spider. They are borne on the last segment of the pedipalps (the front "limbs" of a spider), giving the spider an appearance often described as like wearing boxing gloves. The palpal bulb does not actually produce sperm, being used only to transfer it to the female. Palpal bulbs are only fully developed in adult male spiders and are not completely visible until after the final moult. In the majority of species of spider, the bulbs have complex shapes and are important in identification. Structure The palpal bulb of a mature male spider is borne on the last segment of the pedipalp. This segment usually has touch-sensitive hairs (setae) with nerves leading to them. The bulb itself is entirely without nerves, and hence without sensory organs and muscles, since these depend on nerves for their functioning, although some spiders have one or two muscles external to the bulb and ...

Spiders Of Oceania
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 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. , 50,356 spider species in 132 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. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a se ...
