Nephilingis
''Nephilingis'' is a genus of spiders in the family Araneidae. It was split off from the genus '' Nephilengys'' in 2006. Both genera have been called hermit spiders from the habit of staying in their retreats during the day; alternatively the name "hermit spider" may be reserved for ''Nephilingis'', with ''Nephilengys'' species called "eunuch spiders". Description Females of species in the genus ''Nephilingis'' are large spiders, with a body length of . The epigynum is wider than long, without a central septum or anterior rim – distinguishing them from females of ''Nephilengys''. Males are considerably smaller. The conductor of the palpal bulb is short, wide and spiraled. Species of ''Nephilingis'', like those of ''Nephilengys'', build large asymmetric webs on trees with a hiding retreat in which they hide during the day. The webs make use of branches and similar supports but are mainly aerial, contrasting with those of other nephiline species, whose webs follow the contour ...

Nephilingis Borbonica
''Nephilingis borbonica'' is an araneid spider from Réunion. It was once thought to also inhabit Madagascar and other nearby islands, however these were determined in 2011 to be a different species, '' Nephilingis livida'', while specimens from Mauritius were placed in the new species ''Nephilingis dodo''.Kuntner & Agnarsson 2011Biogeography and diversification of hermit spiders on Indian Ocean islands (Nephilidae: Nephilengys) ''Molecular Phylogenetics and Evolution'' 59:477–488.

Nephilingis Cruentata
''Nephilingis cruentata'' is an araneid spider with a strikingly red sternum. Females reach a length of about 24 mm. The legs can be uniformly dark red or brown, or annulated. Males are about 4 mm long. Taxonomy The species was first described in 1775 by Johan Fabricius, as ''Araneus cruentata''. In 1887, Eugène Simon transferred it to the genus '' Nephilengys''. In 2013, Matjaž Kuntner et al. decided that four species of ''Nephilengys'' were sufficiently different to require an alternative generic placement. Accordingly, they erected the genus ''Nephilingis'' with ''Nephilingis cruentata'' as the type species. Distribution ''N. cruentata'' is found in tropical and subtropical Africa and several limited areas of South America (Brazil, northern Colombia and Paraguay Paraguay (; ), officially the Republic of Paraguay ( es, República del Paraguay, links=no; gn, Tavakuairetã Paraguái, links=si), is a landlocked country in South America.

Nephilingis Livida
''Nephilingis livida'' is an araneid spider from Madagascar and nearby islands. It was found to be separate from the related species ''Nephilingis borbonica'' in 2011Kuntner & Agnarsson 2011Biogeography and diversification of hermit spiders on Indian Ocean islands (Nephilidae: Nephilengys) ''Molecular Phylogenetics and Evolution'' 59:477-488. Etymology The species name is derived from Latin "lividus", which can mean "malicious" as well as "bluish". Description The color of the female's abdomen ranges from creamy to brown, blue or purple, with a dark brown venter. Females reach a length of about 15 to 24mm Males only reach a length of 3 to 5 mm and have a yellow-brown sternum and a grey abdomen with white dots.

Nephilinae
Nephilinae is a spider subfamily of the family Araneidae with seven genera. The various genera in Nephilinae were formerly grouped in the family Nephilidae, and before that in the Tetragnathidae and in the Araneidae (where they have been restored). All nephiline genera partially renew their webs. Spiders in the subfamily Nephilinae are commonly referred to as golden orb-weavers. Reproductive behavior The genera '' Herennia'', '' Nephilengys'' and ''Nephilingis'' display extreme sexually driven selection. The pedipalps of these genera have become highly derived by evolving enlarged, complex palpal bulbs which break off inside the females' copulatory openings after copulation. The broken palps serve as mating plugs, which makes future matings with a mated female more difficult. These genera of spiders also participate in mate guarding; a mated male will stand guard by his female and chase off other males, thereby increasing the mated male's paternity share. Mated males are castrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nephilingis Dodo
''Nephilingis dodo'' is an araneid spider endemic to Mauritius.

Nephilengys
''Nephilengys'' is a genus of tropical spiders of the family Araneidae, consisting of two currently described species. (The genus was formerly placed in the Nephilidae and Tetragnathidae.) The genus ''Nephilingis'' has been split off from this genus. Both genera have been called hermit spiders from the habit staying in their retreats during the day; the name eunuch spiders has been used for ''Nephilengys'' alone. Males may sever parts of their palpal bulbs after copulation. Description Females are from 10 mm to 28 mm long, with males typically only reaching about 5mm. The prosoma has a wide and high head region. The carapace features strong erect spines. The edges of the carapace are lined with a row of long white hairs. Males are 3–6 mm long. Habits ''Nephilengys'' is the most synanthropic (found in and around human dwellings) of the nephiline genera. They build their webs against substrates such as tree trunks or walls. These can have a diameter of up to one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araneidae
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs. The family has a cosmopolitan distribution, including many well-known large or brightly colored garden spiders. With 3,108 species in 186 genera worldwide, the Araneidae comprise the third-largest family of spiders (behind the Salticidae and Linyphiidae). Araneid webs are constructed in a stereotypical fashion, where a framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets. Orb webs are also produced by members of other spider families. The long-jawed orb weavers ( Tetragnathidae) were formerly included in the Araneidae; they are closely related, being part of the superfamily Aran ...

Araneomorphae Genera
The Araneomorphae (also called the Labidognatha) are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae (tarantulas and their close kin), where they point straight down. Araneomorphs comprise the vast majority of living spiders. Distinguishing characteristics Most spider species are Araneomorphae, which have fangs that face towards each other, increasing the orientations they can employ during prey capture. They have fewer book lungs (when present), and the females typically live one year. The Mygalomorphae have fangs that face towards the ground, and which are parallel to the long axis of the spider's body, thus they have only one orientation they can employ during prey capture. They have four pairs of book lungs, and the females often live many years. Image:Atrax robustus.jpg, This '' Atrax robustus'' shows the orientation of Myglamorphae fangs. Image ...

Seychelles
Seychelles (, ; ), officially the Republic of Seychelles (french: link=no, République des Seychelles; Creole: ''La Repiblik Sesel''), is an archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and Maldives and the Chagos Archipelago (administered by the United Kingdom as the British Indian Ocean Territory) to the east. It is the least populated sovereign African country, with an estimated 2020 population of 98,462. Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until coming under full British control in the late 18th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aldabra
Aldabra is the world's second-largest coral atoll, lying south-east of the continent of Africa. It is part of the Aldabra Group of islands in the Indian Ocean that are part of the Outer Islands of the Seychelles, with a distance of 1,120 km (700 mi) southwest of the capital, Victoria on Mahé Island. History The name Aldabra, originally Al-Hadra or Al-Khadra (with several variants), was given by Arab seafarers for "the atoll’s harsh, sun-baked environment"; this name was included in the Portuguese maps of the 16th century. The islands were already known to the Persians and Arabs, from whom they got their name. They had named the Indian Ocean as Bahr-el zanj. It was visited by Portuguese navigators in 1511. In the middle of the 18th century, the atoll became a dependency of the French colony of Réunion, from where expeditions were made for the capture of the Aldabra giant tortoises. As there are no surface freshwater sources on Aldabra, the interests of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
