Nephilidae
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 castrated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Herennia
''Herennia'' is a genus of spiders in the Family (biology), family Araneidae, found from India to northern Australia. It was formerly placed in a separate family, Nephilidae. While two species have been known since the 19th century, nine new species were described in 2005. Spiders in this genus are sometimes called coin spiders. While ''H. multipuncta'' is invasive species, invasive and synanthropic, all other known species are endemic (ecology), endemic to islands. Like in the related genus ''Nephilengys'', the much smaller males mutilate and sever their pedipalps, which are often found stuck in the epigynum or female genital openings. It is suggested that they act as mating plugs to prevent other males from mating with the female and thereby ensure the paternity of offspring. The males cannot mate subsequently and such "eunuch" individuals continue to stay near the female. Name Herennia Etruscilla was the wife of Trajan Decius. There are coins bearing her image, which were pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Clitaetra
''Clitaetra'' is a genus of spiders in a family Araneidae. It was formerly placed in a separate family, Nephilidae. It occurs in Africa, Madagascar and Sri Lanka, hinting to a Gondwanan origin. a split between ''Clitaetra'' and related genera may be as old as 160 million years.Kuntner, M. 2006.

Nephila Constricta
''Nephila'' is a genus of araneomorph spiders noted for the impressive webs they weave. ''Nephila'' consists of numerous species found in warmer regions around the world. They are commonly called golden silk orb-weavers, golden orb-weavers, giant wood spiders, or banana spiders. Etymology The genus name ''Nephila'' is derived from Ancient Greek, meaning "fond of spinning", from the words νεῖν (''nein'') = to spin (related to ''nema'' νήμα "thread") + φίλος (''philos'') = "love". Description ''Nephila'' spiders vary from reddish to greenish yellow in color with distinctive whiteness on the cephalothorax and the beginning of the abdomen. Like many species of the superfamily Araneoidea, most of them have striped legs specialized for weaving (where their tips point inward, rather than outward as is the case with many wandering spiders). Their contrast of dark brown/black and green/yellow allows warning and repelling of potential predators to which their venom might be ...

Spider
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 ...

Friedrich Dahl
Karl Friedrich Theodor Dahl (June 24, 1856 in Rosenhofer Brök north of Dahme, Holstein – June 29, 1929 in Greifswald) was a German zoologist, and in particular an arachnologist. The son of a farmer, Dahl studied at the universities of Leipzig, Freiburg, Berlin and Kiel. His dissertation (1884) was "''Beiträge zur Kenntnis des Baus und der Funktion der Insektenbeine''". He became a '' Privatdozent'' in 1887; with a habilitation thesis "''Ueber die Cytheriden der westlichen Ostsee''". Around this time he traveled to the Baltic states and (1896–1897) to the Bismarck Archipelago near New Guinea. He was also interested in biogeography. On April 1, 1898 Dahl became curator of arachnids at the ''Museum für Naturkunde'' in Berlin, where he worked under his former teacher, the then museum director Karl Möbius. Dahl remained in Berlin until he retired, and his type collection is held in that museum. Although he described in many animal groups, Dahl concentrated on spider ...

Trichonephila
''Trichonephila'' is a genus of orb-weaver spiders that was first described by Friedrich Dahl in 1911, as a subgenus of ''Nephila''. ''Trichonephila'' was elevated to the level of genus (new rank) by Kuntner ''et al.'' in 2019. The genus ''Trichonephila'' belongs to the Araneidae family, also known as the orb weavers. The family Araneidae belongs within the superfamily of Araneoidea, comprising 18 families. Araneidae family members can be identified by looking for three-clawed spiders that have eight eyes spanned across two sets which form a trapezoid shape, on webs with a sticky glue like feeling. The very diverse Araneidae family is most famously known for their elaborate webs they spin, which are webs made of concentric circles with spokes extending out from the center. In few species of the spiders, you can find a zigzag shape going down the center of the web. Identifying the species of these spiders is not easy with the eye alone, it breaks down into phylogenomic variations bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
