Hexathelidae
Hexathelidae is a family of mygalomorph spiders. It is one of a number of families and genera of spiders known as tunnelweb or funnel-web spiders. In 2018, the family was substantially reduced in size by genera being moved to three separate families: Atracidae, Macrothelidae and Porrhothelidae. Description These spiders are medium to large in size, with body lengths ranging from . The body is typically three times longer than it is wide. They are darkly colored, ranging from black to brown, with a glossy carapace covering the front part of the body. Like the related diplurid spiders, the hexathelids have generally long spinnerets. Their moderately long posterior spinnerets and other features make the Hexathelidae appear similar to the Dipluridae, and were considered a subfamily of the latter until 1980. Like other Mygalomorphae (also called the Orthognatha, an infraorder of spiders which includes the true tarantulas), these spiders have fangs which point straight down ...

Plesiothele
''Plesiothele'' is a monotypic genus of Australian funnel-web spiders containing the single species, ''Plesiothele fentoni'', also known as Lake Fenton trapdoor spider. The genus was first described by Robert John Raven in 1978, and has only been found in Tasmania, Australia. Originally placed with the curtain web spiders, it was moved to the Hexathelidae in 1980. ''Plesiothele fentoni'' is a ground-dwelling spider that lives in lidless, silk-lined burrows some deep. It grows to in length. The abdomen The abdomen (colloquially called the gut, belly, tummy, midriff, tucky, or stomach) is the front part of the torso between the thorax (chest) and pelvis in humans and in other vertebrates. The area occupied by the abdomen is called the abdominal ... is yellow-brown and strongly patterned.

Hexathele
''Hexathele'' is a genus of tunnelweb spiders endemic to New Zealand that was first described by Anton Ausserer in 1871, though most others have been described by Raymond Robert Forster. Originally placed with the curtain web spiders, it was moved to the Hexathelidae in 1980. Description Most species of ''Hexathele'' are relatively large spiders. Females of '' Hexathele waita'', one of the largest species, may have a carapace long, and an abdomen long, with the longest leg (the fourth) being long in total. ''Hexathele'' species are generally brown to black in colour. Many species have a chevron pattern on the upper surface of the abdomen, with patterns often being unique to the species. The carapace of the cephalothorax has a more or less straight depression ( fovea) in the centre. The eyes are arranged in a compact group. The male palp lacks tibial apophyses (projections), but the male's first pair of legs have double spines on the tibia. There are six spinnerets, with the ...

Porrhothelidae
''Porrhothele'' is a genus of mygalomorph spiders endemic to New Zealand. They are the only members of the family Porrhothelidae. They were first described by Eugène Louis Simon in 1892. Originally placed with the curtain web spiders, it was moved to the Hexathelidae in 1980, they were placed in their own family in 2018. Members of Porrhothelidae are distinguished from other mygalomorph spiders by the small posterior sigillae and a single row of teeth on the forward-facing margin of the chelicerae. Males have many strong spines on the forward-facing margin of their tibiae. Taxonomy The genus ''Porrhothele'' was erected by Eugène Simon in 1892 for the species '' Porrhothele antipodiana''. Simon transferred these from ''Mygale'', a genus previously used for many mygalomorph spiders, but is no longer in use. He placed this genus in the subfamily Diplurinae, which later became the family Dipluridae. Raven transferred the genus to Hexathelidae, where it remained until the re ...

Hexathele Hochstetteri
''Hexathele hochstetteri'', commonly known as the banded tunnelweb spider, is a spider in the family Hexathelidae, found only in New Zealand. It is common on the North Island, and uncommon on the South Island. Description The banded tunnelweb spider (''Hexathele hochstetteri'') is among New Zealand's largest spiders, growing up to 20 mm in body length, and is endemic Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also foun ... to New Zealand. The easiest way to distinguish a banded tunnelweb spider is to look for the chevron design on its abdomen. The chevron pattern is described as being yellowish, whilst the rest of the abdomen is a darker brown colour. They also have an orange-brown carapace, and six spinnerets. It is these six spinnerets that ultimately distinguish ''Hexathele hoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mygalomorphae
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3,000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to their creation of trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs. Description This group of spiders comprises mostly heavy-bodied, stout-legged spiders including tarantulas, Australian funnel-web spiders, mouse spiders, and various families of spiders commonly called trapdoor spiders. Like the " primitive" suborder of spiders Mesothelae, they have two pairs of book lungs, and downward-pointing chelicerae. Because of this, the two groups were once believed to be closely related. Later it was realised that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the ...

Spider
Spiders (order (biology), order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude spider silk, silk. They are the largest order of arachnids and rank seventh in total species diversity among all Order (biology), orders of organisms. Spiders are found worldwide on every continent except Antarctica, and have become established in nearly every land habitat. , 53,034 spider species in 136 Family (biology), families have been recorded by Taxonomy (biology), taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomy, Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segmentation (biology), segments are fused into two Tagma (biology), tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindr ...
