Macrothele
''Macrothele'' is a genus of mygalomorph spiders in the family Macrothelidae, and was first described by A. Ausserer in 1871. It is the only genus in the family Macrothelidae, and most species occur in Asia, from India to Japan, and Java, with five found in Africa, and two in Europe. The name is derived from Ancient Greek μακρός ("makro-"), meaning "big", and θηλή ("thele"), referring to the spinnerets. Description Spiders of this genus are fairly large, with females of some Chinese species ranging from in body length. Males are smaller, sometimes only half that length. Macrothelids can be distinguished from other mygalomorph spiders by their larger posterior sigillae on the sternum, and the arrangement of the rows of teeth on the margin of the chelicerae: larger front-facing margin and smaller rear-facing. These spiders build tube-webs or funnel-webs under rocks or logs, or in crevices in the ground. Taxonomy The genus ''Macrothele'' was erected by Anton Ausse ...

Macrothele Calpeiana
''Macrothele calpeiana'', commonly known as the Gibraltar funnel-web spider or Spanish funnel-web spider, is one of the largest spiders in Europe. ''Macrothele calpeiana'' is the only spider species protected under European Union legislation.Arnedo, M.A., Ferrández, M. (2007) "Mitochondrial markers reveal deep population subdivision in the European protected spider ''Macrothele calpeiana'' (Walckenaer, 1805) (Araneae, Hexathelidae)". ''Conserv Genet'' 8, 1147–1162. . The satin black colour and long, flexible spinnerets are characteristic of this spider. The carapace is low and flat and the eyes are in a compact group. The female resembles the male but has a larger abdomen. The male can grow to nearly long; females are typically larger. Like all funnel-web spiders, this spider's web is funnel-shaped with trip-threads around the entrance, built among stones and roots. Its geographical range includes Gibraltar ) , anthem = " God Save the King" , song = " Gibraltar Anthe ... [...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 3000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to them forming 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 realized that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the br ...

In 2018, the family was substantially reduced in size by genera being moved to three separate families: Atracidae, Macrothelidae and Porrhothelidae. Atracidae includes the most venomous species formerly placed in Hexathelidae. 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 dipluridae, diplurid spiders, the hexathelids have generally long spinneret (spider), spinnerets. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hebestatis
''Hebestatis'' is a genus of mygalomorph spiders in the family Halonoproctidae, first described by Eugène Simon Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider taxonomist in history, describing over 4, ... in 1903. it contains only two species: ''H. lanthanus'' and ''H. theveneti''.

Actinopodidae
Actinopodidae ( Mouse spiders) is a family of mygalomorph orb weaver spiders found in mainland Australia and South America usually in open forest. Species are most common in Queensland, Australia. It includes mouse spiders, whose bites, though rare, are considered medically significant and potentially dangerous. Description Actinopodidae has wider vision then most other Australian mygalomorphs and have a wide front to there carapace. Mouse spiders are stout black with species size varying from 10 mm-35 mm in length. Species have distinctively bulbous heads and jaw regions. Mouse spiders are oftentimes confused with funnel-web spiders. Depending on the species, the abdomen is black or dark blue with a light grey to white patch top. Legs are dark and may appear thin and the head is shiny black. Female of the family are stockier and larger. Burrow Mouse spiders live in soil covered burrows with a hinged top. Burrows can extent to a depth of 30 cm (12 inches). Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 results ...

Cladogram
A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other evolutionary narratives about an ...
