Porrhothele Modesta
''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 ...

Porrhothele Antipodiana
''Porrhothele antipodiana'', the black tunnelweb spider, is a spider found throughout much of New Zealand and the Chatham Islands in bush and gardens and is one of New Zealand's most researched spiders. It is related to tarantulas, and is a harmless relative of the venomous Australian funnel-web spider. Description In females, the carapace is usually coloured yellow or orange black with some shading near the eyes. The legs and palps are also typically orange brown, but are darker than the carapace. The chelicerae are reddish brown (sometimes black). The sternum is a pale reddish brown. The abdomen is a uniform purple black colour and may have faint chevron patterns, more noticeable in juveniles. The opening of the two pairs of book lungs are ringed with cream. Females are the larger of the two sexes. Body size is variable, but can exceed 30 mm. In males, the carapace is darker than in females. The legs and palps are a dark reddish brown. The chelicerae are also dark redd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ance ...

Mygalomorphae Genera
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 branching ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

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). The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
