Porrhothele
''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 result ...

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] |

Hexathelidae
Hexathelidae is a family of mygalomorph spiders. It is one of a number of families and genera of spiders known as funnel-web spiders. 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 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 taran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Spiders Of New Zealand
New Zealand has 1157 described spider species, with an estimated total fauna of 2000 species. Over 97 per cent are endemic, and the rest have been introduced through human activities or were natural wind-borne introductions. The New Zealand spider with the largest leg span is the Nelson cave spider (''Spelungula cavernicola''), with a leg span of up to and a body length. The Australian white-tailed spider, first recorded in New Zealand in 1886, has been falsely attributed as the cause of many necrotising spider bites. The flat huntsman spider (''Delena cancerides''), also from Australia, and called the Avondale spider in New Zealand, was accidentally introduced in the early 1920s, possibly in shipments of hardwood logs used for railway sleepers.Rowell and Avilés (1995).

Dipluridae
The family Dipluridae, known as curtain-web spiders (or confusingly with other distantly related ones as funnel-web tarantulas) are a group of spiders in the infraorder Mygalomorphae, that have two pairs of booklungs, and chelicerae (fangs) that move up and down in a stabbing motion. A number of genera, including that of the Sydney funnel-web spider (''Atrax''), used to be classified in this family but have now been moved to Hexathelidae. Description Dipluridae lack a rastellum (stout conical spines) on their chelicerae. Their carapace is characterized by the head region not being higher than the thoracic region. Their posterior median spinnerets (silk-extruding organs) are much shorter than their posterior lateral spinnerets, which have three segments, and are elongated (almost as long as their opisthosoma). Most of the species are medium to small-sized spiders; some may measure about 15 mm.Murphy & Murphy 2000 The cave species ''Masteria caeca'' is eyeless. Biology Mem ...
