Stanwellia grisea, also known as the Melbourne trapdoor spider, is a species of mygalomorph spider in the Pycnothelidae family. It is endemic to Australia. It was described in 1901 by British arachnologist Henry Roughton Hogg. [1] [2]

Description

Female spiders grow up to 35 mm in body length; males to 25 mm. The body is brown; the abdomen may be paler with a darker, rib-like pattern on the upper surface. Large cheliceral fangs are displayed when the spider feels threatened. [3]

Distribution and habitat

The spiders are found in southern Victoria in tall open forest habitats. Their range includes the environs of the city of Melbourne and the Grampian Mountains. The type locality is Macedon. [2]

Behaviour

The spiders are fossorial, terrestrial predators. [2] Both males and females dig individual silk-lined burrows, up to 40 cm deep in soft earth, with silk threads radiating from the entrances. They ambush insects and other small prey at night from the burrow entrances which, despite the common name, do not have trapdoors. During autumn and early winter, males leave their burrows and wander widely in search of mates. [3]

Interactions with humans

The spiders, especially the roaming males, can be encountered in gardens and urban areas. Their fangs are capable of delivering a deep and painful bite, which may cause a local reaction. [3]

Atracidae is a family of mygalomorph spiders, commonly known as Australian funnel-web spiders or atracids. It has been included as a subfamily of the Hexathelidae, but is now recognised as a separate family. All members of the family are native to Australia. Atracidae consists of three genera: Atrax, Hadronyche, and Illawarra, comprising 35 species. Some members of the family produce venom that is dangerous to humans, and bites by spiders of six of the species have caused severe injuries to victims. The bites of the Sydney funnel-web spider and northern tree-dwelling funnel-web spider are potentially deadly, but no fatalities have occurred since the introduction of modern first-aid techniques and antivenom.

The Sydney funnel-web spider is a species of venomous mygalomorph spider native to eastern Australia, usually found within a 100 km (62 mi) radius of Sydney. It is a member of a group of spiders known as Australian funnel-web spiders. Its bite is capable of causing serious illness or death in humans if left untreated.

<i>Selenocosmia crassipes</i> Species of spider

Selenocosmia crassipes, synonym Phlogius crassipes, also known as the "Queensland whistling tarantula", "barking spider" or "bird-eating tarantula" is a species of tarantula native to the east coast of Queensland, Australia. The name "whistling tarantula" comes from its ability to produce a hissing noise when provoked, a trait it shares with other Australian theraphosids. This hissing is produced by the spider stridulating a patch of setae associated with its chelicerae. It has also been called the "eastern tarantula". The species name crassipes is Latin for "fat leg" referring to the relatively fat front legs.

<span class="mw-page-title-main">Nemesiidae</span> Family of spiders

Nemesiidae is a family of mygalomorph spiders first described by Eugène Simon in 1889, and raised to family status in 1985. Before becoming its own family, it was considered part of "Dipluridae". The family is sometimes referred to as wishbone spiders due to the shape of their burrows.

<i>Idiosoma</i> Genus of spiders

Idiosoma is a genus of Australian armoured trapdoor spiders that was first described by Anton Ausserer in 1871. Originally placed with the Ctenizidae, it was moved to the armoured trapdoor spiders in 1985. The name is derived from the Greek ἴδιος, meaning "individual, unique", and σῶμα, meaning "body", referring to the distinctive structure of the abdomen.

<i>Porrhothele antipodiana</i> Black tunnelweb spider from New Zealand

Porrhothele antipodiana, the black tunnelweb spider, is a species of mygalomorph spider that lives in New Zealand. It is the most common and widespread of several species in the genus Porrhothele, and is especially common in the greater Wellington region where the vagrant mature males are often encountered in or around dwellings. This species is one of New Zealand's most studied spiders. In New Zealand, the common name "tunnelweb spider" is also often used to refer to members of the genus Hexathele. Neither should be confused with their distant relatives, the highly venomous Australian funnel-web spiders.

<i>Stanwellia</i> Genus of spiders

Stanwellia is a genus of South Pacific mygalomorph spiders in the family Pycnothelidae. It was first described by W. J. Rainbow & R. H. Pulleine in 1918. Originally placed with the curtain-web spiders, it was transferred to the funnel-web trapdoor spiders in 1985, then to the Pycnothelidae in 2020. It is a senior synonym of Aparua.

<span class="mw-page-title-main">Tarantula</span> Family of spiders

Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. As of December 2023, 1,100 species have been identified, with 166 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.

<i>Selenocosmia stirlingi</i> Species of spider

Selenocosmia stirlingi is a species of tarantula that is native to the arid regions of Australia. It is sometimes also referred to as a barking spider or whistling spider as this species, like many tarantulas, can stridulate to produce a "hissing" sound when disturbed or threatened. This species is largely fossorial, living in burrows deep underground, however males are sometimes encountered during the breeding season.

Atrax yorkmainorum is a venomous species of Australian funnel-web spider belonging to the Atracidae family and is found in forests in the vicinity of Canberra and south-eastern New South Wales. The genus Atrax was first documented in 1877 and the Atrax yorkmainorum species was first described in 2010.

<i>Eucteniza</i> Genus of spiders

Eucteniza is a genus of trapdoor spiders in the family Euctenizidae containing at least 14 species occurring in Mexico and the southern United States. Species are distinguished by a softened rear portion of the carapace, and males possess large spines on the first two pairs of walking legs that are used to hold females during mating. Like other trapdoor spiders they create burrows with a hinged lid, from which they await passing insects and other arthropods to prey upon. Many species are known from only one or two localities, or from only male specimens. More species are expected to be discovered. Eucteniza is closely related to spiders of the genera Entychides and Neoapachella.

<i>Tasmanicosa godeffroyi</i> Species of spider

Tasmanicosa godeffroyi, a wolf spider, is a mid sized spider found in some states of Australia. It is perhaps the most commonly noticed of the wolf spiders in Australia. It is variable in pattern and colour, though the underside of the abdomen is black. Wolf spiders tend to rest at the entrance of their burrows, and their eyes reflect the light of passing cars or torchlight. The burrow has a thin veil of silk, without a lid, unlike some other wolf spiders. The burrow is circular in cross section and travels down for around 15 cm, then parallel with the ground for the next 15 cm. The body length of the female is up to 27 mm, the male 25 mm.

<i>Arbanitis robertsi</i> Species of spider

Arbanitis robertsi is a species of tube-dwelling spider in the family Idiopidae found in and near rainforests in New South Wales and Queensland, Australia. A mid to large sized spider which builds a tube of web that extends from the burrow. The tube is attached to rocks, tree ferns or the base of trees. Thousands of these tubes were recorded by Sid Jackson in November 1922 at the south eastern end of Wallis Lake. "Up to three feet long, and half an inch wide". Situated on damp ground, close to freshwater streams.
