Ctenizidae
Ctenizidae is a small family of mygalomorph spiders that construct burrows with a cork-like trapdoor made of soil, vegetation, and silk. They may be called trapdoor spiders, as are other, similar species, such as those of the families Liphistiidae, Barychelidae, and Cyrtaucheniidae, and some species in the Idiopidae and Nemesiidae. The name comes from the distinctive behavior of the spiders to construct trapdoors, and ambush prey from beneath them. In 2018, the family Halonoproctidae was split off from the Ctenizidae. A further genus, ''Stasimopus'', was split off into its own family, Stasimopidae, in 2020. The family currently consists of two genera and five species. Etymology The name derives from Greek ''ktenizein'', meaning "combing" or "cleaning", referring to their behaviour of cleaning continuously, and the suffix "-idae", which designates belonging to a family. Taxonomy The family Ctenizidae was first described by Thorell in 1887, being based on the genus ''Cteniza' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mygalomorph
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 ...

Halonoproctidae
Halonoproctidae is a family of mygalomorph spiders, split off from the family Ctenizidae in 2018. Species in the family are widely distributed in North and Central America, Australasia, Asia, southern Europe and North Africa. One species is recorded from Venezuela in South America. They are relatively large, sombrely coloured spiders, that live in burrows with some kind of trapdoor. Description Spiders of the family Halonoproctidae are of a medium to large size for spiders. They construct burrows with some kind of trapdoor, either wafer-like or cork-like. They range in colour from light brown to black, usually without any strongly distinctive body markings. The carapace is usually without hairs and has only a few spines. The sternum is longer than it is wide, and has sigillae at least in the posterior part. The eyes are arranged in two or three rows. Females do not have scopulae on their legs, but do have unique curved, thorn-like spines on the sides of legs I and II. Males have ...

Cteniza Sauvagesi
''Cteniza sauvagesi'' is a trapdoor spider first described in 1788 by Pietro Rossi. These spiders have only been found in the Mediterranean region, mainly on the large islands of Corsica and Sardinia on roadside banks and in the littoral zone. They are darkly colored with a shiny head and can reach in length. Their trap-door burrows are lined with gossamer, more so than those of ''Nemesiidae Nemesiidae, also known as funnel-web trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889, and raised to family status in 1985.

When the spider notices prey (probably by detecting vibration), it lunges out, to grab it before immediately retreating. The spider always stays inside its burrow with its hindlegs, in order not to lock itself out. The only time it leaves is to search for a mate. When ...

Spiders
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...

Myrmekiaphila
''Myrmekiaphila'' is a genus of North American mygalomorph trapdoor spiders in the family Euctenizidae, and was first described by G. F. Atkinson in 1886. All described species are endemic to the southeastern United States. Originally placed with the Ctenizidae, it was moved to the wafer trapdoor spiders in 1985, then to the Euctenizidae in 2012. ''Myrmekiaphila'' appears as the sister group to all southwestern Euctenizidae with the exception of '' Apomastus'', which in turn is the sister group to all euctenizines. ''M. flavipes'' was transferred from ''Aptostichus'' in 2007. Description The known species of this genus resemble each other in appearance and behavior. The carapace is long and wide. Females are uniformly colored, with some dusky stripes on the dorsum of the abdomen. Colors range from yellowish red to dark reddish brown. The palpal tibia of the males are modified in a way that distinguishes them from other mygalomorph spiders of North America. The first legs in ma ...

Baltic Amber
The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that these forests created more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014, 400 tonnes in 2015. "Baltic amber" was formerly thought to include amber from the Bitterfeld Lignite, brown coal mines in Saxony (Eastern Germany). Bitterfeld amber was previously believed to be only 20–22 million years old (Miocene), but a comparison of the animal inclusions in 2003 suggested that it was possibly Baltic amber that was redeposited in a Miocene deposit. Further study of insect taxa in the ambers has shown Bitterfeld amber to be from the same forest as the Baltic amber forest, but separately deposited f ...

List Of Trapdoor Spiders
Trapdoor spider is a common name that is used to refer to various spiders from several different groups that create burrows with a silk-hinged trapdoor to help them ambush prey. Several families within the infraorder Mygalomorphae contain trapdoor spiders: * Actinopodidae, a family otherwise known as 'mouse-spiders', in South America and Australia * Antrodiaetidae, a family of 'folding trapdoor spiders' from the USA and Japan * Barychelidae, a family of 'brush-footed trapdoor spiders' with pantropical distribution * Ctenizidae, a family of 'Cork (material), cork-lid trapdoor spiders' in Tropics, tropical and subtropics, subtropical regions * Cyrtaucheniidae, a family of 'wafer-lid trapdoor spiders, with wide distribution except cooler regions * Euctenizidae, a family of spiders that make wafer-like or cork-like trapdoors * Halonoproctidae, a family of spiders that make wafer-like or cork-like trapdoors and includes the phragmosis, phragmotic genus ''Cyclocosmia'' * Idiopidae, a fam ...

Cyrtaucheniidae
The wafer trapdoor spiders, family Cyrtaucheniidae, are a widespread family of spiders that lack the thorn-like spines on tarsi and metatarsi I and II (the two outermost leg segments) found in true trapdoor spiders (Ctenizidae). Etymology The scientific family name derives from the Greek κυρταύχην, ''kyrtaúchēn'', which in turn is derived from Greek κυρτός ''kyrtós'', meaning "curved", "arched" or "bent", αὐχήν ''auchen'', meaning the cervix or neck, and the suffix -''idae'', which designates belonging to a family. Biology Many, but not all, make wafer-like doors to their burrows, while others build the cork-like doors found commonly in the true trapdoor spiders. The biology of nearly all the species is poorly known. The monotypic ''Angka hexops'' has only six eyes, with the posterior median eyes missing. It is up to 15 mm long in both sexes.Murphy, Frances & Murphy, John (2000). ''An Introduction to the Spiders of South East Asia''. Kuala Lumpur ...
