Idioctis parilarilao is a species of mygalomorph spider in the Barychelidae family. [1] The species name parilarilao also forms a part of its alternative name, the parilarilao trapdoor spider. In the Paiwan language, parilarilao means "living at the end of Taiwan".
Wafer-lid spiders are generally large and range in color between light brown and black. Their eyes are placed in two rows, either in a rectangular position or with the back row wider apart. [4] They lack the thornlike spines on tarsi and metatarsi I and II (the two outermost leg segments) found in true trapdoor spiders .
Ctenizidae (/ ˈ t ə n ɪ z ə d iː / tə-NIZZ-ə-dee) [2] 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 Nemesiid
Like other trapdoor spiders, Eucteniza species construct burrows in the ground with a hinged lid, from which they wait to ambush passing prey. Burrows and prey have been studied in E. relata, and other species are believed to have similar behavior. The burrow consists of an un-branched tube, lined with silk and soil, ranging from 7 to 25 cm (2. ...
Trapdoor spiders in New Zealand do not have silk trip lines, but instead sense the vibrations of the prey outside the trapdoor. The spiders have been observed, perching just behind the trap door, ready to strike. Occasionally the spider will leave the burrow completely to chase the prey, however this wasn’t the preferred behaviour. [1]
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 ...
Missulena bradleyi. Though they resemble most genera of the infraorder Mygalomorphae, they can be easily distinguished by the large pair of chelicerae, as well as by the placement of two small eyes in the centre of the head and three at each side, whereas in all other trapdoor spiders the eyes are grouped in a mound at the centre of the head.
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
