Diversity [1]
2 genera, 5 species

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. [2]

Contents

In 2018, the family Halonoproctidae was split off from the Ctenizidae. [3] A further genus, Stasimopus , was split off into its own family, Stasimopidae, in 2020. [3] [4] The family currently consists of two genera and five species. [1]

Etymology

The name derives from Greek κτενὶζεινktenizein, meaning "combing" or "cleaning", referring to their behaviour of cleaning continuously, and the suffix "-idae", which designates belonging to a family.[ citation needed ]

Taxonomy

The family Ctenizidae was first described by Thorell in 1887, being based on the genus Cteniza . [3] Since the advent of molecular phylogenetics and its application to spiders, the family has been progressively dismantled; [5] the World Spider Catalog lists over 100 genera formerly placed in Ctenizidae but now transferred to other families. [3] The Halonoproctidae were split off in 2018, leaving only three genera. Even so, the family was not monophyletic, since Stasimopus is not in the same clade as the other two genera, according to a 2018 study (the three genera left in the Ctenizidae at that time are shaded in yellow): [5]

Stasimopus

Heteromigas (Migidae)

Idiops (Idiopidae)

Myrmekiaphila (Euctenizidae)

Cteniza

Cyrtocarenum

Halonoproctidae

In 2020, a large scale molecular phylogenetic study confirmed the placement of Stasimopus outside the clade consisting of Cteniza and Cyrtocarenum, and transferred it to its own family, Stasimopidae. [4] This placement is accepted by the World Spider Catalog as of February 2022. [3]

Genera

As of February 2022, the World Spider Catalog accepted only two extant genera: [3]

Extinct genera

Distribution and habitat

The two genera of Ctenizidae are found in Europe and Turkey, particularly in France and Italy. [3] Like many other mygalomorphs, Cteniza have highly localized distributions. This results in clumps of spider burrows a short distance from their maternal burrows, resulting in a dense cluster of spiders surrounding a large female. [7]

The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3,000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to their creation of 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.

Cyclocosmia is a genus of mygalomorph trapdoor spiders in the family Halonoproctidae, first described by Anton Ausserer in 1871.

<span class="mw-page-title-main">Bipectina</span> Clade of spiders

Bipectina is a clade of avicularioid mygalomorph spiders first proposed by Pablo A. Goloboff in 1993, based on a morphological cladistic analysis. The clade was marked by a number of morphological features, and in particular by the presence of two rows of teeth on the superior tarsal claws of the legs of both sexes, meaning that the claws were bipectinate. The clade was supported by some subsequent analyses, although not all. A major phylogenetic study in 2020 upheld the monophyly of the clade, which contained 19 of the 25 accepted families of the Avicularioidea.

Raven characterized the clade by a number of shared features, including the domed apical segment of the posterior lateral spinnerets. The clade has been supported to some degree by subsequent molecular analyses, although with a somewhat different composition.
