	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 ...

	Euctenizidae The Euctenizidae (formerly Cyrtaucheniidae subfamily Euctenizinae) are a family of mygalomorph spiders. They are now considered to be more closely related to Idiopidae. Etymology The name comes from the Greek prefix (''eu-''), meaning "valuable" or "good", which had been thought that the family Ctenizidae possess these traits.Bond, J. E., B. E. Hendrixson, C. A. Hamilton & M. Hedin. (Bond et al., 2012b) - ''A reconsideration of the classification of the spider infraorder Mygalomorphae (Arachnida: Araneae) based on three nuclear genes and morphology'' 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 of the species is poorly known. Distribution The family occurs almost exclusively in the United States and Mexico. Common U.S. genera include ''Myrmekiaphila'', ''Aptostichus'' and '' Promyrmekiaphila''. Genera , the World Spider Catalog accepts the fo ...

picture info	Spiders Described In 1895 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 th ...
