	Eratigena ''Eratigena'' is a genus of spider in the family Agelenidae. Most of its species were moved from the genus ''Tegenaria'' in 2013. Which is what this genus is named after, being an anagram of ''Tegenaria''. Two species that frequently build webs in and around human dwellings are now placed in this genus. ''Eratigena agrestis'' is the hobo spider, native to Europe and Central Asia, introduced to North America. ''Eratigena atrica'' is the giant house spider, native to Europe and also introduced into North America. Description They are medium to large spiders. Two symmetrical dark bands are present dorsally on the carapace, which can be serrated (as pictured) or reduced, usually to three or four conspicuous triangles. They also have plumose hairs on the carapace, legs, and opisthosoma. Their rows of eyes are only slightly curved, in either direction. Taxonomy Phylogeny Species now placed in the genus ''Eratigena'' were previously placed in ''Tegenaria'' and ''Malthonica''. In 2013, ...

picture info	Spiders Described In 1971 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 ...
