Paintings of Araneus angulatus from Svenska Spindlar of 1757, the first major work on spider taxonomy. Spider taxonomy is the part of taxonomy that is concerned with the science of naming, defining and classifying all spiders, members of the Araneae order of the arthropod class Arachnida, which has more than 48,500 described species. [1]
Spiders (order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, [2] and spinnerets that extrude silk. [3] They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms .
The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of web pages in 2000, created by Norman I. Platnick of the American Museum of Natural History.

The Mesothelae are a suborder of spiders (order Araneae). As of April 2024, two extant families were accepted by the World Spider Catalog, Liphistiidae and Heptathelidae. Alternatively, the Heptathelidae can be treated as a subfamily of a more broadly circumscribed Liphistiidae. There are also a number of extinct families.
Mysmenidae is a spider family with about 180 described species in seventeen genera. The family is one of the least well known of the orb-weaving spiders because of their small size (0.76 to 3 mm (0.03 to 0.12 in)) and cryptic behaviour.
They cooperatively capture and feed on prey caught in the web. Upon reaching sexual maturity, the young spiders leave the web, move a short distance away and exhibit solitary behavior. [3] The genus exhibits sexual dimorphism, males range in size from 3.5 to 4 mm while females are slightly larger ranging from 4 to 4.5 mm.
The genus Argiope includes rather large spiders that often have a strikingly coloured abdomen. These spiders are distributed throughout the world. Most countries in tropical or temperate climates host one or more species that are similar in appearance. The etymology of Argiope is from a Latin word argentum meaning silver. [2]
