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.

[12] Those Cambridgea that do build webs run along the underside of the mainsheet rather than along the top as some sheet-web spiders do (e.g ...
