Araneoidea
The Araneoidea or araneoids are a taxon of araneomorph spiders, originally treated as a superfamily. As with many such groups, its circumscription has varied; in particular some families at one time moved to the Palpimanoidea have more recently been restored to Araneoidea. A 2014 treatment includes 14 families, with the araneoids making up about 26% of the total number of known spider species.
