Araneoidea
The Araneoidea or araneoids are a group 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 the Araneoidea. A 2014 treatment includes 14 families, with the Araneoidea making up about 26% of the total number of known spider species.
==Taxonomy==
The table below shows some alternative circumscriptions between 1986 and 2014.
Many of the differences in circumscription concern the relationship between the Araneoidea and the Palpimanoidea. In 1984, Raymond R. Forster and Norman I. Platnick proposed that some groups previously considered araneoid actually belonged in the distantly related Palpimanoidea, including the families Holarchaeidae, Micropholcommatidae, Mimetidae and Pararchaeidae. Subsequent phylogenetic studies have rejected this proposal, firmly placing the Holarchaeidae, Micropholcommatidae (as the subfamily Micropholcommatinae of the Anapidae), Mimetidae and Pararchaeidae in Araneoidea.〔
Two families in the table above are placed elsewhere, the Archaeidae in the Palpimanoidea, the Nicodamidae as the sister to the Araneoidea (see the cladogram below).
