Avicularioidea
Avicularioidea is a clade of mygalomorph spiders, one of the two main clades into which mygalomorphs are divided. It has been treated at the rank of superfamily.Taxonomy
The division of Mygalomorphae into two clades, Atypoidea and Avicularioidea, has been established in many studies. Avicularioidea has been treated as a superfamily, although other authors have placed superfamilies, such as Theraphosoidea, within Avicularioidea. The name is based on the family name "Aviculariidae", a junior synonym of Theraphosidae, ultimately deriving from the genus Avicularia.
The Atypoidea retain some vestiges of abdominal segmentation in the form of dorsal tergites; the Avicularioidea lack these. Relationships within the Avicularioidea are not settled as of 2018. Some established families have been shown not to be monophyletic. In 2018, the family Hexathelidae was split up, and three new families created within the Avicularioidea: Atracidae, Macrothelidae and Porrhothelidae. Further changes are possible in future.Families
The families included in the Avicularoidea as of 2018 are:
Plus the extinct family Fossilcalcaridae and the incertae sedis genera Cretamygale and Rosamygale.
