Editing Mygalomorphae (section)

===Historical classification===
In 1802, [[Charles Athanase Walckenaer|C. A. Walckenaer]] separated mygalomorph spiders into a separate [[genus]], ''Mygale'', leaving all other spiders in [[Araneus|''Aranea'']]

In 1985, [[Robert Raven]] published a monograph of the Mygalomorphae in which he proposed an internal classification for the Mygalomorphae, based on morphological features. Opatova ''et al''. (2020) commented "In short, much of today's classification scheme dates back to Raven (1985)".<ref name=Opat20/> Raven used various compound ranks, such as "gigapicoorder" and "hyperpicoorder". Ignoring these unusual rank names, his classification can be shown diagrammatically:<ref name=Rave85/>

Subsequent research, largely based on [[Molecular phylogenetics|molecular phylogenetic]] studies, has not upheld some of Raven's groupings. In particular his primary division between Tuberculotae and Fornicephalae has been replaced by a very different division between Atypoidea (expanded from Raven's Atypoidina) and Avicularioidea, which has no counterpart in his system. As another example, the families Mecicobothriidae and Microstigmatidae, which Raven placed in Mecicobothrioidina (a "gigapicoorder"), are now placed very far apart in the Atypoidea and Avicularioidea respectively. Other groups, such as Crassitarsae and Domiothelina, are more recognizable, allowing for some changes in family [[Circumscription (taxonomy)|circumscriptions]].<ref name=Opat20/>
