Fornicephalae

The Fornicephalae are an infraorder of mygalomorph spiders, consisting of eight families with ca. 70 genera and 700 species.

  • Atypoidea ( Antrodiaetidae and Atypidae)
  • Cyrtauchenioidea
  • Idiopoidea
  • Migoidea ( Actinopodidae and Migidae)

They are opposed to the Tuberculotae, which make up the rest of the Mygalomorphae.

However, according to (Goloboff, 1993), neither group appears to be monophyletic.
