Spider families

spider family

Macrothelidae is a family of mygalomorph spiders, split off from the family Hexathelidae in 2018. It contains extant genera, and the extinct Promacrothele.

Lathyidae is a family of spiders established in 2025, comprising small cribellate araneomorph spiders. The family was erected following a comprehensive molecular phylogenetic study that resolved the taxonomic confusion within the "tailor's drawer" family Dictynidae sensu lato.
