Pseudotyrannochthoniidae is a family of pseudoscorpions, belonging to the superfamily Chthonioidea. It represents the most basal and primitive group of living pseudoscorpions, with less than 100 species in 6 genera. Living members of the group have a strongly disjunct distribution, likely reflecting ancient vicariance, occurring in Australia, Asia, Southern Africa and Madagascar, Western North America and southern South America. Fossils species are known from the Eocene Baltic and Bitterfeld amber, which represent members of extant Asian genera.
