Pseudotyrannochthoniidae
Pseudotyrannochthoniidae is a family of pseudoscorpions, belonging to the superfamily Chthonioidea. It is one of the most primitive living groups of pseudoscorpions and contains fewer 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.
