Chthonioidea Explained

The Chthonioidea are a superfamily of pseudoscorpions, representing the earliest diverging and most primitive living pseudoscorpions. The superfamily contains two families.^[1]

• Pseudotyrannochthoniidae — worldwide (c. 5 genera, 50 species)
• Chthoniidae — worldwide (40 + genera, 600+ species)

Some authors consider the genus Lechytia to be in its own family Lechytiidae, rather than to reside in Chthoniidae.^[2]
