Pseudoscorpiones

The common name for Pseudoscorpiones is ‘false scorpions’ due to their greatly enlarged claw-like palps resembling that of true scorpions. There are approximately 3,380 described species.

Unlike their scorpion relatives, pseudoscorpions don’t have a ‘tail’ with a sting, although the majority of species do have venom glands in their palps.

They produce silk with the glands situated in the prosoma. This silk is used

to build chambers for:

  • hibernation
  • molting
  • egg laying
About the name

The French name faux-scorpions was created in 1778 and then Latinized to Pseudoscorpiones. The name 'Chelonethi' is also used  as well as ‘draca’ which is an Icelandic word meaning 'a dragon without a tail'.
