Usually abundant in forest leaf litter, can be extracted using a home-made Berlese Funnel HERE.
This specimen was removed from the leg of a fly; pseudoscorpions are phoretic.
Microscope slide temporary mount. Length: 3.6mm from tip of chelicerae to end of abdomen.

Top image: Whole specimen. Note the Pedipalps - large pincerlike appendages have poison glands opening at tips for capturing and killing prey.

Bottom image: Close-up of Chelicerae
At the front of the body are the Chelicerae - small claspers for holding prey while feeding. The moveable outer finger has a spinneret near the tip involved in silk production.

Bottom Image: Nikon 10x objective, 160mm bellows extension; 12 frames at 0.02mm, HF 4.1. 1st test of my new set-up using Nikon Focusing Block HERE

Many refs. to Pseudoscorpions on Google including HERE
