The House Pseudoscorpion is a large cosmopolitan species that is frequently observed in houses (
Levi 1948).
Jacobs (2010) provides the following description: "The house pseudoscorpion adult is 3 to 4 millimeters in length and has a rich mahogany color. Its four pairs of legs increase sequentially in length. It has one eye on each side of its cephalothorax (head plus thorax) and a 12-segment abdomen (only ten are easily visible). Overall, the body resembles a teardrop. The pedipalps, located in front of the first pair of legs, are more than twice as long as the legs. When extended, crab-like, they measure 7 to 9 millimeters across."
