Chelifer cancroides, the house pseudoscorpion, is a species of pseudoscorpion. It is cosmopolitan, synanthropic and harmless to humans.[1]

Subspecies[]

There are two subspecies:[2]

Description[]

Chelifer cancroides measure 2.5–4.5 mm (0.098–0.177 in) in length. The pedipalps are very long,[3] measuring 7–9 mm (0.28–0.35 in) when extended. The body is teardrop-shaped and has a rich mahogany color. The abdomen has 12 segments, only 10 of which are easily visible. The cephalothorax has one pair of eyes.[1]

Reproduction[]

Males maintain small mating territories, few centimeters in size. When a female enters the territory, the male initiates a mating dance and eventually deposits a spermatophore, which is then picked up by the females. Fecundity is 20–40 eggs. The development from egg stage into maturity takes 10 to 24 months and involves three molts;[1] molting may involve building a silk nest.[3] They usually live three or four years.[1]

Distribution[]

Chelifer cancroides has been observed in North America, Europe, Africa, and Australia.[4]
