Definition

Noun A minute, pale, book scorpion species, scientifically named Chelifer cancroides. It is a very small arachnid, not a true scorpion, that is occasionally discovered among old books, papers, or in stored food products. It is harmless to humans and feeds on other tiny arthropods like booklice and mites.

Usage

The term is used specifically as the common name for this particular species of pseudoscorpion. It is a formal, scientific, and highly specific term.

Examples

• The archivist found a Chelifer cancroides living in the binding of the 18th-century manuscript.
• Under the microscope, the Chelifer cancroides was observed capturing a booklouse with its pincers.
• These Chelifer cancroides are beneficial, as they help control pest populations in libraries and archives.

Advanced Usage

• The species name means "crab-like" in Latin, referring to its sideways walking motion and pincers, which are reminiscent of a crab's claws.
• In entomology and archival science, the presence of Chelifer cancroides can be an indicator of a micro-habitat suitable for other paper-feeding pests.
