Crossopriza lyoni (Blackwall, 1867) is a widespread, pantropical spider known for its very long legs, squarish abdomen, and close association with human structures. It is harmless to humans and often considered beneficial because it preys on mosquitoes and other small arthropods. The original range of C. lyoni is unknown and they have been introduced into different parts of the world accidentally and are now pantropical in distribution. It was the first time reported from South Africa in 2009 from the Tshwane Market where they were regarded as a problem due to the large amounts of unsightly webs they construct on the walls. The presented status and distribution in South Africa is discuss, with notes on the general morphology and notes on their lifestyle.
