Latrodectus geometricus Koch - (brown widow spider)
This is a venomous spider which occasionally invades peridomestic environments where it lives on insects. It may cause painful bites, but not as painful as for some other members of this genus. The species is believed to be native to Africa. It has been recorded from North America since 1935 and is now found across the southern parts of the United States as well as in most other American countries. It has also spread to other tropical and subtropical regions, apparently through human trade activities. For example, it has been introduced into several Pacific Islands since 2006 (Marie & Vetter, 2015)
