Latrodectus is a broadly distributed genus of spiders informally called the widow spiders, with several species that are commonly known as the true widows. This group is composed of those often called black widow spiders, brown widow spiders, and similar spiders.
==Diversity== A member of the family Theridiidae, this genus contains 34 species, which include several North American "black widows" (southern black widow Latrodectus mactans, western black widow Latrodectus hesperus, and northern black widow Latrodectus variolus). Besides these, North America also has the red widow Latrodectus bishopi and the brown widow Latrodectus geometricus, which, in addition to North America, has a much wider geographic distribution.
