The southern black widow spider (Latrodectus mactans), a cause of latrodectism
Specialty
Emergency medicine
Latrodectism (/lætrəˈdɛktɪzəm/) is the illness caused by the bite of Latrodectus spiders (the black widow spider and related species). Pain, muscle rigidity, vomiting, and sweating are the symptoms of latrodectism.
There are several spider species all named black widow: southern black widow spider (L. mactans), the European black widow (L. tredecimguttatus), Western black widow spider (L. hesperus), Northern black widow spider (L. variolus). Other Latrodectus that cause latrodectism are the Australian redback spider (L. hasselti), the New Zealand katipō spider (L. katipo) and the South American Latrodectus corallinus and Latrodectus curacaviensis. Several other members of the genus Latrodectus are not commonly associated with latrodectism including the cosmopolitan brown widow (L. geometricus).
