[1] Two medically important spider genera have a worldwide distribution—Latrodectus and Loxosceles. Others have a limited distribution.

Female widow spiders are typically dark brown or a shiny black in colour when they are full grown, usually exhibiting a red or orange hourglass on the ventral surface (underside) of the abdomen; some may have a pair of red spots or have no marking at all.
They have been deemed to be the world's most dangerous spiders on clinical and venom toxicity grounds, [119] though this claim has also been attributed to the Brazilian wandering spider (genus Phoneutria). [124] There were about 100 reliably reported deaths from spider bites in the 20th century, [125] compared to about 1,500 from jellyfish ...
