Latrodectus mactans, known as southern black widow or simply black widow, and the shoe-button spider, [citation needed] is a venomous species of spider in the genus Latrodectus. The females are well known for their distinctive black and red coloring and for the fact that they will occasionally eat their mates after reproduction.
Bites from Latrodectus occur usually because of accidental contact with the spiders. The species are not aggressive to humans naturally, but may bite when trapped. As such, bite incidents may be described as accidents. Reports of epidemics [23] were associated with agricultural areas in Europe in the last two centuries. However the European ...
The genus Latrodectus was erected by Charles Athanase Walckenaer in 1805, for the species Latrodectus tredecimguttatus and Latrodectus mactans. [ 1 ] [ 25 ] Arachnologist Herbert Walter Levi revised the genus in 1959, studying the female sexual organs and noting their similarity across described species.
α-Latrotoxin (α-LTX) can naturally be found in widow spiders of the genus Latrodectus. The most widely known of those spiders are the black widows, Latrodectus mactans. [4] The venom of widow spiders (Latrodectus) contains several protein toxins, called latrotoxins, which selectively target either vertebrates, insects or crustaceans. One of ...

Latrodectus hasselti, the redback spider. The widow spiders (genus Latrodectus), such as the black widow, redback spider, and katipÅ are spiders that carry a neurotoxic venom [18] which can cause a set of symptoms known as Latrodectism. Widow spiders are large, shiny house spiders with relatively spindly legs and deep, globular abdomens.
In most species, only the female spider is capable of effectively delivering the venom to humans as the males have much smaller chelicerae. Although rarely fatal, the symptoms of the bite are often incredibly painful and medical attention is recommended following any Latrodectus species bite, as complications relating to the bite can arise.
