Latrodectus tredecimguttatus

Latrodectus tredecimguttatus, sometimes known as the Mediterranean black widow, the European black widow, or the steppe spider, is a species in the genus Latrodectus (widow spiders). It is commonly found throughout the Mediterranean region, ranging from Portugal to southwest and central Asia, hence the name. Specimens from central Asia are also known by the binomial name Latrodectus lugubris; that name, however, is now considered improper, though it is still commonly found in the literature. Latrodectus tredecimguttatus was previously considered a Latrodectus mactans subspecies.
