is a venomous spider which can invade peridomestic environments where it lives on insects. It may cause painful bites, but not as painful as for some other members of this genus. The species is believed to be native to Africa. It is now widely distributed in tropical and subtropical regions, apparently through human trade activities. It has been recorded from North America since 1935 and is found across the southern parts of the United States. A female can live for several years. Its body of is 1-2 cm long, up to 3 cm including the legs. Males are about half the size. The colour varies from light brown to black, often with elaborate patterns on the back of the abdomen. The hourglass pattern on the ventral side is common in all species of this genus. Egg sacks have characteristic spiny projections.
