Badumna is a genus of intertidal spiders that was first described by Tamerlan Thorell in 1890. They are harmless spiders that can be found around human structures and buildings. The most well-known species is B. insignis, also known as the "black house spider" or "black window spider".




Description


They are medium to large cribellate spiders. The carapace is pale brown to a darker brown in color, with long or small brown hairs being found besides smaller white hairs. The opisthosoma has a dark striping or spotting.




Distribution


Most of the species are considered to be endemic in the Indo-Australian region, but some have been introduced elsewhere. B. longinqua is the only species introduced to North America, now found in urban areas along California's Pacific coast. B. insignis has also been found in Japan, though it is thought it was introduced.
