Badumna is a genus of intertidal spiders that was first described by Tamerlan Thorell in 1890.[5] 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".[6]

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.[7]

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.[8] B. insignis has also been found in Japan, though it is thought it was introduced.[7]
