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]
