White-tailed spider : ウィキペディア英語版 | White-tailed spider
White-tailed spiders are spiders native to southern and eastern Australia, and so named because of the whitish tips at the end of their abdomens. Body size is up to 18 mm, with leg-span of 28 mm. Common species are ''Lampona cylindrata'' and ''Lampona murina''. Both these species have been introduced to New Zealand. White-tailed spiders are vagrant hunters that seek out and envenom prey rather than spinning a web to capture it; their preferred prey is other spiders. They are reported to bite humans; effects include local pain, a red mark, local swelling and itchiness; rarely nausea, vomiting, malaise or headache may occur. Ulcers and necrosis have been attributed to the bites, but a scientific study by Isbister and Gray (2003) showed these had other causes, mostly infections. The study of 130 white-tailed spider bites found no necrotic ulcers or confirmed infections.〔 ==Taxonomy==
Ludwig Carl Christian Koch described ''Lampona cylindrata'' in 1866 and ''Lampona murina'' in 1873. The genus name comes from the Latin ''lampo'' which means shine. The species name ''cylindrata'' refers to the cylindric body shape, while ''murinus'' means "mouse-gray" in Latin.〔
