Amaurobioides are restricted to the spray zone of southern continents, where they live in small, isolated populations and hunt from silk retreats built in rock crevices. A Star BEAST species tree based on ITS1 nuclear and ND1 mitochondrial genes did not support the hypothesis that this unusual niche linked the evolutionary history of these spiders to geological events reshaping Gondwana into present‐day Australia and New Zealand. Instead, it showed that Amaurobioides reached Australia approximately 4.5 Mya and dispersed twice to New Zealand. Approximately 2.37 Mya, spiders from Tasmania colonized the Deep South of the South Island and, approximately 0.38 Mya, those from South Australia colonized more northern regions. Thus, the present study further limits the scope of the Moa's Ark hypothesis of vicariant New Zealand biogeography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
