Arachnophobes may be alarmed to learn that scientists have identified 55 new species of Australian wishbone spiders, highlighting the incredible biodiversity found in this region. This study is particularly important for understanding national biodiversity.
Coming from the same group as tarantulas and funnel-web spiders, wishbone spiders dig burrows and line them with silk to help them catch prey effectively. These burrows are uniquely shaped like a wishbone or the letter Y, with one leg shorter than the other, showcasing the remarkable adaptations of these spiders in their national habitat.

Only one leg of the wishbone spider reaches the surface, providing an entrance to the burrow while the other remains hidden underground, believed to provide extra protection for the spider.
Found across mainland Australia, scientists from Queensland Museum, Western Australian Museum, and the University of Western Australia have collaborated on a groundbreaking two-year study of these arachnids, emphasizing the importance of national scientific research.
The project involved extensive fieldwork in some of Australia’s more remote ecosystems, where several species of wishbone spider reside, as well as cutting-edge molecular techniques used to study these fascinating spiders.

Now, these dedicated researchers have published a landmark research paper that includes the description of 55 species new to science, contributing significantly to our national understanding of biodiversity.
Some additions to the Aname genus include A. mulgana, named for the Mulga Lands of south-western Queensland, and A. lawrenceae, named in honor of the study’s project manager Melinda Lawrence. These discoveries make wishbone spiders one of the most diverse and widely distributed groups in Australia.
However, lead author Dr. Jeremy Wilson noted that more than half of the Aname genus of wishbone spiders found in Australia remains undescribed, with many species only located in remote or arid parts of the country, underscoring the need for continued research in the national context.

Dr. Wilson expressed that the two-year study has led to “amazing observations” about the secretive spiders’ burrowing habits, as well as the physical differences between species. This research serves as a reminder of how much there is still to learn about our unique biodiversity, ensuring that future generations can appreciate the incredible diversity of life that calls Australia home.
