SAN FRANCISCO (August 17, 2012) — A team of scientists and cave conservationists discovered a relatively huge, unique spider in caves and forests of the Pacific Northwest. The novel combination of evolutionary features in this spider, Trogloraptor, compelled them to recognize a new family. A study of the new family and its evolutionary and conservation significance was published in the open access journal ZooKeys on August 17.
The forests of the coastal regions from California to British Columbia are renowned for their unique and ancient animals and plants, such as coast redwoods, tailed frogs, mountain beavers—and now, a large, newly discovered spider. Trogloraptor (or “cave robber”) is named for its cave home and spectacular, elongate claws. It is a spider so evolutionarily special that it represents not only a new genus and species, but also a new family (Trogloraptoridae). Even for the species-rich insects and arachnids, to discover a new, previously unknown family is rare.
A team of citizen scientists from the Western Cave Conservancy and arachnologists from the California Academy of Sciences found these spiders living in caves in southwest Oregon. Colleagues from San Diego State University found more in old-growth redwood forests. Charles Griswold, Curator of Arachnology, Joel Ledford, postdoctoral researcher, and Tracy Audisio, graduate student, all at the California Academy of Sciences, collected, analyzed, and described the new family. Audisio’s participation was supported by the Harriet Exline Frizzell Memorial Fund and by the Summer Systematics Institute at the Academy, which is funded by the National Science Foundation.
