Researchers at the University of Idaho have identified a new species of spider in the mountains of northern Idaho and given it a name that pays tribute to the university itself: Hexura vandal .
The spider belongs to a small group of funnel-web spiders related to tarantulas. Until now, only two species in this genus were known, both living hundreds of miles away in the coastal forests and mountains of Oregon and Washington.
Finding a third species so far inland, in the Rocky Mountains near the town of Kooskia, came as a surprise to the research team, led by Arnau Calatayud-Mascarell, Ethan J. Briggs and Chris A. Hamilton. It extends the known range of the genus by roughly 500 kilometres and is the first new taxonomic work done on this group of spiders in almost fifty years.
Associate Professor Dr. Chris A. Hamilton stated, “It’s always exciting when you realize the samples you’ve been looking at are an undescribed new species. This is one of the main reasons we do this job - to document Earth’s incredible biodiversity and expand our foundational biological knowledge of our planet. It just makes it even more exciting when that undescribed diversity can be found in your backyard (figuratively speaking).”
The name is where the story becomes especially local. Rather than a Latin descriptor, the researchers chose “vandal”, which is a direct nod to the university’s own mascot. The nickname dates back to 1917, when student journalist Harry Lloyd McCarty described the men's basketball team's fierce style of play as “vandalizing” their opponents. The name stuck, and the University of Idaho remains the only Division I university in the United States with the Vandals as its mascot.
When discussing how the name was picked, Hamilton said, “It didn’t take very long for the lab to sit down and decide what to name the new species. It was basically, this is really unique because it’s only found in Idaho and it’s not very far (relative) from campus. It’s black (sorry that it’s not black and gold like the school colors!). It’s a predator that attacks. It’s a Vandal.”
The discovery comes with a note of caution. Hexura vandal has so far only been found in a handful of sites within a very small area of forest in Idaho, despite repeated searches nearby. The region faces pressure from logging, and wildfires, which are becoming more frequent, and tend to strike during the spiders’ breeding season. Taken together, these factors have led the researchers to consider the micro-endemic species likely endangered, and they hope the discovery will help build the case for protecting its habitat.
The findings are described in a newly published scientific paper in ZooKeys by the research team, based at the University of Idaho's Department of Entomology, Plant Pathology and Nematology .

University of Idaho , home of the Vandals, is Idaho’s land-grant university and the state’s first Carnegie R1 research institution — a ranking reserved for the top 4% of U.S. universities. From its residential campus in Moscow, U of I serves the state through centers in Boise, Coeur d’Alene, Idaho Falls and McCall, nine research and Extension centers, and Extension offices in 42 counties. With more than 12,000 students, U of I is a leader in student-centered experiential learning, interdisciplinary research, business and community service and global outreach. The Vandals compete as a founding member of the Big Sky Conference and as an affiliate in the Big West and Mountain Pacific Sports Federation.
