Researchers have identified a new species of tarantula, characterized by vibrant red markings, in Arizona, marking a surprising discovery.

“While new species are often found in remote parts of the world, it’s incredible that these spiders are located in familiar territories, albeit in less accessible areas,” stated Chris Hamilton, an assistant professor at the University of Idaho and a co-author of the study published in ZooKeys. “With the planet currently facing a crisis of species extinction due to human impact, it’s striking how little is understood about the biodiversity of our own environment, even for noticeable and captivating species like tarantulas.”

A news release on August 19 from EurekAlert highlighted this eight-legged discovery. The particular tarantula is primarily gray and black, featuring a striking “fiery red” abdomen.

The fuzzy arachnid, named Aphonopelma jacobii, is the 30th documented species of tarantula in the United States. It was named in honor of Michael Jacobi, who was instrumental in locating several of the first specimens that contributed to identifying this new species.

However, this tarantula could be at risk and may even face extinction due to climate change.

Where was it found?

The tarantula was discovered in the forests of the Chiricahua Mountains located in southeastern Arizona, a region known for enduring “harshly cold winters.”

This mountain range is celebrated for its remarkable biodiversity, as noted in the news release.

There are significant levels of endemism present, indicating a variety of species exclusive to this region.

The mountains are part of the Madrean Archipelago, also referred to as the Madrean Sky Islands.

The “islands” are formed by forested mountain ranges that are separated by deserts and dry grasslands, spanning from the Colorado Plateau through the Rocky Mountains of the southwestern U.S. and into the Sierra Madre Occidental in northwestern Mexico.

Due to evolving in isolation, these mountains have created an environment that has birthed numerous endemic species, resulting in a “mosaic of biodiversity” found nowhere else in the U.S.

Threats to its natural habitat

The natural habitat of this tarantula is under threat due to climate change, according to the news release.

“Recent findings in the Sky Island region indicate that these forests may be forced off the mountains in the coming decades as temperatures rise and precipitation patterns fluctuate,” the release stated. “Species adapted to the cooler, moist mountain tops—like these spiders—will likely face extinction as their ideal habitat disappears.”

According to Brent Hendrixson, co-lead author of the study and professor at Millsaps College, this species is also endangered by:

• Expanded suburban development
• Destructive outdoor activities
• Wildfires

“Additionally, there is a rising concern that these tarantulas may be targeted for the exotic pet trade due to their uniqueness, vibrant colors, and gentle nature,” Hendrixson remarked. “It’s crucial to evaluate the potential implications of unethical collectors on these spiders while assessing the threats to their survival and conservation.”
