A new cavernicolous Parobisium Chamberlin 1930 (Pseudoscorpiones: Neobisiidae) from Yosemite National Park, U.S.A

Scientists have identified a new species of troglobiotic pseudoscorpion, Parobisium, within two granite talus caves in Yosemite Valley, marking only the second such discovery from North American granite talus caves. This blind species, distinguished by its anterior pair of pale eyespots lacking a tapetum, is common within its known habitat but has not been found elsewhere despite extensive surface and shallow cave searches. The study provides a taxonomic key for the genus in the U.S., highlighting the potential for further subterranean fauna discoveries in undersampled regions. The research underscores the biodiversity of Yosemite National Park's caves, suggesting that granite talus slopes may harbor unique and unexplored troglobiotic species.
