Parobisium yosemite, or the Yosemite cave pseudoscorpion, is a species of pseudoscorpion in the family Neobisiidae.[1] A troglobite, the pseudoscorpion inhabits talus caves, formed by voids between boulders, in Yosemite National Park.[2]
The species is endemic to granite talus caves in Yosemite National Park in California, United States.[3] The type specimens were found in two caves less than 0.5 kilometres (0.31 mi) within a single scree. As the talus caves it inhabits are likely only a few hundred years old, it is thought that the pseudoscorpions migrate between different talus slopes and caves.
Description
Like other troglofauna,[4] P. yosemite is blind with absent posterior eyes and a lack of a tapetum lucidum, and displays unusual pigmentation.[2] The pseudoscorpion is potentially the first North American troglobite documented in a talus cave.[3]
