Club Fellow discovers two new Pseudoscorpion species in Grand Canyon Cave

In a small cave on the north rim Grand Canyon, Dr. Jut Wynne FN’06 and colleagues discovered two species of cave-adapted false scorpions and subsequently identified them as unique to science—Hesperochernes bradybaughii and Tuberochernes cohni. Originally collected on expedition in 2005 and 2007, Wynne and his co-author described both species as new after a comparative analysis of all similar species. “One of the species had a thickened pair of legs and a mound on the pincer, while another had a much deeper pincer than other pseudoscorpions — qualifying each as distinct,” explained Dr. Mark Harvey, lead author on the paper. On top of this, Jut also collected another pseudoscorpion species, Larca cavicola, on two expeditions with Club Flag #52 in 2008 and 2009, some 160km to the west of its type locality, thereby extending its known range and contributing to our understanding of this species through his work.

You can learn more about Jut’s discovery in this news feature in Live Science, while the paper has been published in the latest issue of the Journal of Arachnology.
