Abstract

A new species of pseudoscorpion, Albiorix anophthalmus, is described from Arkenstone Cave, Pima Co., Arizona. It is highly modified for life in the cave, being larger and more slender than any other known species in the genus and the only known species without eyes. Descriptions of the epigean (surface) and hypogean (cave) environments are provided. Observations on the biology and ecology of A. anophthalmus also are presented. /// Se describe una nueva especie de pseudoescorpión, Albionx anophthalmus, de la cueva Arkenstone, del condado Pima en Arizona.
