EREMAEIDAE (ACARI: ORIBATIDA) OF NORTH AMERICA
Abstract The oribatid family Eremaeidae is represented in North America by two genera, Eremaeus and Eueremaeus , both widely distributed throughout the Palaearctic and Nearctic regions. In North America species in both genera are found in moist to arid habitats from New Mexico to the High Arctic. Re...
