Taxonomic contribution to the knowledge of the oribatid mite family Epimerellidae (Acari, Oribatida, Oppioidea)

A new species of the genus Epimerella (Oribatida, Epimerellidae), E. kalmykorum n. sp., is described, based on materials collected from the reed debris in the bank of the salty Manych-Gudilo Lake in the Republic of Kalmykia, Russia. The morphology of gnathosoma and the identification of leg setae and solenidia are given for the first time for any representative of Epimerellidae. Besides, Enisella turcica Ayyildiz and Luxton, 1989 is first found in Crimea (on the shore of the saline Sivash Lake). Generic diagnoses for Epimerella Kulijev, 1967 and Enisella Ayyildiz and Luxton, 1989 are revised. An identification key, distribution and habitats of all known representatives of Epimerellidae are presented.
