Seventeen habitats of Tyulenii and Nordovyi Islands in the northwestern part of the Caspian Sea and the Bryanskaya Kosa Cape on the Caspian coast of Daghestan were examined. Thirty six species of oribatid mites were identified; seven of them were recorded for the first time from the Caucasus and eight species, from Daghestan. Oribatula (Zygoribatula) caspica sp. n. is described. The identity of Peloribates pilosus Hammer, 1952 sensu Pérez-Íñigo, 1974 and the original description is discussed. A new name, Peloribates perezinigoi nom. n., is proposed for specimens described by Pérez-Íñigo (1974).
