| abstract | The present paper deals with the members of oribatid mites of the genera Zygoribatula and Peloribates from Central Asia. Two new species, Zygoribatula semicirculata sp.nov. and Z. mongolica sp.nov., collected from dry steppe and mountain-steppe habitats in eastern Kazakhstan and eastern Mongolia, are decribed on the basis of adults. In addition, supplementary descriptions and illustrations of four known species, Zygoribatula glabra (Michael, 1890), Z. propinqua (Oudemans, 1902), Peloribates robustus Grishina, 1981 and P. pilosus Hammer, 1952 collected from southern Russia and different regions of Mongolia are given. Data on ecology and biogeography of all studied species as well as other species of Zygoribatula and Peloribates recorded in the Central Asian region are discussed. |
