Annotation:

Two new species of oribatid mites of the genus Epidamaeus are described from larch and birch forests in Central Mongolia. The first new species, Epidamaeus crassisensillatus sp.n. can be distinguished from the closely related species by having a relatively thick and expanded sensillus, the structure of ventral enantiophyses, the pres-ence of fewer setae on the femur II and tarsus IV, and the smaller body size. The second new species, E.brevisetosus sp.n. can be distinguished from its congeners by the character of notogastral setae and sensillus, the complete absence of the ventral enantiophyses E2, F a n d discidium, the different number of setae on femora II-IV, tarsi II-IV, and smaller body size.
