ABSTRACT. Data on the fauna of the oribatid mites of the North-Eastern Altai are firstly presented. Currently, 181 species belonging to 109 genera, 58 families and 30 superfamilies are detected. Two species were firstly recorded for the Russian fauna: Metrioppia zlotini Krivolutsky, 1971 and Dolicheremaeus montanus Krivolutsky, 1971; 82 — for the Russian part of the Altai. The largest taxonomic wealth was recorded in the superfamilies Ceratozetoidea (5 families, 20 genera and 39 species), Gustavioidea (6, 11 and 19), Oripodoidea (6, 10 and 18), Crotonioidea (4, 7 and 13), Galumnoidea (2, 4 and 12) and Oppioidea (4, 8 and 10). These six largest taxa account for more than 60% of total species of the oribatid mites of the study territory. In the high-belt gradient, a foothill-low-mountain forest sub-zone has a special status. Due to the optimal hydrothermal regime in terms of the ratio of heat and moisture and the variety of landscapes, the oribatid mites of this belt have the highest values of level, concentration, potential and originality of species richness.
