At present oribatid fauna of the Russian Far East exceeds 600 species. Oribatid number in
soils of different nature zones is found to depend on area moistening conditions, amount of
organic matter transported into the soil and its decomposition rate. Each soil type produces
specific composition of oribatid faunistic complexes and specific ratios of oribatid life forms.
The least studied in the Far East are its northern territories, namely Chukotka (known over 70
species) and Magadan region (20 species). Standard observation reveals 15 ? 40 species in
one biotope. It is more than in the arctic and typical tundra of Europe and comparable with south
European tundra sub-zones. Holarctic and palaearctic species (about 60%) and species with
Angara and Bering links dominate here. V. Behan-Pelletier described from that area a new
genus Asperemaeus and 10 species of genera Niphocepheus, Proteremaeus, Epidamaeus,
Ametroproctus. It indicates a highly diverse oribatid fauna in the Far East North. In Kamchatka
region 110 oribatid species are registered, which have mostly palaearctic and east-Siberian
links. The number of Bering and less specific species is reduced here and endemic species
are practically not found. In Sakhalin region (with little over 200 species known) most species
diversity is observed in the south-east of the island, where remnants of formally dominating
coniferous - broad-leaved forests still exist. Here the biggest number of south palaearchearctic
species is also registered. In the north of the island boreal elements in fauna composition
increase. The Kuril Islands (especially in the southern Islands of Kunashir and Shikotan) are
characterized with high diversity of species (about 230), polydominant communities, a big number
of palaearchearctic species, presence of relict elements (especially under the broad-leaved
forests and near warn springs), a high percentage of specific and endemic species. To the
north, closer to the archipelago species variety decreases and boreal species prevail. Most
diverse and well studied is the oribatid fauna of the continental Far East south, i.e. of Khabarovsky
(about 300 species) and Primorsky krais (over 250 species). The basis of oribatid fauna is
formed with species belonging to the boreal faunistic complex, especially in mountainous areas
and in the north of Primorsky Krai. The palaearchearctic complex (as proposed by Semenov-
Tyan-Shansky, 1935), based on species of south-east origin, constitute 35% in favorable
conditions. These species are most fully represented in soils of broad-leaved and coniferousbroad-
leaved forests in the south of Khabarovsky Krai and black coniferous-broad-leaved forests
of Primorsky Krai. The majority of species are those dominantly present in the Sakhalin and
Kuril Islands and Japan. Steppe Mongolian elements penetrate dry meadows in Primorsky Krai
and steppe low-mountain hills in Khabarovsky Krai, their number increasing towards the west
and due to landscape xerophytization. Generally speaking oribatid fauna of the Russian Far
East is very diverse and is composed of many biogeographic elements, which are characterized
