Rove beetle (Coleoptera, Staphylinidae) fauna in Southern tundra of Western Taimyr [Russian]

摘要

In the basin of the upper Lower Agapa River (western Taimyr, southern taiga subzone), 41 species (10 subfamilies, 20 genera) of Staphilinidae beetles were found. The Omalinae subfamily includes 13 species (9 genera), Aleocharinae, 13 (3), Tachyporinae, 5 (2), and Steninae, 4 (1). Each family of Proteininae, Xantholininae, Oxytelinae, Staphylininae, Paederinae, and Euaesthetinae is represented by one species. According to the pattern of geographical distribution, the found species are referred to holarctic (34), transpalearctic (5), Siberian (55), and European-Siberian (3% of the species) ones. The proportion of landscape-zonal staphilinid groups in the area investigated is typical for the southern tundra subzone. Arctoboreal (32%), arctic-boreal-monition (17) forms predominate in the fauna, as well as species characteristic of the taiga zone (20), arctic (20%), and polyzonal ones. The majority of species inhabits intrazonal areas; only 7 species represent zonal communities.
