On spiders from the tundra zone of the Kola Peninsula, Russia (Arachnida: Aranei)
A checklist of 105 spiders from the tundra zone of the Kola Peninsula is based and compiled on the original collections and on available literature data. Oreoneta sinuosa (Tullgren, 1955) is reported as a new to the Russian fauna. A new synonym is proposed: Lepthyphantes murmanicola Strand, 1913, syn.n. = Oryphantes angulatus (O. Pickard-Cambridge, 1881). Some previous misidentifications are rectified. Faunistic data and the distribution pattern are indicated for each species. For the majority of the recorded spiders, the northern coast of the Kola Peninsula is the northernmost point of their known distributions. The spider fauna of the tundra zone of the Kola Peninsula has a typical boreal face, and is composed of widespread or European boreal/polyzonal species. There are no real Arctic elements found here. The zonal plant communities have the fewest spider species, lack of the specific elements, and are comprised of boreal or ubiquitous species. Intrazonal and anthropogenic communities are much richer, and together with azonal communities serve as a shelter not only for the southern elements, but also for the arcto-alpine species.
