KEY WORDS: Spiders, Fennoscandia, new record, Perregrinus deformis. КЛЮЧЕВЫЕ СЛОВА: Пауки, Фенноскандия, новая находка, Perregrinus deformis. ABSTRACT. The Siberian-Nearctic linyphiid spider Perregrinus deformis (Tanasevitch, 1982) is recorded from Fennoscandia for the first time. The vicinity of Murmansk is the westernmost locality of species known distribution in the Palaearctic Region. On the basis of new data, the species displays a Fennoscandian-Siberian-Nearctic range. РЕЗЮМЕ. Считавшийся ранее сибирско-неарктическим, вид Perregrinus deformis (Tanasevitch, 1982) впервые найден в Фенноскандии, в окрестностях Мурманска. На сегодняшний день это самая западная, из известных, точка распространения вида в Палеарктике. Согласно новым данным, ареал вида может быть охарактеризован как Фенноскандинавско-сибирско-неарктический. MBS-9 stereomicroscope with eyepiece-micrometer and given in mm. The material is deposited in the Zoological Museum of the Moscow State University, Russia.

Results
An adult female of P. deformis was collected (Fig. 2A): its total length 1.6; carapace 0.8 long, 0.6 wide, pale grey; abdomen 0.9 long, 0.6 wide, dark grey. Legs yellowish. The epigyne is typical for the species, as shown in Fig. 2B. P. deformis was originally described from the Polar Urals [Tanasevitch, 1982]. Later on it was recorded from Siberia [Mikhailov, 1997; Marusik et al., 2000; Tanasevitch, 2007; Marusik & Eskov, 2009], Mongolia and China [Eskov, 1994; Song et al., 1999], and from Canada [Koponen, 1994; Dondale et al, 1997; Paquin et al., 2010]. To date, the westernmost locality of the species distribution has been Indiga situated in the Malozemelskaya tundra, Arkhangelsk Area [Tanasevitch & Koponen, 2007]. As P. deformis have never earlier been found in well-studied Fennoscandia, it is safe to assume that species is either quite rare there or was confused with another species. On the basis of the new data, the species displays a Fennoscandian-Siberian-Nearctic range.

Introduction
Despite the spider fauna of the Kola Peninsula is well-studied and numbers 228 species [Tanasevitch, Kamayev, 2010], new findings are still possible. The linyphiid spider Perregrinus deformis (Tanasevitch, 1982) earlier known from Siberia and the Nearctic Region has been found from the vicinity of Murmansk. The sampling site (68?54.356' N, 033?01.194' E) is situated on the West coast of Kolskiy Gulf (Fig. 1), near the road Murmansk Pechenga. The studied area is under anthropogenic impact and differs from the adjacent forests in reduced plant diversity. Its plant community consists of young Betula stands (hight 0,5 1,0 m) with Vaccinium myrtillus, V. vitis-idaea, V. uliginosum, Empetrum sp., Calluna vulgaris and Ledum palustre, the litter is mostly absent, moss and lichens are scarcely available. The studied material was collected by pitfall traps (with 4% formaldehyde) during the period of 1623 May 2010. All the measurements were made by using
