New records of spiders (Aranei) from the Russian Arctic

Abstract

New records of 34 spider species from the Russian Arctic are presented and supplied with detailed descriptions of their habitats. Some misidentifications are corrected, the known patterns of distribution of many species are complemented and newly typified.

Spiders (Aranei) of the typical tundra subzone of the Yugorsky Peninsula, Russia

“…The study of araneofauna of arctic islands from the European Russian sector has started in XIX century, and its history was in detail described by Tanasevitch [2017c]. At present, one species is known from Kolguev Island [Tanasevitch, 2017b], 52 species -from Dolgy Island [Marusik et al, 2016]; 20 and 21 speciesfrom Vaygach Island and Novaya Zemlya Archipelago, respectively [Tanasevitch, 2017c]; the araneofauna of polar deserts of Franz Josef Land Archipelago contains only two species [Bulavintsev, Babenko, 1983].…”

New data on spiders (Arachnida: Aranei) of the Central Yamal Peninsula, with notes on biotopic preferences of the dominant species

“…According to published data, the faunas of the Southern and Northern Yamal include 165 and 36 species, respectively. Total species richness of the whole Yamal Peninsula is at least 200 species [Esyunin, Efimik, 1996;Esyunin, Laetin, 2009;Tanasevitch et al, 2009;Tanasevitch, Rybalov, 2015;Tanasevitch, 2017b].…”

“…region of the Arctic that has been existing in its current state since the beginning of the Late Pleistocene [Rebristaya, 2013]. To date, the spider fauna of the Southern Yamal has been studied the most and, according to expert estimates, includes at least 176 species [Esyunin, Laetin, 2009], while only 38 and 36 species are known for the Central and Northern Yamal, respectively [Holm, 1973;Esyunin, Laetin, 2009;Tanasevitch et al, 2009;Tanasevitch, Rybalov, 2015;Tanasevitch, 2017b].…”

New data on spiders (Aranei) from the Novaya Zemlya Archipelago and Siberian Arctic, Russia

“…After my recent publication [Tanasevitch, 2017a] another few samples from different localities of Siberia's Arctic have become available. Some new records are thus given below.…”

“…Two papers on Arctic spiders have recently been published: a revision of the spider fauna of the Novaya Zemlya [Tanasevitch, 2017b], and a annotated list of new records of spiders from different localities of the continental and insular territories of the Russian Arctic [Tanasevitch, 2017a]. A new portion of material from the Novaya Zemlya have been located in the collection…”
