New data on the spiders (Arachnida: Aranei) from Altai Territory, Russia

Abstract

A list of 65 spider species collected from the Tigirek State Nature Reserve (Altai Territory) is provided. Of them, 22 species are recorded from the reserve for the first time and six species are new to the Altai Mountains. A new species, Parasyrisca volynkini sp.n. (#) is described. Two species are illustrated: the poorly-illustrated female of Leptorhoptrum robustum (Westring, 1851) and Euryopis laeta (Westring, 1861) that is new to the Altai.

New data on the spider fauna (Arachnida, Aranei) of the Altai Territory

“…The spider fauna of the Tigirek State Nature Reserve is complemented by three additional species and now accounts for 180 species in 98 genera and 23 families. Even so, the araneofauna of the reserve seems to consist of more than 240 species (Fomichev, 2016).…”

“…Later, the number of species was increased to 153 thanks to a series of publications by Azarkina & Trilikauskas (2012, 2013aTrilikauskas, 2014). The latest paper by Fomichev [2016] already contains information on 175 spider species recorded from the territory of the Tigirek Reserve. Nevertheless, the spider fauna of the reserve remains poorly inventoried.…”

New data on spiders (Arachnida, Aranei) from the caves of Southwestern Siberia (Russia)

“…This species is distributed from the Tyumen Oblast of Russia, through the Pavlodar Region of Kazakhstan to the Altai Mountains (Tanasevitch et al 2012). It was reported from the subalpine meadows of the Tigirek Mountain Range, which is located 40 km away from Letuchikh Myshei Cave (Fomichev 2016).…”
