1AFF272C461C5FE5BFB40B82A3CEE955.taxon	distribution	Distribution. Troglophilic species (Mammola et al., 2018). This species is found from the mountainous regions of Europe and the Urals to East Kazakhstan (Esyunin and Efimik 1999). Improphantes improbulus inhabits caves and highlands in Europe (Thaler 1986). In the Urals, it is known to occur in the elphin birch woodland, mountain lichen tundra, limestone denudations and rocks (Esyunin and Efimik 1999). Improphantes improbulus was reported from the Kurmanaevskaya Cave and the Tash-Astinskii Grotto in Urals (Esyunin and Efimik 1999). This species is recorded from the Altai Mountains and from Siberia for the first time.	en	Fomichev, Alexander A.

760C271450B65DAF90F4957397A12EEB.taxon	distribution	Distribution. This is a troglophilic species (Mammola et al. 2018). Metellina merianae is widespread in Europe (Nentwig et al. 2020) and is reported east to Urals (Mikhailov 2013) and the Altai Mountains (Levina and Mikhailov 2004). It was reported from the caves of Iran, the Caucasus, the Crimea, the Russian Plain and the Urals (Marusik et al. 2014; Turbanov et al. 2016). Outside the caves, this species occurs in the shaded habitats with boulders, along the creeks and in the cellars (Marusik et al. 2014). In the northern part of the Altai Mountains it was collected along a swampy stream in a birch forest (Levina and Mikhailov 2004). The species reported from the Novosibirsk Oblast (Barsukovskaya Cave) for the first time. Records in the Barsukovskaya and Gavrilovskaya II Caves represent the northeasternmost localities of its distribution range.	en	Fomichev, Alexander A.

04F6E7BA737352ED857B399A66C0559C.taxon	distribution	Distribution. This species has a Mongolian range (Marusik et al. 2000). It was recorded in the Altai Krai, Altai, Tuva, Khakassia and Buryatia Republics of Russia (Logunov 1997; Marusik et al. 2000; Azarkina and Trilikauskas 2013; Fomichev 2015), south to the Arkhangai Aimag of Mongolia (Marusik and Logunov 1999). This species was reported from the vicinities of the Letuchikh Myshei Cave by Azarkina and Trilikauskas (2013). The species inhabits rocky cliffs and probably is active mostly at night (Marusik et al. 2000). The single female was collected in the entrance part of the cave.	en	Fomichev, Alexander A.
