Like T. fragilis, this species belongs to the bellottii species group and to the bellottii species subgroup (Chant and McMurtry 2004a).

The biology of that species is totally unknown.

This is the first report of that species from Slovenia.

World distribution: China, Russia, South Korea.

Specimens examined: 2 ♀♀ and 3 ♂♂ in total. Šobec (aasl 418 m, lat. 46°21’22”N, long. 14°9’2”E), 2 ♀♀ and 2 ♂♂ on Picea abies (Pinaceae) and 1 ♂ on Corylus avellana L. ( Betulaceae), 21/VI/2019.

Remarks: The description and measurements of the two adult females and the three adult males (Table 3) collected agree well with those provided by Wainstein and Beglyarov (1971) for Russia, by Wu (1987) for China [for T. magnus, junior synonym of T. volgini according to Ryu and Ehara (1991)] and by Ryu and Ehara (1991) for South Korea. T. volgini is similar to T. herbarius Wainstein but with important differences in setae measurements and less teeth in both digits in chelicerae.
