Diagnosis and description.

See Efimik (1999), Chen et al. (2003), Yin et al. (2012), and Jang et al. (2023). Habitus as in Figs 21 A – C , 22 A – C . Male palp as in Fig. 21 D – F , epigyne as in Fig. 22 D, E .

Distribution.

Russia (Southern Sakhalin), China (Guizhou, Hubei; Fig. 23 ), Korea, Japan.

Comments.

The species was reported as a new record for China by Chen et al. (2003) based on materials from Xishui National Nature Reserve in Guizhou. Subsequent literature has reported the distribution of this species in Henan and Hunan provinces ( Zhu and Zhang 2011; Yin et al. 2012). Newly available specimens indicate that the species is also distributed in Guiyang City and Fanjingshan National Nature Reserve in Guizhou Province (Fig. 23 A ), as well as Jiugongshan National Nature Reserve in Hubei Province (Fig. 23 B ). This paper provides the first formal report of the species’ distribution in Hubei Province.
