Remarks. Originally described from Primorskiy kray, Russian Far East (Mikhaljova & Golovatch, 1981), this species appears to be quite widespread and common there. It has also been recorded in different territories of North Korea (Mikhaljova et al., 2000). This is a litter-dwelling species, also registered in caves (Mikhaljova, 1993, 1997). The species displays dimorphism, i.e. two distinct male morphs (digitata and simplificata) and a continuous variation range in females, all coexisting.

Distribution. Russia: Far East (Primorskiy kray), North Korea.
