The specimens from Hebei and Xinjiang exhibit a slightly curved and shorter row of spines in the posterior phallus compared to material from Europe and Russia (Bolshakov, 2002; Slamka, 2013). In the female genitalia, the accessory signum varies from crescent- or stick-shaped over gradual reduction to complete absence.
