Diagnosis.
This species is similar to S. shangrila sp. nov. (Figs 11, 12) in having a hook-shaped retrolateral tibial apophysis and spiraled copulatory openings, but it can be distinguished by the spiral posterior arm of the conductor (vs slightly twisted), the curved copulatory duct (vs columnar), and the bud-shaped spermathecal head (vs round).
Distribution.
China (Beijing, Gansu, Guizhou, Hebei, Hubei, Hunan, Liaoning, Shanxi, Shaanxi, Sichuan, Zhejiang) (Fig. 15).
Remarks.
Although we did not examine the type of S. hedini, the published figures of it (Schenkel 1936; Lehtinen 1967) are clear enough. We carefully compared D. yongshun (type examined, Fig. 10) and S. hedini (Fig. 9), and found that these two species share the same structures, such as the helical posterior arm of conductor, the semicircular embolus originating at about the 9: 00 o’clock position, and two ctenidia located dorso-medially on the tibia. Therefore, we consider D. yongshun to be a junior synonym of S. hedini (Schenkel, 1936).
