Holotype ♂ (ZMMU), TAJIKISTAN: Khatlon Region: Dangara Dist., Sanglok Mt. range, above Shar-Shar Pass, 38.298950, 69.226633, 1700–2060 m, 29 April 2015 (Yu.M. Marusik). Paratypes: 5♂ 9♀ (ZMMU), same data as the holotype; 4♂ 2♀ (ZMMU), Dangara dist., Sanglok Mt. range, above Shar-Shar Pass, 38.218183, 69.238033, 1362 m, 30 April 2015 (Yu. M.

Etymology
The specific epithet refers to the type locality.
Diagnosis
The male of this species differs from that of S. denisi by (1) the tip of RTA bent at a different angle (see Figure 4 (a,c)), (2) smaller and claw-like process of tegular apophysis (Tp) located anteriorly (vs larger, spine-like, and located prolaterally), and (3) having small ridges on the anterior edge of tegular apophysis (vs having teeth instead of ridges). The female of the new species differs from that of the type species by (1) the converging lateral margins of fovea (vs subparallel; see Figure 5 (a–d)), (2) relatively wider base of septum and (3) larger head of receptacle (see Figure 5 (a–d)).
