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 View 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 View Figure 5 (a–d)), (2) relatively wider base of septum and (3) larger head of receptacle (see Figure 5 View Figure 5 (a–d)).
