Etymology.
The specific name, derived from the type locality, is a noun in apposition.
Diagnosis.
The male of this new species can be distinguished from S. sanxiandian sp. nov. by the shield retrolateral tibial apophysis (RTA) (vs. ear-shaped), the anterior part of the tegulum lacking lateral apophysis (vs. present in S. sanxiandian sp. nov.) and the relatively blunt embolic apophysis (EA) in retrolateral view (vs. sharp in S. sanxiandian sp. nov.) (cf. Fig. 7 View Figure 7 vs. Fig. 2 View Figure 2 ).
Description.
Male. Habitus as in Fig. 6A, B View Figure 6 . Total length 10.45. Carapace: 5.6 long, 4.21 wide. Carapace covered with abundant short hairs. Eye sizes and interdistances (Fig. 6C View Figure 6 ): AME 0.35, ALE 0.24, PME 0.3, PLE 0.29, AME-AME 0.2, AME-ALE 0.08, PME-PME 0.27, PME-PLE 0.23, AME-PME 0.2, AME-PLE 0.41, ALE-ALE 0.96, PLE-PLE 1.43, ALE-PLE 0.07. MOA 0.76 long, front width 0.8, back width 0.85. Chelicera (Fig. 6D View Figure 6 ) with three promarginal and six retromarginal teeth. Abdomen: 4.79 long, 3.14 wide. Leg measurements: I 15.93 (4.62, 1.44, 4.18, 3.64, 2.05); II 15.78 (4.41, 1.9, 3.75, 3.73, 1.99); III 13.51 (3.75, 1.58, 3.15, 3.29, 1.74); IV 18.24 (4.84, 1.83, 4.29, 5.37, 1.91); spination (Fig. 6E, F View Figure 6 ): I Fe: d3, p1; Ti: v7; Mt: v4; II Fe: d1, p1; Ti: r3, v7; Mt: r2, v4; III Fe: d3, r1; Ti: p4, r2, v4; Mt: p4, r1, v5; IV: Fe: d3, r1; Ti: p3, r2, v2; Mt: p2, r2, v2.
Colouration (Fig. 6 View Figure 6 ). Carapace and chelicerae dark brown. Endites and labium red-brown to dark brown. Sternum dark brown. Legs: femora I-IV dark brown, tibia and metatarus IV red to dark brown; patellae I-IV, tibiae and metatarsi I-III and tarsi I-IV red. Abdomen dark brown, medially with a pale serrulate marking. Spinnerets yellow-brown.
Palp as in Fig. 7 View Figure 7 . Tibia with distinct retrolateral groove, ventral apophysis (VTA) thumb-like in ventral view. Retrolateral tibial apophysis (RTA) shield in retrolateral view, nearly as long as tibial length, ventral surface with four lines of short cone-shaped spines (CS). Prolateral tibial apophysis (PTA) thick horn-like, strongly sclerotised, nearly as long as 1/3 of tibia. Tegulum with strongly sclerotized apex. Subtegulum (St) with many wrinkles on posterolateral tegulum. Sperm duct (SD) S-shaped in posterior part. Embolus (E) spine-like, with thick base, forming a C-shape with short blunt embolic apophysis (EA), nearly 4 × longer than embolic apophysis.
