Etymology. The specific name comes from the Chinese word “ wa ”, the name of one of the Chinese ethnic minorities that mainly live in Yunnan province of China; noun in apposition.
Diagnosis. The new species resembles S. acicularis Wang, Griswold & Ubick, 2009 ( Zhu et al., 2017: 135, figs 48) in having the similar filiform embolus, retrolateral tibial apophysis and median apophysis of male palp ( Figs 6C–E View FIGURE 6 ; Zhu et al., 2017: figs 48C–D), position and shape of epigynal tooth of female epigyne ( Fig. 6F View FIGURE 6 ). But can be distinguished by conductor short and hook-like ( Figs 6C–D View FIGURE 6 ) vs. long and sickle-like in S. acicularis ( Zhu et al., 2017: figs C–D); condutor dorsal apophysis boot-shaped in ventral view ( Fig. 6D View FIGURE 6 ) vs. Triangular in S. acicularis ( Zhu et al., 2017: fig. 48C); patellar apophysis triangular in retrolateral view ( Fig. 6E View FIGURE 6 ) vs. boot-shaped in S. acicularis ( Zhu et al., 2017: fig. 48D). Female can be distinguished by approximate rectangular with chear margin atrium ( Fig. 6F View FIGURE 6 ) vs. with wavy anterior margin and indistinct posterior margin in S. acicularis ( Zhu et al., 2017: fig. 48A); copulatory ducts tightly attached, and even have a small overlap ( Fig. 6G View FIGURE 6 ) vs. significant separation ( Zhu et al., 2017: fig. 48B).
Description. Male holotype ( Fig. 6A View FIGURE 6 ) total length 9.73. Prosoma 5.27 long, 3.28 wide; opisthosoma 4.56 long, 2.96 wide. Eye sizes and interdistances: AME 0.21, ALE 0.26, PME 0.20, PLE 0.24; AME–AME 0.13, AME–ALE 0.08, PME–PME 0.16, PME–PLE 0.24, ALE–PLE 0.07. MOA 0.64 long, anterior width 0.48, posterior width 0.56. Clypeus height 0.26. Chelicerae with three promarginal and five retromarginal teeth. Leg measurements: I 14.72 (4.46, 5.64, 2.82, 1.80); II 15.00 (4.02, 4.85, 3.85, 2.28); III 13.83 (3.68, 4.27, 3.68, 2.20); IV 18.15 (4.65, 5.67, 5.21, 2.62). Leg formula: 4213.
Palp ( Figs 6C–E View FIGURE 6 ). Patellar apophysis length approximately 2/3 of patellar and triangular in retrolateral view. Retrolateral tibial apophysis slightly longer than half of the tibia. Lateral tibial apophysis wide and significantly separated from retrolateral tibial apophysis. Cymbial furrow short, about 1/3 length of cymbium; Conductor curved and with pointed tip. Condutor dorsal apophysis boot-shaped and shorter than conductor in ventral view. Median apophysis spoon-like, round and broad. Embolus short, filamentous, originating from inner base.
Female paratype (SWUC-T-AG-122-02, Fig. 6B View FIGURE 6 ) total length 11.99. Prosoma 6.02 long, 3.83 wide; opisthosoma 6.19 long, 3.91 wide. Eye sizes and interdistances: AME 0.22, ALE 0.26, PME 0.23, PLE 0.26; AME–AME 0.16, AME–ALE 0.08, PME–PME 0.20, PME–PLE 0.29, ALE–PLE 0.12. MOA 0.75 long, front width 0.57, back width 0.67. Clypeus height 0.27. Chelicerae with three promarginal and five retromarginal teeth. Leg measurements: I 15.35 (4.25, 5.20, 3.75, 2.15); II 13.66 (3.96, 4.59, 3.15, 1.96); III 12.58 (3.48, 3.80, 3.49, 1.81); IV 16.50 (4.41, 5.33, 4.39, 2.37). Leg formula: 4123.
Epigyne ( Figs 6F–G View FIGURE 6 ). Epigynal plate longer than wide. Epigynal teeth short, but longer than twice as long as wide. Atrium approximate rectangular with clear margin. Copulatory ducts broad, tightly attached, and even have a small overlap. Spermathecae short, convoluted, and separated by a small distance equal to their 1/5 length. Spermathecal heads round, originating from middle of anterior spermathecae. Fertilization ducts hook-shaped.
Variation. Females ( n = 2) total length 11.99–13.98.
Distribution. Known only from the type locality, Yunnan, China ( Fig. 7 View FIGURE 7 ).
