Diagnosis.
Males of Q. sanya sp. nov. can be distinguished from those of Q. baoting sp. nov. by the longer tegulum marginal apophysis with a non-translucent apex (Fig. 4A, D View Figure 4 ), and by the conductor with a bent apex (Fig. 4C, E, F, G View Figure 4 ); from those of the other Qiongthela species by the conductor base with a triangular apophysis ventrally (Fig. 4A-E View Figure 4 ). Females of Q. sanya sp. nov. can be distinguished from Q. australis , Q. yini and Q. yinggezui sp. nov. by the inner receptacular clusters smaller than the lateral ones (Fig. 5A-H View Figure 5 ); from those of the other Qiongthela species by the inner receptacular clusters along the anterior margin of the bursa copulatrix, the laterals located slightly on the dorsal wall of the bursa copulatrix, and by the trapezoidal bursa copulatrix (Fig. 5A-H View Figure 5 ).
Description.
Male (holotype). In alcohol carapace reddish dark; opisthosoma brown, with 12 reddish dark tergites, close to each other, the first 2-7 larger than others, and the fourth largest; sternum narrow, nearly twice as long as wide; a few fine pointed hairs running over the ocular area; chelicerae with promargin of cheliceral groove containing 9 denticles of variable size; legs with firm hairs and spines; 7 spinnerets. Measurements: BL 13.40, CL 6.47, CW 5.87, OL 6.80, OW 5.20; ALE> PLE> PME> AME; leg I 22.06 (6.30 + 1.62 + 5.26 + 5.97 + 2.90), leg II 20.17 (5.16 + 1.50 + 4.81 + 5.77 + 2.94), leg III 22.02 (5.65 + 1.62 + 4.41 + 6.83 + 3.52), leg IV 28.13 (7.15 + 1.87 + 6.00 + 8.93 + 4.17).
Palp. Cymbium with a short projection dorsally (Fig. 4G View Figure 4 ); prolateral side of paracymbium unpigmented and unsclerotised, with numerous setae at the tip (Fig. 4A-C View Figure 4 ). Contrategulum with two distal edges: the inner one strongly dentate, and the outer one smooth, sharp, semi-translucent (Fig. 4A, D, F View Figure 4 ). Tegulum with a long, pointed, distally directed marginal apophysis, the proximally directed terminal apophysis with a dentate margin and continuously narrowing to a rounded, hooked apex (Fig. 4A-E View Figure 4 ). Conductor situated ventro-proximally on embolus, fused with embolus at the basal portion, distal free narrowing to a bent apex (Fig. 4B, C, E-G View Figure 4 ); conductor base with a triangular apophysis ventrally (Fig. 4A-E View Figure 4 ). Embolus largely sclerotised, with a wide, flat sperm duct opening distally, retrolaterally with numerous longitudinal ribs (Fig. 4B, C, E View Figure 4 ).
Female (XUX-2017-215). In alcohol carapace reddish dark; opisthosoma dark brown, with 12 reddish dark tergites, close to each other, the first 2-7 larger than others, and the fourth largest; sternum narrow, much longer than wide; a few fine pointed hairs running over the ocular area; chelicerae with promargin of cheliceral groove containing 10 strong denticles of variable size; legs with firm hairs and spines; 7 spinnerets. Measurements: BL 25.50, CL 11.95, CW 10.97, OL 13.00, OW 10.75; ALE> PLE> PME> AME; palp 18.86 (6.35 + 2.20 + 4.73 + 5.58), leg I 23.55 (8.14 + 3.11 + 5.51 + 4.44 + 2.35), leg II 21.33 (7.25 + 2.68 + 4.87 + 4.25 + 2.28), leg III 22.43 (7.19 + 2.50 + 4.99 + 4.98 + 2.78), leg IV 34.17 (10.27 + 3.17 + 7.11 + 9.07 + 4.55).
Female genitalia. The inner receptacular clusters along the anterior margin of the bursa copulatrix, the lateral ones located slightly on the dorsal wall of the bursa copulatrix; the inner ones smaller than the lateral ones, with short or long genital stalks. The bursa copulatrix trapezoidal (Fig. 5A-H View Figure 5 ).
Variation.
Males and females vary in body size. The range of measurements in males (N = 3): BL 13.40-15.01, CL 6.47-7.21, CW 5.87-6.53, OL 6.16-7.53, OW 4.47-5.20; females (N = 25): BL 15.41-27.74, CL 7.32-14.14, CW 6.23-11.59, OL 7.33-13.49, OW 5.70-11.84. In addition, female genitalia show intraspecific variation: the inner pair of the receptacular clusters along the anterior margin of the bursa copulatrix upward, with short or long genital stalks (Fig. 5A-E, G View Figure 5 ), or clusters toward the dorsal margin (Fig. 5F, H View Figure 5 ).
