Type material.
Holotype: CHINA· 1 ♂; Hainan Province, Qiongzhong County, 3.7 Km to Yinggezui; 19.07°N, 109.55°E; alt. 710 m; 11 August 2017; D. Li, F.X. Liu, Z.T. Zhang and X. Xu leg.; XUX-2017-114 (matured on 29 September 2017 at HNU). Paratypes: CHINA · 3 ♀♀; same data as for holotype; XUX-2017-115, 116, 121.
Diagnosis.
Male of Q. yinggezui sp. nov. differs from that of Q. australis by the conductor base wide and with a bent apex (Fig. 6A-F View Figure 6 ), and by the shorter paracymbium (Fig. 6A View Figure 6 ); from Q. nui by the embolus with a smooth surface retrolaterally (Fig. 6B, C, E View Figure 6 ); from Q. baoting sp. nov. by the cymbium with an elongated projection (Fig. 6F View Figure 6 ), and by the conductor with a bent apex (Fig. 6B-E View Figure 6 ); from Q. jianfeng , Q. qiongzhong sp. nov. and Q. sanya sp. nov. by the scutiform marginal apophysis of the tegulum thick basally and pointed distally (Fig. 6A-F View Figure 6 ), and by the embolus with a smooth surface retrolaterally (Fig. 6B, C, E View Figure 6 ). Females of Q. yinggezui sp. nov. can be distinguished from those of Q. australis by the similar-sized receptacular clusters, and the lateral ones slightly located on the dorsal wall of the bursa copulatrix (Fig. 6G View Figure 6 ); from Q. yini by the receptacular clusters with more granula (Fig. 6G, H View Figure 6 ); from Q. sanya sp. nov. by the lack of genital stalks (Fig. 6G, H View Figure 6 ); from those of the other Qiongthela species by the inner receptacular clusters situated at the anterior margin of bursa copulatrix, the lateral pair located on the dorsal wall of the bursa copulatrix (Fig. 6G, H View Figure 6 ).
Description.
Male (holotype). In alcohol carapace light reddish brown; opisthosoma light brown, with 12 brown tergites, separated from 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 13.60, CL 5.99, CW 6.30, OL 7.29, OW 5.48; ALE> PLE> PME> AME; leg I 17.44 (4.82 + 1.55 + 4.10 + 4.51 + 2.46), leg II 17.50 (4.73 + 1.43 + 3.97 + 4.80 + 2.57), leg III 16.73 (4.68 + 1.36 + 2.40 + 5.59 + 2.70), leg IV 25.19 (6.52 + 1.62 + 5.28 + 8.00 + 3.77).
Palp. Cymbium with an elongated projection dorsally (Fig. 6F View Figure 6 ); prolateral side of paracymbium unpigmented and unsclerotised, with numerous setae at the tip (Fig. 6A, B View Figure 6 ). Contrategulum with a proximally irregular dentate edge and two distal edges: the inner one dentate, the outer one smooth, sharp, semi-translucent, fused with the inner one at the middle portion of contrategulum (Fig. 6A, D-F View Figure 6 ). The marginal apophysis of tegulum long, pointed with a sharp apex, a proximally directed terminal apophysis with finely dentate margin and continuously narrowing to a rounded, hooked apex (Fig. 6A-E View Figure 6 ). Conductor situated ventro-proximally on embolus, fused with embolus at the basal portion, distal free narrowing to a bent apex (Fig. 6A-C, E View Figure 6 ). Embolus largely sclerotised, with a wide, flat sperm duct opening, and with a smooth surface retrolaterally (Fig. 6A-E View Figure 6 ).
Female (XUX-2017-121). In alcohol carapace reddish brown; opisthosoma brown; opisthosoma with 12 tergites, closed to each other, the first 2-7 larger than others, and the fourth largest; sternum narrow, more than twice the width; a few fine pointed hairs running over the ocular area; chelicerae with promargin of cheliceral groove containing 10 denticles of variable size; legs with firm hairs and spines; 7 spinnerets. Measurements: BL 14.76, CL 7.03, CW 6.39, OL 7.82, OW 6.03; ALE> PLE> PME> AME; palp 13.30 (5.30 + 1.23 + 2.85 + 3.91), leg I 14.35 (4.84 + 1.54 + 3.21 + 2.95 + 1.82), leg II 12.72 (3.54 + 1.24 + 2.97 + 2.99 + 1.98), leg III 13.78 (4.20 + 1.28 + 2.60 + 3.71 + 1.99), leg IV 20.21 (5.29 + 1.38 + 4.52 + 5.78 + 3.24).
Female genitalia. Two paired of the similar-sized receptacular clusters, the inner ones along the anterior margin of the bursa copulatrix, and the lateral ones located slightly on the dorsal wall of the bursa copulatrix, without genital stalks (Fig. 6G, H View Figure 6 ).
