Type material.
Holotype: China · 1 ♂; Guizhou Province, Tongren City, Yuping Autonomous County, Zhujiachang Town, Yutang Village; 27.30°N, 108.89°E; alt. 546 m; 17 August 2018; D. Li, F.X. Liu, X. Xu, D.Q. Li and L. Yu leg.; XUX-2018-380A. Paratypes: China · 10 ♀♀; same data for the holotype; XUX-2018-373, 374, 375, 376, 377, 378, 379, 380, 382, 382A.
Diagnosis.
Male of S. yuping sp. nov. resembles that of S. pluma and S. xiangnan , but can be distinguished from that of S. pluma by the apical spine of the conductor with a spinule basally (Fig. 5C, D, E View Figure 5 ), the contrategulum with fewer teeth (Fig. 5D View Figure 5 ); from that of S. liui sp. nov. by the conductor with only a long apical spine, and the middle part of conductor covered with numerous small spines (Fig. 5C-E View Figure 5 ); from that of S. xiangnan by the blade-shaped spine of the conductor with one tip (Fig. 5C-E View Figure 5 ), by the semielliptical contrategulum (Fig. 5D, G View Figure 5 ), and by the tegulum with a small terminal apophysis retrolaterally (Fig. 5B, F View Figure 5 ); from that of other Songthela species by the conductor covered with several short spines on the middle part (Fig. 5C-E View Figure 5 ). Females of S. yuping sp. nov. resemble those of S. pluma and S. tianzhu sp. nov., but can be distinguished from those of S. pluma by the arc-shaped anterior margin of the bursa copulatrix (Fig. 5H-K, P-S View Figure 5 ); from those of S. tianzhu sp. nov. by the slightly longer middle genital stalks (Fig. 5H-W View Figure 5 ), and by the rectangular genital area and the slightly deeper depressions (Fig. 5H-K, P-S View Figure 5 ); from those of S. liui sp. nov. by the two pairs of receptacular clusters situated on the dorsal wall of the bursa copulatrix, and the middle genital stalks fused together basally (Fig. 5H-W View Figure 5 ); from those of other Songthela species by four receptacular clusters situated on the dorsal wall of the bursa copulatrix (Fig. 5H-W View Figure 5 ).
Description.
Male (holotype; Fig. 1N View Figure 1 ). Carapace yellow brown, opisthosoma slightly brown, with 12 dark brown tergites, close to each other, 2-6 larger than others, and the 4th largest; sternum narrow, much longer than wide; a few pointed hairs running over ocular area; chelicerae robust with promargin of cheliceral groove with 9 denticles of variable size; legs with sturdy hairs and spines; 7 spinnerets. Measurements: BL 9.65, CL 4.53, CW 3.62, OL 4.63, OW 3.28; ALE> PLE> PME> AME; leg I 15.40 (4.42 + 2.00 + 3.43 + 3.73 + 1.82), leg II 14.06 (4.15 + 1.85 + 3.48 + 2.90 + 1.68), leg III 17.08 (4.26 + 1.88 + 3.38 + 5.25 + 2.31), leg IV 23.05 (5.66 + 2.18 + 4.59 + 7.37 + 3.25).
Palp. Paracymbium with numerous setae and spines at the distal portion (Fig. 5A View Figure 5 ). Contrategulum with an irregular dentate edge and an apophysis proximally (Fig. 5D View Figure 5 ). Tegulum with a serrated marginal apophysis and a dorsal extension of terminal apophysis, and with a small thumb-like terminal tegular apophysis retrolaterally (Fig. 5B, F, G View Figure 5 ). Conductor fused with embolus basally, covered with several small spines in the middle part, and a long blade-shaped apical spine with a spinule basally (Fig. 5C, D, E View Figure 5 ). Embolus with a flat opening in distal portion and numerous ribbed ridges in middle and distal portion (Fig. 5C-G View Figure 5 ).
Female (XUX-2018-382A; Fig. 1M View Figure 1 ). Carapace yellow brown, opisthosoma slightly brown, with 12 dark brown tergites, close to each other, 2-6 larger than others, and the 4th largest; sternum narrow, much longer than wide; a few pointed hairs running over ocular area; chelicerae robust with promargin of cheliceral groove with 12 denticles of variable size; legs with sturdy hairs and spines; 7 spinnerets. Measurements: BL 13.67, CL 6.60, CW 5.43, OL 6.28, OW 5.06; ALE> PLE> PME> AME; palp 11.50 (3.75 + 2.05 + 2.42 + 3.28), leg I 13.37 (4.41 + 2.32 + 2.53 + 2.57 + 1.54), leg II 13.00 (3.85 + 2.30 + 2.27 + 2.79 + 1.79), leg III 13.21 (3.95 + 2.42 + 2.09 + 2.94 + 1.81), leg IV 19.08 (5.35 + 2.64 + 3.35 + 5.38 + 2.36).
Female genitalia. Two pairs of receptacular clusters with tubular stalks, situated on the dorsal wall of the bursa copulatrix. The median ones similar to or slightly larger than the lateral ones, with smooth genital stalks and fused together basally (Fig. 5H-W View Figure 5 ).
Variation.
Females vary in body size. The range of measurements as follows (N = 10): BL 9.65-14.14, CL 4.53-6.60, CW 3.62-5.68, OL 4.59-6.71, OW 3.28-5.30. The number of promargin of cheliceral groove varies from 9-12 (N = 10). Moreover, the female genitalia show somewhat intraspecific variation: the genital stalks of the median receptacular clusters are different in shape, either “Y” shaped (Fig. 5K, Q, R, S View Figure 5 ), “V” (Fig. 5H-J View Figure 5 ), or fused together (Fig. 5P View Figure 5 ); the lateral receptacular clusters are irregular, and larger than the median ones (Fig. 5Q View Figure 5 ).
Etymology.
The species epithet, a noun in apposition, refers to the type locality.
Distribution.
