Type material.
Holotype: China·1 ♂; Hunan Province, Hengyang City, Mt. Heng, Xiangnan Temple; 27.28°N, 112.69°E; alt. 959 m; 18 Aug. 2011; F.X. Liu, X. Xu, R. Xiao leg.; XUX-2011-063.
Paratypes: China·2 ♀♀; same data as for holotype; XUX-2011-070, 071.
Diagnosis.
Male of S. xiangnan sp. nov. resembles that of S. pluma , but can be distinguished from the latter by the conductor with two apical spines, the longer spine with a bifid apex (Fig. 5A, B, D, E, G View Figure 5 ), by the contrategulum with only one dentate margin and with a small apophysis located proximally (Fig. 5A, B, D, E View Figure 5 ), and by the tegulum with a finger-like terminal apophysis in retrolateral view (Fig. 5C, F View Figure 5 ); from that of other Songthela species by the central part of the conductor with several short spines, the blade-shaped conductor spine with a bifid apex (Fig. 5A, B, D, E, G View Figure 5 ). Females of S. xiangnan sp. nov. differ from those of S. pluma by the longer genital stalks of the median receptacular clusters (Fig. 5H View Figure 5 ), and the smaller lateral receptacular clusters with obscure genital stalks (Fig. 5H View Figure 5 ); from those of other Songthela species by the median receptacular clusters with longer and trachea-shaped genital stalks, obviously larger than the lateral ones, the lateral receptacular clusters with obscure genital stalks, situated slightly dorsolaterally (Fig. 5H View Figure 5 ).
Description.
Male (holotype; Fig. 4E View Figure 4 ). Carapace yellow with several short hairs on the margin; opisthosoma light brown; tergites yellowish-brown; sternum narrow; few fine pointed hairs running over ocular area; chelicerae robust with promargin of cheliceral groove with 12 denticles; legs with sturdy hairs and spines; opisthosoma with 12 tergites, the second to fifth tergite larger than remaining ones and third the largest; six spinnerets.

Palp. Prolateral side of paracymbium unpigmented and unsclerotized, with numerous setae and spines on the tip (Fig. 5A View Figure 5 ); contrategulum with serrate margin and with a small apophysis located proximally (Fig. 5A, B, D, E View Figure 5 ); tegulum with a dentate marginal apophysis and the dorsal extension of terminal apophysis, and a long finger-like terminal apophysis in retrolateral view (Fig. 5C, F View Figure 5 ); conductor base wide and fused with embolus, unsmooth middle portion covered with several short spines, a long blade-shaped spine with a bifid apex and a short spine basally (Fig. 5A, B, D, E View Figure 5 ); embolus with a flat opening in distal portion and ridged apophysis in middle ventral portion (Fig. 5A-G View Figure 5 ).
Female (XUX-2011-070; Fig. 4D View Figure 4 ). Carapace yellow brown with several hairs on the margin; opisthosoma brown; fourth to sixth tergite light brown with some brown flecks, remaining tergites dark brown; sternum narrow; few fine pointed hairs running over ocular area; chelicerae robust with promargin of cheliceral groove with 12 denticles; legs with sturdy hairs and spines; opisthosoma with 12 tergites, the second to fifth tergite larger than remaining ones and fourth the largest; six spinnerets. Measurements: BL 14.31, CL 6.44, CW 5.94, OL 7.04, OW 6.18; ALE> PLE> PME> AME; palp 12.59 (4.35 + 2.31 + 2.64 + 3.29), leg I 14.28 (4.64 + 2.52 + 2.78 + 2.80 + 1.54), leg II 13.76 (4.25 + 2.42 + 2.52 + 3.00 + 1.57), leg III 14.32 (4.08 + 2.44 + 2.53 + 3.41 + 1.86), leg IV 20.37 (5.72 + 2.94 + 3.74 + 5.30 + 2.67).
Female genitalia. The median pair of the receptacular clusters along the anterior margin of the bursa copulatrix, with long, trachea-shaped and slightly ventral-tilted genital stalks close to each other basally but separated from each other distally; the middle receptacular clusters obviously larger than the lateral ones; the lateral receptacular clusters with obscure genital stalks, situated slightly dorsolaterally (Fig. 5H, I View Figure 5 ); the anterior margin of the bursa copulatrix trapezoid (Fig. 5H, I View Figure 5 ).
