Sinopoda longiducta Zhang et al., 2015: 69 , figs 33–37, 42–45 (Ƌ, holotype, China: Sichuan Province, Fengtongzhai Natural Reserve, 30º25’N, 102º50’E, 970 m, evergreen broad-leaf forest, 29 June 2012, M.X. Liu, deposited in MHBU, SP-SC- 12-0601, not examined; 6Ƌ, paratypes, same data, in SWUC SP-SC-12-0603-0610, examined; not female = S. yaanensis sp. nov.).

Remarks. A series of field collections in Sichuan and Yunnan provinces were carried out by the colleagues of Hubei University in 2016. 19 male and 17 female specimens were collected in these field exploratories, among which several pairs were captured during mating. Later, the males were identified as S. longiducta in the lab, but the females were not the same as the ones described by Zhang et al. 2015. Here, we provide the true female of S. longiducta and transfer the presumed female of S. longiducta to S. yaanensis sp. nov. in this paper.

Material examined. CHINA: Sichuan Province: 11 males and 6 females (CBEE), 1 male and 2 females ( SMF) , Yaan City, Baoxing County, Fengtongzhai National Nature Reserve , 30.57°N, 102.88°E, 1063 m, native forest, 5 May 2016, Y. Zhong, H. Zhang & Y. Zhu leg. ( CBEE) ; 7 males, 4 females, Yaan City, Yingjing County, Longcanggou National Nature Reserve , 29.61°N, 102.90°E, 1581 m, native forest, 4 May 2016, Y. Zhong, H. Zhang & Y. Zhu leg. ( CBEE) . Yunnan Province: 6 females, Zhaotong City, Daguan County, Huanglianhe Scenic Area , 27.72°N, 103.92°E, 1558 m, native forest, 4 July 2016, Y. Zhong, Y. Zhu & H. Zhang leg. ( CBEE) .

Diagnosis. Males of this species resemble those of S. globosa Zhang, Zhang & Zhang, 2015 ( Zhang et al. 2015: figs 19–21, 26–29) and S. triangula Liu, Li & Jäger, 2008 ( Liu et al. 2008: figs 7A–C) in having the triangular projection at the subdistal embolus and dRTA slender, with tip finger-shaped in ventral view, but differ from S. globosa and S. triangula by: spermophor almost straight, both embolic tip and distal embolic apophysis more slender (35A–D). Females of this species are similar to those of S. dehiscens ( Figs 20 A–B, 21A–B) and S. erromena ( Figs 22 A–B, 23A–B) in having massive lateral lobes and a moderately wide lobal septum anteriorly, but it can be distinguished from those species by the long and slender internal duct system (shorter and stouter in S. dehiscens and S. erromena ) ( Figs 34 A–B, 36A–B).

Redescription. Male: embolus arising from tegulum at 7 to 8-o’clock-position in ventral view. Tegulum covering proximal part of embolus. RTA arising distally from tibia with distinct brush of stiff hairs (35A–D). Further details and measurements see Zhang et al. (2015).

Female: Measurements: PL 5.8, PW 5.3;AW 3.0; OL 7.1, OW 4.3. Eyes:AME 0.21, ALE 0.35, PME 0.25, PLE 0.35, AME–AME 0.23, AME–ALE 0.12, PME–PME 0.36, PME–PLE 0.49, AME–PME 0.45, ALE–PLE 0.49, CH AME 0.22, CH ALE 0.30. Spination: Palp: 141, 101, 2121, 2112; Fe: I–III 323, IV 331; Pa: I–IV 000; Ti: I–II 2026, III–IV 2226; Mt: I–II 1014, III–IV 3036. Measurements of palp and legs: Palp 7.5 (2.4, 1.1, 1.7, –, 2.3); I 20.5 (6.2, 2.3, 5.8, 4.7, 1.5); II 22.7 (6.9, 2.6, 6.4, 5.1, 1.7); III 19.0 (5.9, 2.1, 5.2, 4.3, 1.5); IV 21.4 (6.4, 2.1, 5.5, 5.6, 1.8). Leg formula: II-IV-I-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 38 denticles.

Copulatory organ as in diagnosis. Epigynal field wider than long, with long anterior bands and one slit sensillum on the left side separated from epigynal field by two of its diametres. Lateral lobes fused with ca. 15 fusion bubbles along median line in posterior half. Glandular appendages distinctly narrower than posterior parts of spermathecae. Fertilization ducts arising posterioly ( Figs 34 A–B, 36A–B).

Colouration in ethanol. Dorsal prosoma yellowish-brown, covered almost entirely by black hairs, except for a yellow X-shaped patch along fovea and some small spots laterally, with yellow submarginal transversal light band posteriorly. Fovea and radial furrows distinctly marked. Labium and gnathocoxae yellowish-brown, both with distal parts lighter. Sternum yellowish-brown. Chelicerae deep reddish-brown. Legs light brown with dark spots. Dorsal opisthosoma brown, covered by grey setae, posterior half of opisthosoma with three pairs of black patches. Ventral opisthosoma greyish-brown covered by short dark-grey setae, darker in front of spinnerets, laterally with irregular patches ( Figs 36 C–D).

Distribution. China (Sichuan; Yunnan, new province record) ( Fig. 62 ).
