Sinopoda longiducta Zhang et al., 2015: 69 , figs 38–41, 46–48 ad part. (3♀, paratypes, China: Sichuan Province, Fengtongzhai Natural Reserve, 30º25’N, 102º50’E, 970 m, evergreen broad-leaf forest, 29 June 2012, M.X. Liu, 1 female in MHBU, SP- SC-12-0602, 2 females in SWUC SP-SC-12-0603-0610, examined; female = mismatched).

Type material. Holotype male: CHINA: Sichuan Province : Yaan City, Yingjing County, Longcanggou National Nature Reserve , 29.61°N, 102.90°E, 1581 m, on the rock, 4 May 2016, Y. Zhong, Y. Zhu & H. Zhang leg. (CBEE). Paratypes: 20 males and 40 females ( CBEE) , 1 male and 1 female ( SMF) , with same data as holotype ; 3 males, Yaan City , Yingjing County, Yunfengshan Scenic Area, 29.77°N, 102.88°E, 1583 m, near road, 2 May 2016, Y. Zhong, Y. Zhu & H. Zhang leg. ( CBEE) ; 5 females, Yaan City , Baoxing County, Fengtongzhai National Nature Reserve, 30.57°N, 102.88°E, 1063 m, native forest, 5 May 2016, Y. Zhong, Y. Zhu & H. Zhang leg. ( CBEE) .

Additional material examined. CHINA: Yunnan Province : 6 females, Zhaotong City, Daguan County, Huanglianhe Scenic Area , 27.73°N, 103.92°E, 1558 m, native forest, 4 July 2016, Yang Zhong, Yang Zhu & He Zhang leg. (CBEE).

Etymology. The specific name is taken from the type locality, Yaan City; adjective.

Remarks. We examined a large sample (23 males and 41 females) from the same rock in Longcanggou National Nature Reserve of Sichuan Province. The females are identical to the paratype females of S. longiducta as described by Zhang et al. (2015) and are therefore transferred to S. yaanensis sp. nov.

Diagnosis. This new species resembles S. ovalis sp. nov. ( Figs 43 A–E, 44A–D, 45A–B) in having the distal embolus hook-shaped, vRTA stout, serrated with a pointed tip from ventral view and spermathecae bulging laterally. The male differs from S. ovalis by: Embolic tip as long as embolic apophysis (distinctly shorter in S. ovalis ) ( Figs 43 A–C, 44A–D). The female is differentiated from S. ovalis by the swollen ends of the glandular appendages (slightly narrower in S. ovalis ).

Description. Male (holotype): Measurements: PL 6.5, PW 5.9; AW 2.9; OL 7.4, OW 4.5. Eyes: AME 0.28, ALE 0.39, PME 0.36, PLE 0.39, AME–AME 0.30, AME–ALE 0.14, PME–PME 0.42, PME–PLE 0.67, AME–PME 0.47, ALE–PLE 0.52, CH AME 0.24, CH ALE 0.31. Spination: Palp: 131, 101, 1021; Fe: I–III 323, IV 331; Pa: I–IV 101; Ti: I 2026, II–IV 2326; Mt: I–II 1014, III 2026, IV 3136. Measurements of palp and legs: Palp 12.9 (4.4, 1.9, 2.7, –, 3.9); I 39.6 (10.2, 3.4, 11.9, 12.6, 3.6); II 42.8 (11.3, 3.4, 11.9, 12.6, 3.6); III 33.0 (9.1, 3.0, 9.1, 8.9, 2.9); IV 37.0 (10.1, 3.0, 9.8, 10.5, 3.6). Leg formula: II-I-IV-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 28 denticles.

Palp as in diagnosis. Cymbium distinctly longer than tibia. Embolus arising from tegulum at 6 to 7-o’clock-position in ventral view. Embolic apophysis curved perpendicularly in verntral view, with leaf-shaped end. Tegulum covering parts of proximal embolus. Spermophor curved in ventral view. RTA relatively small, arising distally to medially from tibia. Both dRTA and vRTA with blunt ends, dRTA slightly longer than vRTA ( Figs 56 A–C, 57A–D).

Colouration in ethanol. Dorsal prosoma yellowish-brown, with yellow posterior submarginal transversal light band continuing anteriorly as narrow light submarginal bands along lateral sides between dark margins and broad dark longitudinal bands. Labium and gnathocoxae yellowish-brown, both with distal parts lighter. Sternum yellowish-brown. Chelicerae deep reddish-brown. Legs yellowish-brown with dark spots. Dorsal opisthosoma dark brown, covered by grey hairs with light longitudinal heart patch. Ventral opisthosoma yellowish-brown to reddish-brown, with irregular pattern ( Figs 57 E–F).

Redescription. Female: lateral lobes fused, with eight fusion bubbles along median line. Internal ducts running parallel along the median line, diverging strongly posteriorly ( Figs 58 A–B). Further details and measurements see Zhang et al. (2015).

Distribution. China (Sichuan; Yunnan) ( Fig. 62 ).
