Type material. Holotype male: CHINA: Hunan Province: Changde City, Hupingshan National Nature Reserve , 30.11°N, 110.78°E, 1395 m, native forest, 16 June 2017, Y. Zhong & Y. Zhu leg. (CBEE). Paratypes: 4 males, 13 females, with same data as holotype ( CBEE) ; 4 males and 4 females ( CBEE) , 1 male and 1 female ( SMF) , Zhangjiajie City , Tianpingshan Scenic Area, 29.79°N, 110.09°E, 1503 m, native forest, 20 June 2017, Y. Zhong & Y. Zhu leg.

Etymology. The specific name is taken from the type locality, Changde City; name in apposition.

Diagnosis. Males of this new species resemble Sinopoda campanacea ( Wang, 1990) ( Wang 1990: figs 1–5) and Sinopoda serrata ( Wang, 1990) ( Wang 1990: figs 17–19; Quan et al. 2013: figs 1–10, 13–15) in having a short embolus and embolus tip, cymbium distinctly longer than tibia, but can be separated by: 1. Palpal tegulum covering proximal part of embolus in S. changde sp. nov. (not so in S. campanacea and S. serrata ); 2. RTA of palp arising medially to proximally from tibia (distally to medially in S. campanacea and S. serrata ). Females of S. changde sp. nov. may be recognised by the following combination of characters: 1. Epigyne with anterio-lateral margins of lateral lobes almost parallel with posterior margin of epigyne; 2. Vulva with glandular appendages extremely short.

Palp as in diagnosis. Embolus arising from tegulum at 8 to 9-o’clock-position. Embolus tip slightly bent, as long as embolic apophysis. Tip of embolic apohysis short and pointed. Spermophor almost straight in ventral view. dRTA digitiform, pointed in ventral view, vRTA broad in retrolateral view ( Figs 13 A–C, 14A–D).

Colouration in ethanol. Prosoma dorsally pale yellowish with two distinct dark lateral bands, these latter distinctly serrated laterally, less so medially. Fovea and radial furrows distinctly marked. Labium and gnathocoxae pale yellowish, the former with distal parts brighter. Sternum pale yellowish, with margin brown. Chelicerae reddishbrown. Legs yellowish-brown with dark spots. Dorsal opisthosoma brown, covered by grey hairs, with three pairs of dark patches laterally. Ventral opisthosoma light brown with irregular pattern ( Figs 14 E–F).

Measurements of palp and legs: Palp 7.2 (2.0, 1.1, 1.7, –, 2.4); I 18.4 (5.2, 1.8, 5.2, 4.6, 1.6); II 19.7 (5.6, 2.1, 5.5, 4.8, 1.7); III 15.9 (5.0, 1.4, 4.3, 3.6, 1.6); IV 17.9 (5.4, 1.3, 4.9, 4.7, 1.6). Leg formula: II-I-IV-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 30 denticles.

Copulatory organ as in diagnosis. Epigynal field wider than long, with short anterior bands. Margins of lobal pockets running parallel to posterior margin of lateral lobes. Glandular appendages short, bent, posterio-laterad. Posterior part of internal duct system distinctly wider than anterior part. Fertilization ducts arising medially on bent posterior part ( Figs 13 D–E, 15A–B).

Colouration in ethanol. As in males, but generally slightly darker, except for ventral OS ( Figs 15 C–D). Distribution. China (Hunan) ( Fig. 62 ).
