Sinopoda liui Zhong et al., 2017: 160 , figs 5C–D, 6C–D, 15C–D (♀, holotype, China: Fujian Province, Longxishan National Nature Reserve, 26.40°N, 117.22°E, 985 m, native forest, 18 July 2013, Y. Zhong & X.W. Cao, deposited in CBEE, examined; 10 ♀, paratypes, same date, in CBEE, examined).

Additional material examined. 4 males and 6 females ( CBEE) , 1 male and 1 female ( SMF), same locality as holotype, 28 July 2018, Y. Zhong leg.

Diagnosis. Males of this species resemble those of S. tengchongensis Fu & Zhu, 2008 ( Fu & Zhu 2008: figs 2–5) in having the embolus tip distinctly shorter than the embolic apophysis and the spermophor distinctly curved in ventral view, but are distinguished from the latter by the following characters: 1. Inner margin of dRTA distinctly curved in ventral view (almost straight in S. tengchongensis ); 2. RTA extending moderately to the retrolateral side (extending and bulging strongly to the retrolateral side in S. tengchongensis ); 3. Tegulum covering proximal part of embolus (not in S. tengchongensis ); 4. Embolus distally leaf-shaped in ventral view (slender in S. tengchongensis ). Females of S. liui are similar to those of S. aequalis sp. nov. ( Figs 4 D–E, 6A–B) in having sutured lateral lobes with two slight humps posteriorly and a moderately wide lobal septum anteriorly, but can be separated by: vulva with glandular appendages wider than posterior parts of spermathecae, with distal ends slightly curved (as wide as, not curved in S. aequalis ).

Description. Male: Measurements: PL 5.8, PW 5.2; AW 2.6; OL 6.0, OW 3.3. Eyes: AME 0.22, ALE 0.34, PME 0.24, PLE 0.41, AME–AME 0.21, AME–ALE 0.10, PME–PME 0.32, PME–PLE 0.56, AME–PME 0.40, ALE–PLE 0.43, CH AME 0.15, CH ALE 0.21. Spination: Palp: 131, 101, 1021; Fe: I–III 323, IV 331; Pa: I–IV 101; Ti: I–IV 2326; Mt: I–II 2024, III–IV 3036. Measurements of palp and legs: Palp 10.2 (3.7, 1.6, 1.6, –, 3.3); I 27.0 (7.0, 2.4, 7.5, 7.7, 2.4); II 30.2 (8.3, 2.5, 8.3, 8.4, 2.7); III 21.3 (6.0, 2.1, 5.7, 5.7, 1.8); IV 23.9 (6.6, 2.0, 6.4, 6.9, 2.0). Leg formula: II-I-IV-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 21 denticles.

Palp as in diagnosis. Cymbium distinctly longer than tibia. Embolus arising from tegulum at 7:30 to 8-o’clockposition, with embolic tip distinctly shorter than embolic apophysis. Tegulum partly covering proximal part of embolus. RTA originating medially to proximally from tibia ( Figs 31 A–C, 32A–D).

Colouration in ethanol. Dorsal prosoma yellowish-brown, with two dark lateral bands with serrated inner and outer margin, lateral margins dark, with yellow submarginal transversal light band posteriorly. Labium and gnathocoxae yellowish-brown, both with distal parts brighter. Sternum yellowish-brown, with margin brown. Chelicerae deep reddish-brown. Legs yellowish-brown with dark spots. Dorsal opisthosoma reddish-brown, covered by gray hairs, lateral field of opisthosoma with three pairs of black patches. Ventral opisthosoma brown with irregular pattern ( Figs 32 E–F).

Redescription: Female: epigynal field wider than long, with short anterior bands and one slit sensillum on each side close to the epigynal field. Glandular appendages with swollen ends. Posterior parts of spermathecae small, fertilization ducts arising posterio-laterally ( Figs 33 A–B). Further details and measurements see Zhong et al. (2017).

Distribution. China (Fujian) ( Fig. 62 ).
