Differential diagnosis
Synagelides wuliangensis sp. nov. resembles S. hamatus Zhu, Zhang, Zhang & Chen, 2005 (Zhu et al. 2005: fig. 12a–e) in the shape of the copulatory organs and habitus, but differs in: 1) the second retrolateral tibial apophysis is about two times longer than wide in S. wuliangensis sp. nov. (Fig. 13B), whereas slightly wider than long in S. hamatus (Zhu et al. 2005: fig. 12e); 2) retrolateral tibial apophysis tapers to a tail-shaped terminus in S. wuliangensis sp. nov. (Fig. 13B), whereas it becomes short, spine-shaped and terminates abruptly in S. hamatus (Zhu et al. 2005: fig. 12e); 3) epigynal hood is more than three times longer than wide in S. wuliangensis sp. nov. (Fig. 14A), whereas almost as long as wide in S. hamatus (Zhu et al. 2005: fig. 12b); 4) spermathecae are oval in S. wuliangensis sp. nov. (Fig. 14C), whereas reniform in S. hamatus (Zhu et al. 2005: fig. 12c). Synagelides wuliangensis sp. nov. also somewhat resembles S. logunovi sp. nov. in the general shape of copulatory organs, but can be distinguished by the absence of the retrolateral patellar apophysis and the epigynal hood being more than three times longer than wide in S. wuliangensis sp. nov. (Fig. 174A), whereas the patella retrolateral apophysis is present and the epigynal hood is slightly longer than wide in S. logunovi (Fig. 8A).
Etymology
The species name comes from the type locality; adjective.

Chelicerae (Fig. 14G) yellow, with two promarginal teeth and one retromarginal tooth fissident. Endites, labium, and sternum (Fig. 14E) pale yellow. Legs pale yellow to red-yellow. Spination of leg I (Fig. 14H): femur v2-2-2-2-2; metatarsus v0-2-2. Abdomen (Fig. 14 D–E) elongated; dorsum brown anteriorly and dark posteriorly, with two pairs of muscle depressions and several herringbone stripes; venter gray-white, with dotted lines medially. Palp (Fig. 13 A–F): patella swollen; retrolateral tibial apophysis slender, longer than half the cymbial length, pointed apically; the second retrolateral tibial apophysis paliform, about two times as long as wide; cymbium hairy, with dorsal and prolateral apophyses; bulb inflated; embolus tapered, coiled spirally; median apophysis complicated and sclerotized.

Total length 4.11. Carapace 1.62 long, 1.22 wide. Abdomen 2.35 long, 1.30 wide. Eye sizes and interdistances: AME 0.37, ALE 0.20, PLE 0.19, AREW 1.14, PERW 1.26, EFL 0.93. Legs: I 4.13 (1.21, 2.07, 0.51, 0.34), II 2.72 (0.85, 1.01, 0.54, 0.32), III 2.93 (0.90, 1.01, 0.68, 0.34), IV 3.96 (1.07, 1.51, 1.01, 0.37).

Epigyne (Fig. 14 A–C) longer than wide, with an anterior hood more than three times longer than wide and a pair of posterior arcuated rims; copulatory openings located postero-laterally; copulatory ducts ascending in a S-shape before descending, terminally with short gland ducts which are almost half as long as fertilization ducts; spermathecae oval, touching each other; fertilization ducts extending transversely.
Distribution
