Etymology.

The specific name is a patronym after Prof. Xiaoqi Mi (Tongren, China), who help us greatly with this taxonomic study; noun (name) in genitive case.

Diagnosis.

The male of Synagelides mii sp. nov. resembles that of S. tangi Liu, Chen, Xiao, Xu & Peng, 2017 in having a similar RTA, but it can be easily distinguished by the presence of a DTA and by the blunt PCA (Fig. 17A, B ), whereas a DTA is absent and the PCA is pointed in S. tangi ( Liu et al. 2017: figs 5G, 6D). The female of this new species resembles that of S. leigongensis Wang, Mi, Irfan & Peng, 2020 in having very large, transversely extending spermathecae, but it can be easily distinguished by the following: (1) the presence of an epigynal hood (Fig. 18A, B ), which is absent in S. leigongensis ( Wang et al. 2020: fig. 6A); (2) the spermathecae extend anterolaterally (Fig. 18B, C ), whereas they extend posterolaterally in S. leigongensis ( Wang et al. 2020: fig. 6C).

Description.

Male (Figs 17 , 18D, E, G, H ). Total length 3.31. Carapace 1.54 long 1.08 wide. Abdomen 1.83 long, 0.88 wide. Clypeus 0.02 high. Eye sizes and inter-distances: AME 0.38, ALE 0.22, PLE 0.20, AERW 1.08, PERW 1.08, EFL 0.92. Legs: I 4.07 (1.25, 1.10, 1.01, 0.43, 0.28), II 2.51 (0.70, 0.38, 0.60, 0.50, 0.33), III 2.64 (0.73, 0.38, 0.60, 0.60, 0.33), IV 3.39 (0.90, 0.43, 0.88, 0.83, 0.35). Carapace stippled, dark yellow to red-yellow, covered with pale, thin setae and white scale setae, with pair of longitudinal, dark patches mediolaterally on eye field; fovea oval. Chelicerae yellow, with two promarginal teeth and one retromarginal tooth. Endites colored as chelicerae, with pale inner margins. Labium dark brown, almost linguiform. Sternum almost shield-shaped. Legs pale to yellow except femora I and IV brown to red-brown, with three and two spines on tibiae I and metatarsi I, respectively. Abdomen elongated, dorsum red-brown, with transverse, white stripe of setae medially and several transverse dotted lines posteriorly; venter brown. Palp (Fig. 17A-E ): femur longer than wide, with triangular, prolateral apophysis; patella enlarged, longer than wide; tibia wider than long, with disciform VTA in retrolateral view, flat RTA curved anteroventrally, and blunt apically, and sclerotized, triangular DTA; cymbium longer than wide; bulb swollen, with sperm ducts extending along margin; embolus tapered, twisted; MA elongated, with spine-shaped processes on retrolateral portion of distal half and anterior margin.

Female (Fig. 18A-C, F ). Total length 3.88. Carapace 1.57 long 1.14 wide. Abdomen 2.24 long, 1.10 wide. Clypeus 0.02 high. Eye sizes and inter-distances: AME 0.40, ALE 0.23, PLE 0.22, AERW 1.19, PERW 1.17, EFL 1.02. Legs: I 3.13 (0.95, 0.80, 0.75, 0.38, 0.25), II 2.59 (0.75, 0.40, 0.63, 0.53, 0.28), III 2.69 (0.75, 0.38, 0.63, 0.65, 0.28), IV 3.56 (0.93, 0.50, 0.95, 0.88, 0.30). Habitus (Fig. 18F ) similar to that of male except without transverse, white stripe of setae medially on dorsum of abdomen. Epigyne (Fig. 18A-C ): slightly wider than long, with broad, medio-posteriorly located, posteriorly opened hood; copulatory openings located anteriorly, separated from each other by less than hood width; copulatory ducts thick, short, with terminal accessory glands, connected to the middle of anterior margins of spermathecae; spermathecae oval, touching, extending anterolaterally; fertilization ducts originate from antero-inner margins of spermathecae, extending transversely.

Distribution.

Known only from the type locality in Ninh Binh Province, Vietnam.
