Type material.

Holotype ♂(IZCAS-Ar40931), China: Yunnan: Xishuangbanna, Mengla County, Menglun Township, XTBG, Leprosy Village, 21.8932N, 101.2883E, elevation ca 550 m, 27.IX.2017, Zhigang Chen, Yunchun Li, Qingyuan Zhao and Jincheng Liu leg. Paratypes 6♂7♀(IZCAS-Ar40932-Ar40944), same data as holotype.

Etymology.

The species is named after the late Norman I. Platnick (1951-2020, see Li 2020b) to commemorate his immense contribution to arachnology; noun (name) in genitive case.

Diagnosis.

Synagelides platnicki sp. nov. resembles S. lushanensis Xie & Yin, 1990 by having the same shaped median apophysis and a coiled embolus but differs by the following: the length of the RTA is four times as long as the length of the cymbium (vs. two times the length in S. lushanensis ), the dorsal tibial apophysis is absent (vs. present in S. lushanensis ) and the retrolateral median apophysis is L-shaped in retrolateral view (vs. straight in S. lushanensis ); in the female, the hood of the epigyne is as long as wide (vs. two times longer than wide in S. lushanensis ), and the copulatory duct is coiled 360° (vs. S-shaped in S. lushanensis ).

Description.

Male (Figs 16 , 17C, D, F, G ). Total length 3.22. Carapace 1.50 long, 0.99 wide. Abdomen 1.85 long, 0.75 wide. Clypeus 0.03 high. Eye sizes and inter-distances: AME 0.35, ALE 0.20, PLE 0.19, AERW 0.98, PERW 1.03, EFL 0.90. Legs: I 3.93 (1.18 + 1.02 + 1.00 + 0.44 + 0.29), II 2.14 (0.63 + 0.24 + 0.52 + 0.49 + 0.26), III 2.44 (0.71 + 0.26 + 0.58 + 0.60 + 0.29), IV 3.24 (0.89 + 0.36 + 0.84 + 0.79 + 0.36). Carapace red-brown, widest between coxae II and III, covered with white setae. Clypeus dark brown. Fovea subtriangular. Chelicerae yellow-brown, with two promarginal teeth and one retromarginal tooth. Endites yellow-brown. Sternum brown, covered with thin setae. Femur of leg I red, other femora with black pattern ventrally. Abdomen elongated oval, dorsum with two pairs of white dorso-lateral spots, covered with white setae on the spots and laterally; venter black.

Palp (Fig. 16A-F ) femur brown, approximately three times longer than wide, with ventral median apophysis; patella brown, almost as long as wide, with ventral bulge; tibia wider than long, with RTA tapering towards tip, slightly longer than tibia, tip slightly bent ventrally then dorsally; cymbium flattened, widest medially; bulb widest at base; embolus coiled 360°, median apophysis with serrated apophysis, terminus blunt; retrolateral median apophysis L-shaped.

Female (Fig. 17A, B, E ). Total length 3.68. Carapace 1.48 long, 0.98 wide. Abdomen 2.14 long, 1.03 wide. Clypeus 0.02 high. Eye sizes and inter-distances: AME 0.33, ALE 0.20, PLE 0.20, AERW 1.03, PERW 1.03, EFL 0.85. Legs: I 2.91 (0.88 + 0.69 + 0.70 + 0.37 + 0.27), II 1.99 (0.61 + 0.23 + 0.47 + 0.41 + 0.27), III 2.14 (0.61 + 0.25 + 0.49 + 0.51 + 0.28), IV 2.73 (0.75 + 0.30 + 0.70 + 0.69 + 0.29). Habitus similar to that of male.

Epigyne (Fig. 17A, B ) wider than long, with anterior hood, copulatory openings located medially; copulatory ducts visible on epigynal surface, coiled 360°, connecting with anterior edge of spermathecae; spermathecae spherical, touching medially; fertilization ducts originating from the median anterior edge of spermathecae, extending almost transversely.

Distribution.

Known only from the type locality in Yunnan, China.
