Material examined.

Holotype ♂, 27°26'45.19"N, 114°11'17.53"E, 1223 m, Tupingao area , near Ropeway , Wugong Mountain National Forest Park , Taishan Town , Anfu County, Ji’an City, Jiangxi Province, China, 4 May 2021, K. Liu, Y. Ying, C. Xu & Q. Xiao leg.

Etymology.

The name is taken from the famous Jinding Scenic Spot, which is very close to Tupingao area in the Wugong Mountain National Forest Park; noun in apposition.

Diagnosis.

The male of this species is most similar to that of Synagelides annae Bohdanowicz, 1979 (see Bohdanowicz 1979: 56, figs 14-17) in having a sharp ventral femoral apophysis, an anticlockwise spiral embolus, a C-shaped terminal apophysis with hook-shaped tip, and the mastoid tegular apophysis in retrolateral view, but differs from it in having (Figs 4C-H , 5 ) the posterior cymbium with a long blunt retrolateral apophysis (vs absent), the parallel retrolateral tibial apophysis together with postero-retrolateral cymbial apophysis in retrolateral view (vs. convergent) and thick clavate retrolateral tibial apophysis (vs spine-like) with many scale-like serrations (vs absent). It also resembles those seven species S. birmanicus Bohdanowicz, 1987 (see Bohdanowicz 1987: 84, figs 66-72), S. cavaleriei (Schenkel, 1963) (see Bohdanowicz 1987: 66, figs 1, 2), S. gosainkundicus Bohdanowicz, 1987 (see Bohdanowicz 1987: 78, figs 45, 46), S. kosi Logunov & Hereward, 2006 (see Logunov and Hereward 2006: 285, figs 21, 22), S. martensi Bohdanowicz, 1987 (see Logunov and Hereward 2006: 287, figs 37-40), S. oleksiaki Bohdanowicz, 1987 (see Bohdanowicz 1987: 79, figs 47, 48), and S. walesai Bohdanowicz, 1987 (see Bohdanowicz 1987: 72, figs 23, 24), but it can be easily distinguished from them by the parallel retrolateral tibial apophysis together with postero-retrolateral cymbial apophysis (vs convergent).

Chelicerae (Fig. 4B ) with two promarginal teeth (proximal larger) and one large laminar retromarginal teeth. Sternum (Fig. 4B ) shield-shaped, longer than wide, posterior end arch-shaped, smooth. Leg measurements: I 3.36 (1.07, 0.71, 0.9, 0.36, 0.32); II 2.2 (0.67, 0.32, 0.46, 0.47, 0.28); III 2.33 (0.69, 0.28, 0.5, 0.55, 0.31); IV 2.25 (0.65, 0.28, 0.52, 0.55, 0.25). Femur width: I 0.31; II 0.21; III 0.21; IV 0.18. Leg spination (Fig. 4A, B ): I tipv 1-2-1, rv 1-2-1; Met pv 0-1-1, rv 0-1-1. Pedicel 0.09. Abdomen 1.37 long, 0.83 wide.

Coloration (Fig. 4A, B ). Carapace yellow-brown, anterior part darker than posterior, posteriorly with radial grooves and 12-14 rows of short black setae. Endites yellowish, mottled. Labium yellowish brown, anteriorly with a single row of strong setae, posteriorly mottled. Sternum, yellow, with pale brown mottled spots around margin. Legs: trochanters I-IV yellow, with dark brown stripe; femur I dark yellow-brown, femora II-IV yellow, with prolateral dark brown stripes; patellae, tibiae, and metatarsi yellow, with dark brown lateral stripes; tarsi yellowish, proximal part darker than distal. Abdomen yellowish to dark brown, with three pairs of yellowish stripes in anterior part and one arch-shaped, yellowish stripe on subposterior part; venter yellowish to yellow. Spinnerets yellowish brown, mottled.

Palp (Figs 4C-H , 5 ). Femur with a strongly sharp, tooth-like ventral apophysis. Patella swollen, with a length-width ratio of ca 1.58. Tibia small and narrow, with a long strong clavate retrolateral apophysis which presents many little scale-like serrations on anterior surface and nearly longer than 1/2 length of cymbium, and a dorsal apophysis locking cymbial postero-prolateral apophysis. Cymbium bullet-shaped in dorsal view, with a long, strong, blunt, sclerotized postero-retrolateral and a long, strong, triangular, postero-prolateral apophysis. Tegulum broad, C-shaped extended in ventral view, with a clear mastoid apophysis and a thin sperm duct in retrolateral view. Terminal apophysis arising from antero-retrolateral part of tegulum, strongly sclerotized, Y-shaped in retrolateral view, with abundant little scale-like serrations on antero-retrolateral surface. Embolus with an anticlockwise spiral in ventral view, longer than terminal apophysis, with broad convoluted basal part and whip-shaped apical part.

Female. Unknown.

Comments.

The male of this species is not conspecific with the female of Synagelides triangulatus sp. nov. for the following reasons. Firstly, the male abdomen has the two pairs of white stripes medially (vs a pair of spots and one chevron-shaped yellowish stripe in S. triangulatus ) and the arch-shaped yellowish stripe located subposteriorly (vs absent in S. triangulatus ).

Distribution.

Known only from the type locality in Jiangxi Province, China (Fig. 13 ).
