Type material.

Holotype ♂ ( TRU - JS 0781 ), China: • Guangxi Zhuang Autonomous Region, Laibing City, Jinxiu Yao Autonomous County, Yinshan Park (24°10.07'N, 110°14.48'E, ca 1310 m), 8. XI. 2021, A. L. He et al. leg GoogleMaps . Paratypes • 3 ♂ 7 ♀ ( TRU - JS 0782–0791 ), same data as for holotype GoogleMaps .

Etymology.

The specific name is after Mr. Liu Xuande, who is the first emperor of Shu during the Three Kingdoms of ancient China; noun (name) in the genitive case.

Diagnosis.

The male of Synagelides xuandei sp. nov. is similar to S. huangxin Lin & Li, 2024 in general shape of the palp, but can be distinguished by the median apophysis (MA), which is widest distally and has a base elongate-oval lamellar branch (Fig. 33 B, E View Figure 33 ) vs almost tapered at distal half and lacking similar branch ( Lin et al. 2024 b: fig. 47 B). The female of this species resembles that of S. subgambosus Wang, Mi, Irfan & Peng, 2020 in general shape of epigyne, especially the rugulose atrium (At), but can be easily distinguished the copulatory ducts ( CD), which are strongly curved at proximal half (Fig. 34 B – D View Figure 34 ) vs straight ( Wang et al. 2020: fig. 12 B, C).

Description.

Male (Figs 33 View Figure 33 , 34E, F, H – J View Figure 34 ). Total length 4.63. Carapace 2.07 long, 1.48 wide. Abdomen 2.52 long, 1.22 wide. Eye sizes and interdistances: AME 0.50, ALE 0.27, PLE 0.26, AERW 1.46, PERW 1.48, EFL 1.15. Legs: I 5.86 (1.85, 1.68, 1.45, 0.58, 0.30), II 3.72 (1.13, 0.58, 0.95, 0.73, 0.33), III 3.91 (1.15, 0.53, 0.95, 0.95, 0.33), IV 5.27 (1.38, 0.68, 1.43, 1.35, 0.43). Carapace mainly red-brown, covered with thin setae. Legs mainly red-brown, with four and two pairs of ventral spines on tibiae and metatarsi I. Dorsum of abdomen dark brown, with pair of longitudinal, anterolateral, pale setal stripes and pair of oblique, median, pale setal patches; venter pale, with broad, central dark brown patch.

Palp (Fig. 33 A – E View Figure 33 ): femur length / width ratio ca 2.1; patella ~ 1.6 × longer than wide in retrolateral view; tibia short, with sub-triangular dorsal apophysis ( DTA) and slender, S-shaped retrolateral apophysis ( RTA); cymbium ~ 1.8 × longer than wide, with prolateral ridged portion (CR), blunt retrolateral apophysis ( RCA) and tapered baso-dorsal apophysis ( DCA) with pointed end; tegulum swollen; median apophysis (MA) large, broadened and forming mesal ridge, with base, elongate-oval lamellar branch extended ventrally; embolus (E) forming half-round disc at base, then tapered and curved into rather blunt tip.

Female (Fig. 34 A – D, G View Figure 34 ). Total length 4.88. Carapace 2.02 long, 1.39 wide. Abdomen 2.72 long, 1.47 wide. Eye sizes and inter-distances: AME 0.50, ALE 0.28, PLE 0.26, AERW 1.51, PERW 1.49, EFL 1.21. Legs: I 4.83 (1.50, 1.23, 1.25, 0.55, 0.30), II 3.63 (1.10, 0.55, 0.90, 0.78, 0.30), III 3.94 (1.13, 0.53, 0.95, 0.98, 0.35), IV 5.40 (1.45, 0.70, 1.40, 1.40, 0.45). Habitus (Fig. 34 G View Figure 34 ) similar to that of male except paler and with much shallow similar patterns.

Epigyne (Fig. 34 A – D View Figure 34 ) slightly longer than wide, with broad posterior fold (F) ~ 1 / 3 atrial width; atrium (At) crinkly, occupied anterior 3 / 5 and separated by narrow septum (Se), with pair of lateral ridges (AR); copulatory openings (CO) invisible; copulatory ducts ( CD) strongly curved at proximal, and connected to inner portions of spermathecae, with bar-shaped, terminal accessory glands ( AG); spermathecae (S) touching each other, with spherical inner portions and transversely extended, elongate-oval outside portions.

Distribution.

Known only from the type locality in Guangxi, China (Fig. 47 View Figure 47 ).
