Holotype ♂ ( TRU - JS 0792 ), 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 . Paratypes • 1 ♂ ( TRU - JS 0793 ), same data as for holotype ; • 1 ♂ ( TRU - JS 0794 ), Shengtangshan Scenic Area ( 23°58.05'N , 110°6.53'E , ca 1520 m ), 11. X. 2021 , A. L. He et al. leg . Etymology. The specific name is after Mr. Zhang Yide, who is one of the famous Shu Generals in the Three Kingdoms of ancient China ; noun (name) in the genitive case. Diagnosis. Synagelides yidei sp. nov. can be easily distinguished from other known male congeners by the bifurcated dorsal tibial apophysis ( DTA ) (Fig. 35 B – D ) vs absent or not bifurcated in congeners (see Metzner 2024 ). Description. Male (Figs 35 , 36 ). Total length 3.93. Carapace 1.76 long, 1.34 wide. Abdomen 2.23 long, 0.95 wide. Eye sizes and interdistances: AME 0.42, ALE 0.23, PLE 0.21, AERW 1.18, PERW 1.30, EFL 0.97. Legs: I 7.13 (2.25, 2.05, 1.63, 0.75, 0.45), II 3.51 (1.03, 0.55, 0.88, 0.70, 0.35), III 3.57 (0.98, 0.53, 0.88, 0.83, 0.35), IV 4.79 (1.28, 0.70, 1.30, 1.13, 0.38). Carapace mainly yellow, with pair of indistinct dark patches anteriorly on square cephalon. Legs slender, bear four and two pairs of ventral spines on tibiae and metatarsi I. Abdomen slightly constricted medially, dorsum dark brown posteriorly, with two pairs of median, yellow muscle depressions; venter pale, with pair of central, dotted lines. Figure 35.

Palp (Fig. 35 A – E ): femur length / width ratio ca 1.68; patella ~ 1.5 × longer than wide in retrolateral view; dorsal tibial apophysis ( DTA ) bifurcated with two short, blunt rami; retrolateral tibial apophysis ( RTA ) tapered, slender,> 1 / 2 cymbial length, and pointed apically; cymbium with prolateral ridged portion ( CR ), strongly sclerotized, blunt baso-dorsal apophysis ( DCA ) and prolateral apophysis ( PCA ); tegulum swollen; median apophysis ( MA ) irregular, retrolateral to embolus; embolus (E) forming disc at base, then twisted into blunt end.
