Type Material.
Holotype ♂ (TRU - JS 0802), China: • Yunnan Province, Wenshan City, Wenshan National Nature Reserve, Bozhushan (23°22.19'N, 103°55.17'E, ca 2730 m), 14. V. 2024, C. Wang et al. leg. Paratypes • 1 ♂ 2 ♀ (TRU - JS 0803–0805), same data as for holotype.
Etymology.
The specific name is after Mr. Zhao Zilong, who is one of the famous Shu Generals in the Three Kingdoms of ancient China; noun (name) in the genitive case.
Diagnosis.
Synagelides zilongi sp. nov. resembles that of S. jingzhao Yang, Zhu & Song, 2007 in the habitus and general shape of copulatory organs, but can be easily distinguished by the following: 1) retrolateral tibial apophysis (RTA) ~ 1 / 2 of cymbial length in retrolateral view (Fig. 39 B) vs ~ 3 / 5 of cymbial length (Yang et al. 2007: fig. 1 F); 2) epigynal hood (H) ~ 3 × longer than wide (Fig. 40 A – D) vs just slightly longer than wide (Yang et al. 2007: fig. 1 B); 3) presence of four pairs of ventral spines on tibiae I (Fig. 40 I) vs five pairs (see the description in Yang et al. 2007: 1).
Description.
Male (Figs 39, 40E, F, H – J). Total length 3.18. Carapace 1.43 long, 1.09 wide. Abdomen 1.72 long, 0.78 wide. Eye sizes and inter-distances: AME 0.34, ALE 0.19, PLE 0.18, AERW 1.02, PERW 1.11, EFL 0.83. Legs: I 4.54 (1.38, 1.20, 1.13, 0.50, 0.33), II 2.53 (0.75, 0.40, 0.60, 0.50, 0.28), III 2.59 (0.75, 0.38, 0.60, 0.58, 0.28), IV 3.49 (0.95, 0.48, 0.93, 0.83, 0.30). Carapace yellow-brown to dark, with longitudinal, dark, thin stripe centrally on cephalon. Legs slender, with four and two pairs of ventral spines on patellae and metatarsi I. Dorsum of abdomen dark, with pair of anterolateral, pale dots followed by paired, dark yellow dots, and inconsistent, transverse, white stripes bearing sparse white setae medially; venter pale, mingled with dark, with longitudinal, dark stripe extending from epigastric groove to posterior 1 / 3.
Palp (Fig. 39 A – E): femur length / width ratio ca 1.67; patella ~ 1.5 × longer than wide; tibia ~ 1 / 3 patellar length; dorsal tibial apophysis (DTA) strongly sclerotized, directed towards ca 1: 30 o’clock position apically in retrolateral view; retrolateral tibial apophysis (RTA) tapered into pointed tip reaches base of median apophysis (MA), with small, spinous ramus located on ventral margin of anterior 1 / 3; cymbium with prolateral ridged portion (CR), and blunt baso-dorsal apophysis (DCA); tegulum swollen; median apophysis (MA) irregular, retrolateral to embolus; embolus (E) broadened at base, twisted into blunt end.
Female (Fig. 40 A – D, G). Total length 4.45. Carapace 1.88 long, 1.39 wide. Abdomen 2.58 long, 1.36 wide. Eye sizes and inter-distances: AME 0.42, ALE 0.24, PLE 0.21, AERW 1.29, PERW 1.42, EFL 1.01. Legs: I 4.27 (1.28, 0.98, 1.13, 0.55, 0.33), II 2.89 (0.88, 0.45, 0.68, 0.58, 0.30), III 3.07 (0.88, 0.43, 0.73, 0.73, 0.30), IV 4.27 (1.20, 0.58, 1.13, 1.03, 0.33). Habitus (Fig. 40 G) similar to that of male except paler and wider abdomen.
Epigyne (Fig. 40 A – D) ~ 1.15 × longer than wide, with tube-shaped anterior hood (H) ~ 3 × longer than wide; atrium (At) oval, with pair of arc-shaped lateral ridges (AR); septum (Se) wide, narrowest medially; copulatory openings (CO) baso-lateral to narrowest portion of septum; copulatory ducts (CD) slender, curved into U-shape at anterior 2 / 3, with short, bar-shaped accessory glands (AG); spermathecae (S) elongate-oval, touching each other, ~ 1.8 × longer than wide.
Distribution.
Known only from the type locality in Yunnan, China (Fig. 48).
