Etymology. The species is named after N'Doul, a character in the third part of JoJo's Bizarre Adventure, Stardust

Crusaders; noun in apposition.

Diagnosis. The female of the new species resembles T. sinanensis ( Zhou et al., 2023) by the broad copulatory opening and triangular epigynal teeth, but it can be distinguished by the spermathecal heads located medially (vs. anteriorly) and spermathecae with complex internal ducts (vs. absent).

Description. Female (holotype). Total length 10.84, carapace 4.35 long, 2.85 wide, opisthosoma 6.47 long, 2.35 wide. Eyes vestigial. Eye sizes and interdistances: AME absent, ALE 0.13, PME 0.08, PLE 0.14, PME–PME 0.23, PME–PLE 0.22, ALE–PME 0.12, ALE–PLE 0.06. Chelicerae with 2 promarginal and 2 retromarginal teeth. Leg measurements: I 17.49 (4.48, 5.71, 4.29, 3.01), II 20.45 (4.36, 5.13, 4.74, 6.22), III 18.20 (4.29, 4.17, 4.36, 5.38), IV 11.67 (3.01, 2.95, 2.63, 3.08).

Coloration ( Fig. 3A ). Carapace yellow-brown. Cephalic region brown to dark brown, thoracic region pale yellow. Cervical and radial furrows distinct. Chelicerae dark brown. Endites and labium brown. Sternum yellowish brown. Legs brown with black setae. Opisthosoma oval, gray, without any pattern. Spinnerets gray.

Epigyne ( Fig. 1 ). Epigynal plate 2 times longer than wide. Epigynal teeth equilateral triangular, strongly sclerotized, located anteriorly. Atrium butterfly shaped, median plate anterior edge procurved. Copulatory openings broad medially. Copulatory ducts partially membranous, curved before reaching ellipsoidal spermathecae. Spermathecal heads obvious. Spermathecae with complex internal ducts. Fertilization duct directed at 2:00-o’clock-position from spermatheca.

Male. Unknown.

Material examined. Holotype ♀ (IZCAS-Ar44790), China: Guangxi, Hechi City, Huanjiang Maonan Autonomous Co., Dacai Township, Shenlonggong Cave (24.7707°N, 108.3898°E), 1.VIII.2023, Shanmi Zheng and Haolin Mo leg.
