Etymology. The specific epithet is derived from type locality; adjective.

Diagnosis. Wuliphantes dahonghaiensis sp. nov. resembles W. trigyrus Irfan, Wang & Zhang, 2023 in having similar characters of copulatory organs ( Figs 8A–D , 9A–E ; Irfan et al. 2023b, figs 61A–D, 62A–C), but can be distinguished by the embolus with one coil ( Fig. 8A ; vs with 3 coils); base of protegulum (PT) lacking teeth ( Fig. 8B ; vs with about 8 small teeth). Copulatory ducts with about 3 coils before entering the spermathecae ( Fig. 9D ; vs with about 7 coils); spermathecae bean-shaped in anterior view ( Fig. 9C ; vs cone-shaped).

Description. Male (holotype, Fig. 10A, B ): total length 2.15; carapace 1.02 long, 0.81 wide, yellowish brown, cephalic region slightly elevated, cervical and radial grooves distinct. Clypeus 0.14 high. Chelicerae with 3 promarginal and 3 retromarginal teeth. Sternum yellowish green, slightly longer than wide. Eyes: AER recurved, PER straight, slightly wider than AER. Eye sizes and interdistances: AME 0.06, ALE 0.09, PME 0.09, PLE 0.09, AME–AME 0.02, PME–PME 0.03, AME–ALE, 0.04, PME–PLE 0.05, AME–PME 0.08, ALE–ALE 0.36, PLE– PLE 0.39, ALE–PLE contiguous. Length of legs: I 4.9 (1.39, 0.28, 1.24, 1.25, 0.74), II 4.37 (1.25, 0.27, 1.17, 1.06, 0.62), III 3.18 (0.93,0.26, 0.75, 0.72,0.49), IV 4.00 (1.21, 0.24., 1.05, 0.98, 0.63). TmI 0.26. Opisthosoma 1.14 long, 0.72 wide, oval, dorsally with 5 chevrons, dusky gray, ventral side greenish.

Palp ( Fig. 8A–D ). Femur unmodified, longer than both patella and tibia. Patella as long as wide, shorter than tibia. Tibia conical, with 2 retrolateral trichobothria. Paracymbium (PC) U-shaped, simple, proximal end wide with thick setae, distal arm slightly curved with blunt tip. Cymbium leaf-shaped in ventral view, gradually tappering towards apex; tegulum longer than wide in retrolateral view with well-developed protegulum bulge on ectal side; embolic plate with a short finger-shaped prolateral arm (DPE) long median arm (VPE) extending towards distal end of cymbium with claw like tip and retrolateral arm (RPE) triangular with blunt tip; median membrane (MM) distinct; embolus forming 1.75 coils, originates from center position.

Female (paratype, SWUC-T-LIN-32-02, Fig. 10C, D ): total length 1.84; carapace 0.78 long, 0.60 wide, cephalic region slightly elevated, yellowish brown with gray pattern, cervical and radial grooves distinct. Clypeus 0.12 high. Chelicerae with 3 promarginal and 3 retromarginal teeth. Sternum longer than wide, yellowish green. Eyes: AER recurved, PER slightly procurved, slightly wider than AER. Eye sizes and interdistances: AME 0.05, ALE 0.08, PME 0.07, PLE 0.08, AME–AME 0.02, PME–PME 0.03, AME–ALE, 0.03, PME–PLE 0.04, AME–PME 0.07, ALE–ALE 0.29, PLE–PLE 0.32, ALE–PLE contiguous. Length of legs: I 3.66 (0.96, 0.24, 0.93,0.88, 0.65), II 3.48 (0.94, 0.23, 0.88, 0.83, 0.60), III 2.79 (0.79, 0.22, 0.66, 0.63, 0.49), IV 3.64 (1.03,0.22, 0.93, 0.89, 0.57). TmI 0.23. Opisthosoma 1.16 long, 0.76 wide, oval, greenish, dorsally with 5 chevrons, ventral side greenish black.

Epigyne ( Fig. 9A–E ). Epigynal plate wider than long; ventral plate (VP) unmodified; dorsal plate (DP) somewhat rectangular; copulatory openings (CO) located mid-laterally; copulatory ducts (CD) forming 3 coils before joining spermathecae; spermathecae (S) bean-shaped; fertilization ducts extending mesally.

Distribution. Known only from the type localities in Jiangjin District, Chongqing ( Fig. 13 ).
