Etymology.
The specific name refers to the type locality; noun in apposition.
Diagnosis.
The new species resembles Pholcus huailai Yao, Li & Lu, 2022 ( Lu et al. 2022: 534, S 18, figs S 17 A – D, S 18 A – H) by having a similar uncus (Fig. 4 C View Figure 4 ) and male chelicerae (Fig. 4 D View Figure 4 ), but it can be distinguished by the: procursus with a raised, prolatero-subdistal membranous edge (arrow 1 in Fig. 3 C View Figure 3 vs. absent), the straight distal edge of the sclerotized distal apophysis on the procursus (arrow 1 in Fig. 3 D View Figure 3 vs. curved), epigynal knob column shaped (kn in Fig. 4 A View Figure 4 vs. wedge shaped), vulval anterior arch curved (aa in Fig. 4 B View Figure 4 vs. nearly trapezoidal).
Description.
Male (holotype): Total length 4.95 (5.14 with clypeus), carapace 1.55 long, 1.88 wide, opisthosoma 3.40 long, 1.60 wide. Leg I: 36.07 (9.29, 0.76, 9.10, 14.62, 2.30), leg II: 25.27 (7.12, 0.72, 6.35, 9.55, 1.53), leg III: 18.79 (5.45, 0.67, 4.55, 6.99, 1.13), leg IV: 24.69 (7.24, 0.68, 6.22, 9.10, 1.45); tibia I L / d: 55. Eye interdistances and diameters: PME – PME 0.21, PME 0.14, PME – ALE 0.04, AME – AME 0.04, AME 0.09. Sternum width / length: 1.19 / 0.98. Habitus as in Fig. 4 E, F View Figure 4 . Carapace yellowish, with brown radiating marks and marginal brown bands; ocular area yellowish, with median and lateral brown bands; clypeus yellowish, with brown marks; sternum brown. Legs yellowish, dark brown on patellae and whitish on distal parts of femora and tibiae, with darker rings on subdistal parts of femora and proximal and subdistal parts of tibiae. Opisthosoma yellowish, with dorsal and lateral brown spots. Chelicerae with pair of proximo-lateral apophyses (pa in Fig. 4 D View Figure 4 ), pair of distal apophyses (da in Fig. 4 D View Figure 4 ) with two teeth each, and pair of frontal apophyses (fa in Fig. 4 D View Figure 4 ). Palps as in Fig. 3 A, B View Figure 3 ; trochanter with long (3 × longer than wide), retrolaterally bulged ventral apophysis; femur with retrolatero-proximal protrusion (arrow in Fig. 3 B View Figure 3 ) and indistinct ventral protrusion; tibia with prolatero-ventral protrusion (arrow in Fig. 3 A View Figure 3 ); procursus simple proximally but complex distally, with raised, prolatero-subdistal membranous edge bearing sclerotized apophysis (arrows 1, 2 in Fig. 3 C View Figure 3 ), sclerotized distal apophysis (arrow 3 in Fig. 3 C View Figure 3 ), and one slender and one strong dorsal spines (arrows 2, 3 in Fig. 3 D View Figure 3 ); uncus with scaly edge (u in Fig. 4 C View Figure 4 ); “ pseudo-appendix ” curved (arrow in Fig. 4 C View Figure 4 ); embolus weakly sclerotized, with transparent distal projections (e in Fig. 4 C View Figure 4 ). Retrolateral trichobothrium on tibia I at 6 % proximally; legs with short, vertical setae on tibiae, metatarsi, and tarsi; tarsus I with 31 distinct pseudosegments.
Female (paratype, SYNU -Ar 00417 ): Similar to male, habitus as in Fig. 4 G, H View Figure 4 . Total length 5.12 (5.26 with clypeus), carapace 1.44 long, 1.66 wide, opisthosoma 3.68 long, 2.08 wide; tibia I: 7.18; tibia I L / d: 48. Eye interdistances and diameters: PME – PME 0.23, PME 0.12, PME – ALE 0.05, AME – AME 0.04, AME 0.08. Sternum width / length: 1.05 / 0.94. Clypeus brown. Epigyne posteriorly strongly curved, with lateral brown marks and knob (kn in Fig. 4 A View Figure 4 ). Vulva with curved, sclerotized anterior arch (aa in Fig. 4 B View Figure 4 ) and pair of nearly elliptical pore plates (pp in Fig. 4 B View Figure 4 ).
Variation.
Tibia I in paratype male ( SYNU -Ar 00416 ): 9.23. Tibia I in another paratype female ( SYNU -Ar 00418 ): 7.24.
Habitat.
Underside of overhang on rocky cliffs in mountainous area.
Distribution.
Liaoning; known only from the type locality (Figs 1 View Figure 1 , 2 A View Figure 2 ).
