Type material.
Holotype: China • ♂; Hebei, Qinhuangdao, Funing District, Daxinzhai Town, Bingtangyu Scenic Spot ; 40.106112°N, 119.356216°E; alt. 250 m; 20 Jul. 2024; Z. Yao, J. Li & M. Yan leg.; SYNU -Ar 00437 GoogleMaps . Paratypes: China • 2 ♂; same data as for the holotype; SYNU -Ar 00438 –39 GoogleMaps • 3 ♀; same data as for the holotype; SYNU -Ar 00440 –42 GoogleMaps .
Etymology.
The specific name refers to the type locality (Qin is a short name for Qinhuangdao); noun in apposition.
Diagnosis.
The new species resembles Pholcus kuaile Yao, Li & Lu, 2022 ( Lu et al. 2022: 534, S 21, figs S 22 A – D, S 23 A – H) by having similar male chelicerae (Fig. 14 D View Figure 14 ) and a vulval anterior arch (Fig. 14 B View Figure 14 ), but it can be distinguished by the: procursus without an angular ventral sclerite (Fig. 13 B View Figure 13 vs. present) and without a distal membranous process (Fig. 13 C View Figure 13 vs. present), uncus with two distal apophyses (arrows 2, 3 in Fig. 14 C View Figure 14 vs. one), epigynal plate 3 × longer than wide (Fig. 14 A View Figure 14 vs. 8 ×), vulval pore plates widely separated and same size as knob (pp in Fig. 14 B View Figure 14 vs. close to each other and 8 × larger than knob).
Description.
Male (holotype): Total length 4.64 (4.80 with clypeus), carapace 1.28 long, 1.60 wide, opisthosoma 3.36 long, 1.42 wide. Leg I: 40.72 (10.06, 0.75, 10.00, 17.25, 2.66), leg II: 26.95 (7.31, 0.63, 6.47, 10.96, 1.58), leg III: 18.78 (5.32, 0.58, 4.50, 7.25, 1.13), leg IV: 24.34 (6.60, 0.59, 6.09, 9.68, 1.38); tibia I L / d: 77. Eye interdistances and diameters: PME – PME 0.20, PME 0.13, PME – ALE 0.04, AME – AME 0.05, AME 0.08. Sternum width / length: 1.05 / 0.93. Habitus as in Fig. 14 E, F View Figure 14 . Carapace yellowish, with brown radiating marks and marginal brown bands; ocular area yellowish, with median and lateral brown bands; clypeus brownish; sternum yellowish, with brown marks. 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. 14 D View Figure 14 ), pair of distal apophyses (da in Fig. 14 D View Figure 14 ) with two teeth each, and pair of frontal apophyses (fa in Fig. 14 D View Figure 14 ). Palps as in Fig. 13 A, B View Figure 13 ; trochanter with long (8 × longer than wide), retrolaterally strongly bulged ventral apophysis; femur with retrolatero-proximal protrusion (arrow in Fig. 13 B View Figure 13 ) and distinct ventral protrusion; tibia with prolatero-ventral protrusion (arrow in Fig. 13 A View Figure 13 ); procursus simple proximally but complex distally, with raised prolatero-subdistal edge bearing spine-shaped apophysis (arrow in Fig. 13 C View Figure 13 ), and two strong dorsal spines (arrow in Fig. 13 D View Figure 13 ); uncus with scales, proximal apophysis (arrow 1 in Fig. 14 C View Figure 14 ), and two distal apophyses (arrows 2, 3 in Fig. 14 C View Figure 14 ); “ pseudo-appendix ” semi-transparent (arrow 4 in Fig. 14 C View Figure 14 ); embolus weakly sclerotized, with transparent distal projections (e in Fig. 14 C View Figure 14 ). Retrolateral trichobothrium on tibia I at 3 % proximally; legs with short, vertical setae on tibiae, metatarsi, and tarsi; tarsus I with 40 distinct pseudosegments.
Female (paratype, SYNU -Ar 00440 ): Similar to male, habitus as in Fig. 14 G, H View Figure 14 . Total length 4.71 (4.85 with clypeus), carapace 1.39 long, 1.56 wide, opisthosoma 3.32 long, 1.76 wide; tibia I: 8.15; tibia I L / d: 54. Eye interdistances and diameters: PME – PME 0.18, PME 0.14, PME – ALE 0.04, AME – AME 0.05, AME 0.08. Sternum width / length: 0.96 / 0.90. Clypeus brown. Epigyne posteriorly straight, with knob (kn in Fig. 14 A View Figure 14 ). Vulva with nearly U-shaped, sclerotized anterior arch (aa in Fig. 14 B View Figure 14 ) and pair of nearly elliptical pore plates (pp in Fig. 14 B View Figure 14 ).
Variation.
Tibia I in two paratype males ( SYNU -Ar 00438 –39): 10.26, 10.64. Tibia I in the other two paratype females ( SYNU -Ar 00441 –42): 8.08, 8.33.
