Eye sizes and their interdistances: PME 0.19, PME–PME 0.29, PME–ALE 0.04, AME 0.13, AME–AME 0.08. Sternum wider than long (1.28/0.95). Habitus as in Fig. 3E–F. 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 dark brown. Legs yellowish, but 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 spots. Chelicerae (Fig. 3D) with pair of proximo-lateral apophyses, pair of distal apophyses without teeth, pair of frontal apophyses and several small median cones (arrowed in Fig. 3D). Pedipalp as in Fig. 2A–B; trochanter with long (longer than wide), retrolaterally strongly bulged ventral apophysis; femur with small retrolatero-proximal apophysis and indistinct ventral protuberance; tibia with prolatero-ventral projection; procursus simple proximally, but complex distally, with curved, prolateral membranous process (arrowed 1 in Fig. 2C), sclerotised prolatero-dorsal apophysis (arrowed 2 in Fig. 2C), slightly sclerotised distal apophysis (arrowed 3 in Fig. 2C), ventral membranous process (arrowed 4 in Fig. 2C) and three slender dorsal spines (arrowed 5 in Fig. 2C); uncus with scales, medially protruding (arrowed in Fig. 3C); appendix hooked, with subdistal membranous branch (Fig. 3C); embolus weakly sclerotised, with some transparent distal projections (Fig. 3C). Retrolateral trichobothrium of tibia I at 5% proximally; legs with short vertical setae on tibiae, metatarsi and tarsi, without spines or curved setae; tarsus I with 27 distinct pseudo-segments.

Pholcus bajia sp. nov. A Paratype female, external genitalia, ventral view; B Paratype female, vulva, dorsal view; C Holotype male, bulbal apophyses, prolateral view, arrow points at median protrusion; D Holotype male, chelicerae, frontal view, arrow points at median cones; E Holotype male, habitus, dorsal view; F Holotype male, habitus, lateral view; G Paratype female, habitus, dorsal view; H Paratype female, habitus, ventral view. a = appendix, da = distal apophysis, e = embolus, fa = frontal apophysis, pa = proximo-lateral apophysis, pp = pore plate, u = uncus. Scale bars: 0.20 mm (A–D), 1.00 mm (E–H).

Female: Similar to male, habitus as in Fig. 3G–H. Total length 4.53 (4.74 with clypeus), carapace 1.25 long, 1.60 wide, opisthosoma 3.28 long, 1.59 wide; tibia I: 7.40; tibia I L/d: 49. Eyes sizes and their interdistances: PME 0.14, PME–PME 0.21, PME–ALE 0.05, AME 0.09, AME–AME 0.04. Sternum wider than long (1.03/0.75). Sternum yellowish, with brown marks. External female genitalia (Fig. 3A) dark brown, slightly curved postero-medially, with wedge-shaped knob. Vulva (Fig. 3B) with crescent-shaped, sclerotised anterior arch and pair of nearly elliptic pore plates.

Variation: Tibia I in the paratype male (SYNU-Ar00248): 11.20. Tibia I in a paratype female (SYNU-Ar00250): 8.20.

The species resembles P. harveyi Zhang & Zhu, 2009 (see Zhang and Zhu 2009: fig. 15; Yao and Li 2012: figs. 75–76) by having similar male cheliceral apophyses (Fig. 3D), but can be easily distinguished by its procursus with curved, prolateral membranous process (arrowed 1 in Fig. 2C; absent in P. harveyi) and ventral membranous process (arrowed 4 in Fig. 2C; ventral sclerotised apophysis in P. harveyi), by uncus medially protruding (arrowed in Fig. 3C; not protruding in P. harveyi), by appendix with subdistal membranous branch (Fig. 3C; absent in P. harveyi), by external female genitalia nearly anchor-shaped (Fig. 3A; nearly triangular in P. harveyi) and by vulval anterior arch crescent-shaped (Fig. 3B; nearly eyebrow-shaped in P. harveyi).

The specific name refers to the type locality and is a noun in apposition.

China (Hebei, type locality; Fig. 1).

The species was found on rock walls.
