Type material. Holotype: male, Lingguan Cave (33°12.832′N, 112°11.377′E, elevation 336 m), Lingguandian Village, Erlong Town, Zhenping County, Nanyang, Henan, China, 22 May 2014, Y. Li and J. Liu leg. Paratypes: 3 males 4 females, same data as holotype.
Etymology. The specific name refers to the type locality; adjective.
Diagnosis. This species resembles P. parayichengicus Zhang & Zhu, 2009 (see Zhang & Zhu 2009: 62, figs 33–34 and Yao & Li 2012: 29, figs 140–141) with similar male chelicerae (Fig. 18 D), bulbal apophyses (Fig. 18 C) and epigynum (Fig. 18 A) but can be distinguished by the absence of small retrolateral apophyses subdistally on the long male pedipalpal trochanteral apophyses (Figs 17 A–B), by the small, membranous prolatero-distal process (arrow 1 in Fig. 17 C) and the very small, sclerotized ventro-subdistal apophysis on the procursus (arrow in Fig. 17 D) and by the curved vulval pore plates (Fig. 18 B).
Description. Male (holotype): Total length 5.52 (5.96 with clypeus), carapace 1.56 long, 1.90 wide, opisthosoma 3.96 long, 1.78 wide. Leg I: 42.98 (11.15 + 0.80 + 10.64 + 18.01 + 2.38), leg II: 29.58 (8.27 + 0.76 + 7.48 + 11.67 + 1.40), leg III: 22.25 (6.41 + 0.70 + 5.32 + 8.72 + 1.10), leg IV: 28.96 (8.46 + 0.68 + 7.24 + 11.22 + 1.36); tibia I L/d: 63. Distance PME-PME 0.23; diameter PME 0.14; distance PME-ALE 0.06; distance AME- AME 0.07; diameter AME 0.11. Sternum wider than long (1.25/0.91). Habitus as in Figs 18 E–F. Carapace yellowish, with brown radiating marks extending to ocular area and brown bands marginally; ocular area yellowish; clypeus brown; sternum brown with yellowish marks medially. Legs yellowish, femora (subproximally and subdistally) and tibiae (subproximally and subdistally) with slightly darker rings. Opisthosoma yellowish, with small spots dorsally and laterally. Ocular area elevated, without eye stalks (as in P. gonggarensis sp. nov., cf. Fig. 27 C). Thoracic furrow absent. Chelicerae as in Fig. 18 D, with a pair of proximo-lateral apophyses, a pair of black distal apophyses, and a pair of frontal apophyses. Pedipalps as in Figs 17 A–B; trochanter with a ventral apophysis; femur with a ventral ridge; tibia with a projection prolaterally; procursus simple proximally but complex distally, with a spine-like prolatero-ventral apophysis medially (arrow 2 in Fig. 17 C), a small, membranous prolatero-distal process (arrow 1 in Fig. 17 C) and a small, sclerotized ventro-subdistal apophysis (arrow in Fig. 17 D); uncus with a scaly edge; appendix hooked, with a small branch subdistally; embolus weakly sclerotized. Retrolateral trichobothrium of tibia I at 8%; legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae; tarsus I with 23 distinct pseudosegments.
Female: Similar to male, habitus as in Figs 18 G–H. Total length 5.13 (5.51 with clypeus), carapace 1.41 long, 1.60 wide, opisthosoma 3.72 long, 2.64 wide; tibia I: 8.01; tibia I L/d: 57. Distance PME-PME 0.21; diameter PME 0.11; distance PME-ALE 0.06; distance AME-AME 0.06; diameter AME 0.09. Sternum wider than long (1.06/ 0.78). Ocular area with brown marks; Epigynum (Fig. 18 A) with a knob. Vulva (Fig. 18 B) with a sclerotized anterior arch and two curved pore plates.
Distribution. China (Hena, type locality; Fig. 28).
Natural History. The species was found on the wall in the entrance zone of the cave.
