description: Pholcus jingyangensis Yao & Li sp. nov.
Figs 3–4
Type material. Holotype: male, Zhangjiashan Scenic Spot (34°38.703′N, 108°34.947′E, elevation 428 m), Wangqiao Town, Jingyang County, Xian, Shaanxi, China, 4 October 2013, Y. Li and J. Liu leg. Paratypes: 2 females, same data as holotype.
Etymology. The specific name refers to the type locality; adjective.
Diagnosis. This species resembles P. chang Yao & Li, 2012 (see Yao & Li 2012: 12, figs 43–46) with similar male chelicerae (Fig. 4 D), uncus (Fig. 4 C) and epigynum (Fig. 4 A) but can be distinguished by the presence of a distinct ventral protuberance proximally on the male pedipalpal femur (Figs 3 A–B), by the short procursus (Figs 3 A–B), by the presence of a large pointed apophysis distally on the appendix (arrow in Fig. 4 C) and by the nearly semicircular vulval pore plates (Fig. 4 B). This species also resembles P. manueli Gertsch, 1937 (see Zhang & Zhu 2009: 52, fig. 26 and Huber 2011b: 361, figs 1655–1656, 1671–1672, 1729–1741) with similar male chelicerae (Fig. 4 D), appendix, embolus (Fig. 4 C) and epigynum (Fig. 4 A) but can be distinguished by the presence of a distinct ventral protuberance proximally on the male pedipalpal femur (Figs 3 A–B), by the absence of pointed prolateral apophyses subdistally on the procursus (Fig. 3 C), by the large uncus (Fig. 4 C), and by the nearly semicircular vulval pore plates (Fig. 4 B).
Description. Male (holotype): Total length 4.21 (4.51 with clypeus), carapace 1.33 long, 1.40 wide, opisthosoma 2.81 long, 1.28 wide. Leg I: 29.95 (7.76 + 0.68 + 7.95 + 11.28 + 2.28), leg II: 21.49 (6.15 + 0.63 + 5.77 +7.69 + 1.25), leg III: 20.96 (6.15 + 0.60 + 5.64 + 7.44 + 1.13), leg IV: 15.77 (4.64 + 0.60 + 4.00 + 5.77 + 0.94); tibia I L/d: 54. Distance PME-PME 0.20; diameter PME 0.11; distance PME-ALE 0.04; distance AME- AME 0.03; diameter AME 0.08. Sternum wider than long (0.95/0.81). Habitus as in Figs 4 E–F. Carapace yellowish, with brown marks medially; ocular area yellowish; sternum yellowish, with radiating brown marks. Legs yellowish, femora (subdistally) and tibiae (subproximally) with darker rings. Opisthosoma yellowish. Ocular area elevated, without eye stalks (as in P. gonggarensis sp. nov., cf. Fig. 27 C). Thoracic furrow absent. Chelicerae as in Fig. 4 D, with a pair of proximo-lateral apophyses, a pair of distal apophyses, each with three cone-shaped teeth, and a pair of frontal apophyses. Pedipalps as in Figs 3 A–B; trochanter with a ventral apophysis; femur with a dorsal apophysis proximally and a distinct ventral protuberance; procursus simple proximally but complex distally; uncus with scales; appendix swollen, with a large pointed apophysis distally (arrow in Fig. 4 C); embolus weakly sclerotized, with some transparent projections distally. 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 27 distinct pseudosegments.
Female: Similar to male, habitus as in Figs 4 G–H. Total length 4.55 (4.81 with clypeus), carapace 1.33 long, 1.42 wide, opisthosoma 3.13 long, 1.56 wide; tibia I: 7.37; tibia I L/d: 32. Distance PME-PME 0.22; diameter PME 0.11; distance PME-ALE 0.03; distance AME-AME 0.02; diameter AME 0.08. Sternum wider than long (1.03/ 0.83). Epigynum (Fig. 4 A) with a knob. Vulva (Fig. 4 B) with a sclerotized anterior arch and two nearly semicircular pore plates.
Distribution. China (Shaanxi, type locality; Fig. 28).
Natural History. The species was found on the rock walls.
