Figs 1–2 View FIGURE 1 View FIGURE 2 , 31 View FIGURE 31 C–D
Type material. Holotype: male, Tham (cave) Yan Sang Won (14°44.928′N, 101°01.740′E, elevation 130 m), Hin Son Village, Kaeng Koi District, Saraburi, Thailand, 19 October 2014, H. Zhao, Y. Li and Z. Chen leg. Paratypes: 2 females, same data as holotype.
Etymology. The specific name refers to the type locality; adjective.
Diagnosis. This species resembles P. tharnlodensis sp. nov. ( Figs 3–4 View FIGURE 3 View FIGURE 4 ) in having a similar procursus ( Figs 1 View FIGURE 1 A– D) and female genitalia ( Fig. 2 View FIGURE 2 A) but can be distinguished by short eye-stalks on the male ocular area ( Fig. 31 View FIGURE 31 C), by the presence of frontal and distal apophyses on the male chelicerae ( Fig. 2 View FIGURE 2 D), by the presence of a pointed apophysis distally on the uncus ( Fig. 2 View FIGURE 2 C), and by the absence of hooks distally on the appendix ( Fig. 2 View FIGURE 2 C).
Description. Male (holotype): Total length 5.51 (5.93 with clypeus), carapace 1.28 long, 1.36 wide, opisthosoma 4.23 long, 1.39 wide. Leg I: – (11.85 + 0.64 + 11.67 + – + –), leg II: 31.02 (8.40 + 0.63 + 7.76 +13.14 + 1.09), leg III: 20.32 (6.09 + 0.56 + 4.81 + 7.95 + 0.91), leg IV: 26.26 (8.14 + 0.58 + 6.54 + 10.06 + 0.94); tibia I L/d: 93. Distance PME-PME 0.34; diameter PME 0.12; distance PME-ALE 0.05; distance AME-AME 0.03; diameter AME 0.08. Sternum wider than long (0.89/0.67). Habitus as in Figs 2 View FIGURE 2 E–F. Carapace yellowish, with brown marks posteriorly and marginally; ocular area yellowish; sternum yellowish, with radiating marks. Legs yellowish, patellae, distal parts of femora and tibiae, and proximal parts of metatarsus dark brown, subdistal parts of femora and tibiae whitish, darker rings absent. Opisthosoma yellowish, with brown spots dorsally. Ocular area elevated; each eye triad on top of a short, laterally directed eye-stalk, with small median projection between PME ( Fig. 31 View FIGURE 31 C). Thoracic furrow absent. Chelicerae as in Fig. 2 View FIGURE 2 D, with a pair of proximo-lateral apophyses, a pair of black distal apophyses, each with two teeth, and a pair of inconspicuous frontal apophyses. Pedipalps as in Figs 1 View FIGURE 1 A–B; trochanter with a long ventral apophysis; femur with a dorsal apophysis proximally; procursus simple, presence of a ventral membranous process and a prolatero-dorsal spine (arrow in Fig. 1 View FIGURE 1 A); uncus with scales; appendix broad and with scales; embolus weakly sclerotized. Retrolateral trichobothrium of tibia I at 6.5%; legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae.
Female: Similar to male, habitus as in Figs 2 View FIGURE 2 G–H. Total length 6.05 (6.15 with clypeus), carapace 1.50 long, 1.66 wide, opisthosoma 4.55 long, 1.32 wide; tibia I: 10.90; tibia I L/d: 63. Distance PME-PME 0.26; diameter PME 0.12; distance PME-ALE 0.05; distance AME-AME 0.05; diameter AME 0.08. Sternum wider than long (0.98/0.78). Ocular area without eye-stalks and median projections between PME ( Fig. 31 View FIGURE 31 D). External genitalia ( Fig. 2 View FIGURE 2 A) with a small knob. Vulva ( Fig. 2 View FIGURE 2 B) with a sclerotized anterior arch and two oval pore plates.
Distribution. Thailand (Saraburi, type locality; Fig. 32 View FIGURE 32 ).
Natural history. The species was found in the entrance zone of the cave.
