Type material. Holotype: male (Ar29674), Dilarang Masuk (2°02.150′S, 113°46.743′E, elevation 24 m), Tumbang Tahai, Central Kalimantan, Indonesia, 13 August 2014, H. Zhao and Z. Yao leg. Paratypes: 1 male and 3 females (Ar 29675–29678), same data as holotype.
Etymology. The specific name is a Chinese pinyin word for leaf (shù yè), in reference to the habitat of this species; noun.
Diagnosis. This species resembles P. narathiwat Huber, 2016 (see Huber et al. 2016c: 33, figs 106–107, 124– 128, 137–139) with similar male chelicerae (Fig. 18 D) and female genitalia (Figs 18 A–B) but can be distinguished by the larger sclerite on the procursus distally (arrow in Fig. 17 C), by the S-shaped uncus (Fig. 18 C) and by the appendix not bifid (Fig. 18 C).
Description. Male (holotype): Total length 3.99 (4.23 with clypeus), carapace 0.95 long, 1.04 wide, opisthosoma 3.04 long, 0.75 wide. Leg I: 32.89 (7.82 + 0.44 + 7.95 + 14.49 + 2.19), leg III: 17.00 (5.13 + 0.38 + 4.04 + 6.54 + 0.91), legs II and IV missing; tibia I L/d: 72. Distance PME-PME 0.36; diameter PME 0.10; distance PME-ALE 0.03; AME absent. Thoracic furrow absent. Sternum wider than long (0.65/0.60). Habitus as in Figs 18 E–F. Carapace whitish, with darker V-pattern; ocular area yellowish; sternum whitish. Legs yellowish, patellae, distal parts of femora and proximal parts of metatarsi dark brown; darker rings absent. Opisthosoma whitish, without spots. Ocular area elevated, each eye triad on top of a long, laterally directed eye-stalk. Thoracic furrow absent. Chelicerae as in Fig. 18 D, with a pair of distal apophyses (without modified setae), a pair of frontal apophyses. Pedipalps as in Figs 17 A–B; trochanter with a short ventral apophysis (arrow 1 in Fig. 17 B); femur with a small retrolatero-dorsal apophysis proximally (arrow 2 in Fig. 17 B); procursus simple proximally but complex distally, with a long, curved ventral apophysis, and a large sclerite distally (arrow in Fig. 17 C); bulbal apophyses as in Fig. 18 C; uncus with scales; appendix strongly curved; embolus short, weakly sclerotized, with some transparent projections distally. Retrolateral trichobothrium of tibia I at 3%; legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae; tarsus I with 24 distinct pseudosegments.
Female: Similar to male, habitus as in Figs 18 G–H. Total length 5.05 (5.36 with clypeus), carapace 1.25 long, 1.31 wide, opisthosoma 3.80 long, 1.69 wide; tibia I: 10.90; tibia I L/d: 91. Distance PME-PME 0.25; diameter PME 0.08; distance PME-ALE 0.03; AME absent. Sternum wider than long (0.83/0.78). Ocular area without eyestalks. Epigynum (Fig. 18 A) with a small and posterior knob. Vulva (Fig. 18 B) with a sclerotized anterior arch and two rounded pore plates.
Variation: Unknown (leg I lost in the other specimens).
