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 View FIGURE 18 D) and female genitalia ( Figs 18 View FIGURE 18 A–B) but can be distinguished by the larger sclerite on the procursus distally (arrow in Fig. 17 View FIGURE 17 C), by the S-shaped uncus ( Fig. 18 View FIGURE 18 C) and by the appendix not bifid ( Fig. 18 View FIGURE 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 View FIGURE 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 View FIGURE 18 D, with a pair of distal apophyses (without modified setae), a pair of frontal apophyses. Pedipalps as in Figs 17 View FIGURE 17 A–B; trochanter with a short ventral apophysis (arrow 1 in Fig. 17 View FIGURE 17 B); femur with a small retrolatero-dorsal apophysis proximally (arrow 2 in Fig. 17 View FIGURE 17 B); procursus simple proximally but complex distally, with a long, curved ventral apophysis, and a large sclerite distally (arrow in Fig. 17 View FIGURE 17 C); bulbal apophyses as in Fig. 18 View FIGURE 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 View FIGURE 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 View FIGURE 18 A) with a small and posterior knob. Vulva ( Fig. 18 View FIGURE 18 B) with a sclerotized anterior arch and two rounded pore plates.

Variation: Unknown (leg I lost in the other specimens).

Distribution. Indonesia (Central Kalimantan, type locality; Fig. 21 View FIGURE 21 ).
