Figs 4–5
Differential diagnosis
The new species resembles Y. pulchella sp. nov., but can be distinguished by: (1) embolus much longer than the palpal bulbus, originating from the position of 7:00 o’clock (Figs 4B, 5A) vs as long as palpal bulbus, and originating from the position of 9:00 o’clock in Y. pulchella sp. nov. (Figs 1B, 2A) in ventral view, (2) palpal bulbus slightly wider anteriorly, depressed posteriorly (Figs 4B, 5A) vs much wider anteriorly and bulging posteriorly in Y. pulchella sp. nov. (Figs 1B, 2A) in ventral view, (3) the visible portion of the sperm duct originates from the posterior portion of the palpal bulbus (Figs 4B, 5A) vs from the anterior portion of the palpal bulbus in Y. pulchella sp. nov. (Figs 1B, 2A) in ventral view, (4) epigynal pockets bell-shaped, longer than wide, and separated from each other for more than four times of epigynal pocket width (Figs 4E, 5C) vs as long as wide, and almost touching each other in Y. pulchella sp. nov. (Figs 1E, 2C), (5) copulatory opening “()”-shaped and longitudinal (Figs 4E, 5C) vs slit-shaped and diagonal in Y. pulchella sp. nov. (Figs 1E, 2C), and (6) the course of the copulatory ducts is also different (Figs 4F, 5D).
Etymology
The specific name comes from the type locality.

Description
Male (holotype)
Total length 6.98 mm. Cephalothorax 3.28 × 2.44 mm. Abdomen 3.49 × 2.03 mm. Eye sizes and interdistances: AME 0.63 mm, ALE 0.34 mm, PLE 0.18 mm. AER 2.06 mm, PER 1.82 mm, EFL 1.38 mm. Carapace reddish brown, with three longitudinal yellowish-brown stripes on the median and two on the lateral areas (extending from the posterior margin of the ocular area to posterior margin of carapace). Lateral areas densely covered with longitudinal white hairs strips. Central area lightly colored. The base of each eye, anterior and lateral margins of ocular area black with black hairs. Thoracic region flat, fovea longitudinal, shallow, and indistinct. Cervical and radial grooves distinct. Sternum oval, covered with short brown hairs, central area bulged. Chelicerae yellowish-brown, two pro-marginal and one retro-marginal tooth. Legs yellowish-brown with annuli, terminal area darker. Measurements of legs: I 7.35 mm (2.52 mm, 2.82 mm, 1.28 mm, 0.73 mm), II 5.87 mm (2.04 mm, 2.43 mm, 0.89 mm, 0.51 mm), III 6.03 mm (2.26 mm, 2.32 mm, 0.85 mm, 0.60 mm), IV 6.96 mm (2.30 mm, 2.42 mm, 1.54 mm, 0.70 mm). Leg formula: 1432. Abdomen oval, dark brown with lighter yellowish central area with inclined white stripes, followed by the longitudinal dark band on lateral areas and transversally in the posterior, dorsum scattered with lots of white and grayish-black patches, lateral area two pairs of muscular impressions distinct. Venter white, scattered with black patches, median area with one longitudinal dark brown stripe. Palp (Figs 4 B–C, 5A–B): tibia thick, terminal part of the tibial apophysis straight in retrolateral view. Palpal bulbus slightly wider anteriorly, with a membranous structure at the center, posterior end with a deep depression. Embolus bow-shaped, much longer than the palpal bulbus, originated from the position of 7:00 o’clock. Sperm ducts robust. Variation: total length 5.97–6.98 mm (n = 10).
Female

AER 1.82 mm, PER 1.67 mm, EFL 1.19 mm. Carapace the same as male except dark colored. Carapace yellowishbrown. Legs light yellow, terminal areas darker with annuli in III and IV. I and II darker than III and IV. Measurements of legs: I 4.52 mm (1.42 mm, 1.87 mm, 0.69 mm, 0.54 mm), II 4.05 mm (1.51 mm, 1.59 mm, 0.58 mm, 0.37 mm), III 4.27 mm (1.61 mm, 1.25 mm, 0.97 mm, 0.44 mm), IV 4.85 mm (1.66 mm, 1.81 mm, 0.98 mm, 0.40 mm).
