Type material. CHINA, Sichuan Province: Holotype female from Aba Tibetan and Qiang Autonomous Prefecture , Wenchuan County, Wolong Town , Wolong National Nature Protection Panda Valley Scenic Spot, 30.97°N, 103.12°E, 2107 m, 8 May 2016 , Y. Zhong & Y. Zhu leg. ( CBEE, LJ2149 ).

Etymology. The specific name is derived from the type locality, the Wenchuan County; adjective.

Diagnosis. The female of P. wenchuanensis Zhang, Jäger & Liu , spec. nov. is similar to those of P. alta , P. fabularis , P. gibberosa and P. semiannulata by the median field of epigyne shaped as an inverted rounded trapezoid with anterior rims of the LL distinctly curved.

It can be recognised by the IDS with distinct loops freely visible in dorsal view and the reticulated parts of the IDS (sclerotised part of IDS covered by FW and LL in dorsal view, IDS with entire surface in P. alta , P. fabularis , P. gibberosa and P. semiannulata ).

FEMALE (LJ2149): Measurements: Medium sized. Body length 12.1, DS length 4.7, width 4.3, OS length 7.4, width 6.2. Eyes: AME 0.15, ALE 0.27, PME 0.21, PLE 0.24, AME–AME 0.13, AME–ALE 0.06, PME– PME 0.17, PME–PLE 0.25, AME–PME 0.22, ALE–PLE 0.20, CH AME 0.26, CH ALE 0.17. Spination: Pp 131, 101, 2121, 1014; Fe I–III 323, IV 331; Pa I–IV 100; Ti I–II 2228, III–IV 2126; Mt I–II 2024, III 2026, IV 3036. Measurements of palps and legs: Pp 6.4 (1.9, 0.8, 1.3, –, 2.4); I 17.1 (4.9, 1.6, 5.3, 4.2, 1.1); II 20.5 (5.7, 1.9, 6.0, 5.3, 1.6); III 13.9 (4.6, 1.2, 3.8, 3.5, 0.8); IV 16.1 (5.1, 0.7, 4.3, 4.7, 1.3). Leg formula: II-I-IV-III. Cheliceral furrow with ca. 23 denticles.

Epigyne ( Figs 257A–C ): As in diagnosis. EF wider than long, AB short and indistinct. IDS with two bubblelike structures at the middle part, with grid structure in the anterior part. Median part of anterior margins of LL covered by median field of epigyne. IDS clearly visible in dorsal view, not covered by LL in their posterior part.

Colouration ( Figs 258A–B ): DS yellow with dark spots and lines, the latter especially between eyes and fovea, margin with irregular black patterns. Fovea distinctly marked. OS dorsally brown with a dark region at the middle part in longitudinal axis, with a transverse procurved yellow line at posterior part, ventrally brown with lots of dark marks, irregularly arranged.

MALE: Unknown.

Distribution. China (Sichuan Province).
