Type material. CHINA, Hubei Province: Holotype male from Xianning City, Tongshan County, Jiugongshan Scenic Spot , 29.40°N, 114.66°E, 1250 m, 17 June 2020, J. Liu & Z. Deng leg. ( CBEE, LJ20200614 ) . Paratypes: 6 males, 7 females, with same data as for holotype ( CBEE, LJ20200601 – LJ20200613 ) .

Etymology. The specific name is derived from the type locality, the Jiugongshan Scenic Spot; adjective.

Diagnosis. The male of P. jiugongensis Zhang, Jäger & Liu , spec. nov. is similar to that of P. lushanensis by: 1) Long filiform E with broad base; 2) RTA similar simple finger-shaped without additional apophysis in ventral view. It can distinguish by the following combination of characters: RTA arising medially from Ti (RTA arising subdistally from Ti in P. lushanensis ). The female of P. jiugongensis Zhang, Jäger & Liu , spec. nov. is similar to that of P. lushanensis by: 1) 2 U-shaped anterior margins of LL; 2) IDS reaching far into anterior half of epigyne, but can be recognised by IDS almost forming a circular in dorsal view (IDS almost strip shape in dorsal view in P. lushanensis ).

MALE (LJ20200614): Measurements: Small sized. Body length 9.3–9.8, DS length 4.1, width 3.8, OS length 5.7, width 4.5.

Measurements of palps and legs: Pp 5.6 (1.5, 0.8, 1.2, –, 2.1); I 11.3 (3.4, 1.2, 3.2, 2.4, 1.1); II 15.0 (3.8, 1.7, 4.7, 3.5, 1.3); III 10.0 (3.2, 1.1, 2.7, 2.1, 0.9); IV 12.0 (3.6, 1.0, 2.9, 3.3, 1.2). Leg formula: IIIV-I-III. Cheliceral furrow with ca. 19 denticles.

Palp ( Figs 132A–C ): As in diagnosis. C arising from T at 11:30 o’clock position. E arising from T at 10:00– 11:00 o’clock position, basally broad, distinctly bent at its distal part, with long and filiform apical tip. Spermophor running submarginally dorsally to proximally along T. RTA simple, arising medially from Ti, with blunt tip in ventral view.

Colouration ( Figs 134A–B ): DS yellow with dark marks. Fovea and striae distinct. OS dorsally yellow with brown patches regularly arranged, ventrally yellowishbrown with several dots and a narrow transverse band in the posterior half.

FEMALE (LJ20200607): Measurements: Small sized. Body length 7.1–7.8, DS length 3.8, width 3.4, OS length 3.5, width 2.3. Eyes: AME 0.17, ALE 0.24, PME 0.19, PLE 0.21, AME–AME 0.16, AME–ALE 0.10, PME–PME 0.19, PME–PLE 0.33, AME–PME 0.29, ALE–PLE 0.26, CH AME 0.37, CH ALE 0.30. Spination: Pp 131, 101, 2121, 1014; Fe I–II 323, III 322, IV 331; Pa I–III 101, IV 000; Ti I–II 2228, III–IV 2126; Mt I–II 3034, III–IV 3036. Measurements of palps and legs: Pp 6.1 (1.8, 0.7, 1.1, –, 2.5); I 14.7 (4.5, 1.4, 4.2, 3.6, 1.0); II 19.2 (5.2, 1.8, 5.9, 4.7, 1.6); III 12.6 (3.8, 1.2, 3.6, 3.3, 0.7); IV 15.4 (4.7, 0.9, 4.0, 4.4, 1.4). Leg formula: II-IV-I-III. Cheliceral furrow with ca. 25 denticles.

Epigyne ( Figs 133A–C ): As in diagnosis. EF wider than long, trilobate, with poorly developed AB. Anterior margins of LL deeply concave, leading medially behind a transversal rim. IDS longer in longitudinal axis. FD situated behind the IDS in dorsal view.

Colouration ( Figs 134C–D ): As in male, generally darker. The white transversal patch at the posterior half of dorsal OS.

Distribution. China (Hubei Province).
