Etymology. The specific name refers to its similarity to P. thompsoni Alderweireldt & Jocqué, 1992 ; adjective.

Diagnosis. Male palp of the new species is very similar to P. thompsoni ( Alderweireldt & Jocqué 1992: 102, figs 31–32), but can be distinguished by the different shape of palea and the relatively stout median apophysis ( Figs 1 A–C, 2D–H). Epigyne ( Figs 1 D–E, 2I –J) can be distinguished by the short and narrow stem of septum. The new species is also similar to another Chinese species, P. c h ap i n i ( Fox, 1935) ( Figs 8 A–H, 9A–D, male and female specimens from Sichuan and Guizhou, China), but differs by the yellow body, the rectangular, slightly curved median apophysis, the short stem septum, the small hoods and the different location of fertilisation ducts.

Description. Male total length 5.43–8.24. Holotype ( Figs 2 A, 2C) total length 8.24. Prosoma 4.36 long, 3.43 wide; opisthosoma 4.00 long, 2.30 wide. Carapace dark brown, with light brown submarginal bands. Median band brownish yellow, dilated in cephalic area. Lateral bands dark brown and broad. Eye region black. Flanks of the head region vertical in frontal view. Cervical groove and radial furrows indistinct. Eye sizes and interdistances: AME 0.18, ALE 0.15, PME 0.44, PLE 0.39; AME–AME 0.14, AME–ALE 0.06, PME–PME 0.43, PME–PLE 0.45. Clypeus height 0.32. Chelicerae elongate, black brown, with two promarginal and three retromarginal teeth.

Labium grey and length equals to its width. Endites grey, longer than wide. Sternum dark, heart-shaped, with sparse black hairs. Legs yellow, with black ring-like stripe. Leg measurements: I 12.79 (3.65, 4.25, 2.87, 2.02); II 12.45 (3.35, 4.16, 3.06, 1.88); III 12.40 (3.27, 4.03, 3.19, 1.91); IV 17.17 (4.40, 5.27, 5.33, 2.17). Leg formula: 4123. Opisthosoma long oval. Dorsum dark brown, with willow leaf-shaped cardiac marking and a couple of yellow spots in anterior half. Venter of opisthosoma yellow, with small, yellow spinnerets posteriorly.

Male palp ( Figs 1 A–C, 2D–H) with a large tegulum. Subtegulum small, located prolaterally. Median apophysis rectangular, with a somewhat ventrally curved end. Large palea located in the distal part of male bulb. Embolus prolaterally originated, extending ventro-retrolaterally. Terminal apophysis beak-like.

Female paratype ( Fig. 2 B) (from Nongdao Town) total length 5.02. Prosoma 2.08 long, 1.64 wide; opisthosoma 2.63 long, 1.72 wide. Eye sizes and interdistances: AME 0.57, ALE 0.42, PME 1.42, PLE 0.82; AME–AME 0.38, AME–ALE 0.22, PME–PME 1.16, PME–PLE 0.98. Clypeus height 0.67. Leg measurements: I 6.20 (1.79, 2.03, 1.36, 1.02); II 5.87 (1.69, 1.83, 1.42, 0.93); III 5.85 (1.70, 1.75, 1.54, 0.86); IV 9.06 (2.40, 2.70, 2.80, 1.16). Leg formula: 4123. Colouration and pattern similar to that of male, but opisthosoma relatively darker than that of male.

Epigyne ( Figs 1 D–E, 2I –J) with an anchor-like septum and a pair of small apical hoods. Septum shorter than wide, with a short and narrow stem and the base wider than long. A pair of spermathecae large, slightly longer than wide. Fertilisation ducts short, originated from the inner side of the posterior margin of spermathecae.

Distribution. China (Yunnan) ( Fig. 10 ).
