Figures 1–13 , 23

Etymology. The specific name is from the Latin word candidus (bright), adjective, and refers to the bright coloration of live specimens.

Diagnosis. The male of the new species closely resembles P. submontanus Prószyński, 1992 ( Prószyński 1992: figs 116–117) known from West Bengal, India and P. wangdicus Żabka, 1990 ( Żabka 1990: figs 16–18) from Bhutan in the palpal structure, but can be distinguished by the obtuse tip of the RTA in retrolateral view ( Fig 7 ), which is pointed in P. submontanus and P. wangdicus . The female somewhat resembles P. goulufengensis Peng, Yin, Yan & Kim, 1988 (Peng et al. 1988: figs 4–6) from Hunan, China in having a paired pocket, but differs in: 1) the copulatory ducts are anterior-lateral to receptacles vs posterior to receptacles in P. goulufengensis ; 2) the copulatory openings are located anteriolaterally vs posteriolaterally in P. goulufengensis ; and 3) the receptacle is almost round vs oval in P. goulufengensis .( Figs 8–9 ).

Description. Male (Holotype, SCAU-YN-20190216001). Total length 6.34, PL 3.41, PW 2.82, OL 2.93, OW 1.93. Eye sizes: AME 0.71, ALE 0.39, PME 0.09, PLE 0.42; AER 2.57, PER 2.38, EFL 1.69. Clypeus height 0.37. Legs: I 8.14 (2.24, 0.97, 2.43, 1.55, 0.95); II 6.78 (2.15, 0.90, 1.71, 1.19, 0.83); III 7.91 (2.72, 0.99, 1.64, 1.68, 0.88); IV 7.55 (2.24, 0.74, 1.76, 2.02, 0.79).

Leg formula: 1342. Prosoma greyish-yellow, covered by white setae running from AMEs to PLEs, shaped into anteriorly prolonged hexagon, densely covered with black setae around eye field. Vibrant red-brown setae around AER. Lateral sides of prosoma with U-shaped zone of white setae, centrally disconnected. Chelicerae dark brown, with two promarginal and one retromarginal teeth. Clypeus dark-brown, with pale inner tip. Maxillae and labium dark-brown, with black setae. Sternum elliptical, light greyish-yellow. Opisthosoma suboval, light greyish-yellow. Dorsum scattered with quantities of black bristles, central area covered with white setae, forming longitudinal irregular stripe, narrowed medially. Venter dark-grey medially and pale bilaterally, with four longitudinal dotted lines. Spinnerets dark-grey, densely covered with setae. Legs dark-brown and greyish-yellow, significantly contrasting, each leg with spines, leg I with dense dark setae.

Palp: tibia approximately 1/2 cymbial length. RTA short, rectangular, terminus flat, tip slightly extended towards dorsum; tegulum with marked elongated lobe. Embolus arising disto-prolaterally on tegulum, stout basally, with pointed tip almost directed towards 1 o’clock in ventral view.

Female (Paratype, SCAU-YN-20190216002). Total length 6.30, PL 3.36 , PW 2.68 , OL 2.94, OW 1.98. Eye sizes: AME 0.76, ALE 0.41, PME 0.14, PLE 0.37; AER 2.43, PER 2.19, EFL 1.50. Clypeus height 0.18. Legs: I 6.48 (1.94, 0.92, 1.76, 1.09, 0.77); II 5.97 (1.92, 0.88, 1.49, 0.95, 0.73); III 7.41 (2.54, 0.92, 1.58, 1.47, 0.90); IV 7.46 (2.34, 0.79, 1.74, 1.73, 0.86) .

Habitus similar to that of male except dorsum of opisthosoma darker, lacking distinct prolonged hexagon marking of white setae on prosoma, and red-brown setae around AER.

Epigyne: epigynal plate anteriorly extended, sector-shaped. Copulatory openings laterally widened, slit-shaped. Copulatory ducts thick, running posteriorly. Paired bell-shaped epigynal pockets situated posteriorly, separated from each other by less the 1/2 their width. Receptacles circular, immediately adjacent to each other. Fertilization ducts originate from anterior edge of receptacles.

Type material. Holotype ³: CHINA: Yunnan: Yingjiang County, Nabang Town, Rongshuwang Scenic Spot , 24°40’04.22’’N, 97°35’57.66’’E, 937 m a.s.l., leg. Wei-hang Wang, 16.II.2019 (beating shrubs) (SCAU-YN- 20190216001). The type material was captured in subadult stage, raised in the lab and all specimens matured at 4.IV.2019.

Paratypes: Same data as holotype, 2♀ (SCAU-YN-20190216002, SCAU-YN-20190216003) .

Habitat. Specimens of the new species were collected from the foliage of shrubs in a mountain area, and the species has not been recorded in plain terrain yet.

Distribution. Known only from the type locality in Yunnan, China.
