Figs 1–4, 10

Type material. Holotype ♂: CHINA: Yunnan Province: Dali Bai Autonomous Prefecture, Fengyi Town (25°35′26.61″N, 100°18′8.57″E), 2026 m elev., 15.VII.2021, leg. Yannan Mu.

Paratypes: 10♂ 33♀, same data as holotype .

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

Diagnosis. This new species can be distinguished from P. baoshanensis sp. n. by 1) RTA wider than in the latter species, and the distance between the RTA and cymbium smaller than P. baoshanensis sp. n.; 2) bursa triangular and positioned above the spermathecae, and separated by about half the diameter of spermathecae (vs close in P. baoshanensis sp. n.); 3) spermathecae large and round as opposed to small and oval in P. baoshanensis sp. n..

Carapace oval, dark in color, with several slight lighter bands either side of fovea ( Figs 1A, 2A); middle of carapace with sparse iridescent scales, margin of carapace with ring of iridescent scales ( Fig. 2C). Sternum gray, without pattern. Abdomen darker than carapace, large dorsal scutum covering most of dorsum, with iridescent scales on side and behind dorsal scutum ( Fig. 2B). All femora and patella black, tibiae I–IV black with white tip except tibia III yellow, all metatarsi and tarsi yellowish without markings ( Fig. 3).

Palp as in Figs 4A–D. Femur without apophysis, swollen ventrally at middle parts, without setae. Patella and tibia short, cymbium longer than femur. Tibia with single large retrolateral apophysis and small dorsal apophysis. Tegulum narrower than cymbium, sperm duct two times longer than tegulum and half as wide as tegulum, curved as S-shaped in prolateral view. Embolus short, directed retrodistally. Conductor membranous, triangular.

Female: One paratype: total length 2.34, carapace 1.05 long, 0.83 wide; abdomen 1.29 long, 0.83 wide. Eye sizes and interdistances: AME 0.06, ALE 0.08, PME 0.06, PLE 0.06; AME – AME 0.04, AME – ALE 0.01, ALE – ALE 0.17, PME – PME 0.05, PME – PLE 0.03, PLE – PLE 0.23, ALE – PLE 0.05.

Other characters as for male, except larger body size, broad band with dense iridescent scales posterior to eye area, and without dorsal scutum on abdomen ( Fig. 2E–F) .

Epigyne as in Fig. 4E–H. Copulatory openings large, situated medially, separated by about 2.5 times spermathecae diameter. Copulatory ducts short, thick. Bursa triangular, semi-transparent. Connecting tube between bursae and spermathecae thinner than copulatory ducts. Spermathecae round, separated by more than half their width. Fertilization ducts located on dorsal side of spermathecae.
