Phrurotimpus baoshanensis sp. n. (保山提ůfl)

Figs 5–8

Type material. Holotype ♂: CHINA: Yunnan Province: Baoshan City, Longyang District, Taibao Park (25°07′26.83″N, 99°08′49.28″E), 1849 m elev., 20.VII.2021, leg. Yannan Mu.

Paratypes: 7♂ 19♀, same data as holotype .

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

Diagnosis. This new species is similar to P. lasiolepis comb. n., but can be distinguished by: 1) the thinner and curved conductor; 2) the larger RTA, and the position of the base of the RTA, which extends to the cymbium with a broad gap; 3) the bursa close to each other and more strongly curved, forming a J-shape.

Description. Male (Holotype): total length 2.06, carapace 0.97 long, 0.78 wide; abdomen 1.09 long, 0.61 wide. Eye sizes and interdistances: AME 0.06, ALE 0.08, PME 0.05, PLE 0.06; AME–AME 0.03, AME–ALE 0.01, ALE–ALE 0.15, PME–PME 0.05, PME–PLE 0.04, PLE–PLE 0.22, ALE–PLE 0.05. EAW 0.30, CRW 0.38, EAW/ CRW 0.79, CRW/CW 0.49. MOA 0.15 long, anterior width 0.15, posterior width 0.14. CH 0.09, CH /AME 1.50. Labium 0.10 long, 0.14 wide. Sternum 0.62 long, 0.47 wide. Carapace oval, brown in color, with several slightly lighter bands either side of fovea ( Fig. 5A , 6A ); middle of carapace with sparse iridescent scales, margin of carapace with ring of iridescent scales ( Fig. 6C ). Sternum mottled gray, without pattern ( Fig. 5B ). Abdomen black, large dorsal scutum covering most of dorsum, with iridescent scales on side and behind dorsal scutum ( Fig. 6B ). Femora and patella I–II black, femora and patella III–IV yellow, tibiae I–IV black with white tip except tibia III yellow, all metatarsi and tarsi yellowish without markings, except metatarsus IV black with yellow tip ( Fig. 7 ).

Palp as in Figs 8A–D . Femur without apophysis, with asetose swolling ventrally at the middle. Patella and tibia short, cymbium longer than femur. Tibia with single large retrolateral apophysis and small dorsal apophysis; gap to cymbium wider than in P. daliensis sp. nov.. Bulb narrower than cymbium, distinct sperm duct tapering from retrolateral side to prolateral side, S-shaped in prolateral view. Embolus short, spike-shaped. Conductor membranous, triangular.

Female (one paratype): total length 2.85, carapace 1.14 long, 0.95 wide; abdomen 1.71 long, 1.12 wide. Eye sizes and interdistances: AME 0.08, ALE 0.08, PME 0.06, PLE 0.07; AME – AME 0.04, AME – ALE 0.01, ALE – ALE 0.18, PME – PME 0.05, PME – PLE 0.04, PLE – PLE 0.25, ALE – PLE 0.05. EAW 0.35, CRW 0.47, EAW / CRW 0.74, CRW / CW 0.49. MOA 0.18 long, anterior width 0.18, posterior width 0.16. CH 0.09, CH / AME 1.13 . Labium 0.10 long, 0.19 wide. Sternum 0.77 long, 0.62 wide. Other characters as for male, except larger body size, broad band with more iridescent scales behind of eye area than male and without dorsal scutum on abdomen ( Figs 5C–D , 6D–F ) .

Epigyne as in Figs 8E–H . Copulatory openings large, situated medially, separated by about 3 times broader than spermathecae diameter. Copulatory ducts short and thick. Bursa J-shaped. Connecting tubes thinner than CDs. Spermathecae small, oval. Fertilization ducts located at anterior margin of spermathecae.
