Figures 5A, B, 6A–D, 7D, 8

Type material. Holotype: male, China, Qinghai, Zekog County, Maixiu Forest Farm, 35°18′32″ N, 101°56′31″ E, elev. 2875 m, 26 August 2019, L.Y. Wang and Z.J. Shi leg. (SWUC-T-PI-05-01).

Etymology. The specific name refers to the type locality.

Diagnosis. Pimoa zekogensis n. sp. resembles P. rongxar Zhang et al. 2020 (Zhang et al. 2020: 94, figs 10A–C, 11A–B) in having a similar embolus; conductor, median apophysis slender; and the pimoid embolic process distal end abruptly narrow (Figs 5A, B, 6A–C). It also resembles P. samyai Zhang et al. 2020 (Zhang et al., 2020: 97, figs 12A–C, 13A–G) in having a similar paracymbium (Fig. 6A–C). However, the new species can be distinguished from all other Pimoa species by the pimoid cymbial sclerite L-shaped, distal end thin with a blunt end and the distalend of the cymbial denticulate process spoon-shaped with roughly eight cuspules (Figs 5A, B, 6A–C).

Description. Male (holotype, Fig. 7D): Total length 8.09. Carapace 3.94 long, 2.72 wide. Abdomen 4.55 long, 2.57 wide. Eye sizes and interdistances: AME 0.17, ALE 0.20, PME 0.18, PLE 0.20; AME–AME 0.13, AME–ALE 0.13, PME–PME 0.16, PME–PLE 0.18. Carapace brownish with black lateral margins; thoracic fovea and radial grooves distinct; sternum brownish. Abdomen black with yellowish transverse chevron bands. Legs brownish with black annulations. Leg measurements: I: 32.86 (8.92, 10.97, 9.50, 3.47); II: 30.55 (8.40, 10.16, 8.77, 3.22); III: 19.11 (5.56, 6.05, 5.37, 2.13); IV: 25.98 (7.45, 8.51, 7.30, 2.63).

Palp (Figs 5A, B, 6A–D): tibia longer than wide, half of cymbial length, with several macrosetae and a dorsal process; paracymbium short, about one-fifth of cymbial length, slightly curved with a pointed tip; pimoid cymbial sclerite short, L-shaped in ventral view; cymbial denticulate process broad and short, with roughly eight cuspules; median apophysis slender, indistinct; conductor distinct; pimoid embolic process longer than embolus, distal margin abruptly narrowing; embolus beginning at the five-thirty o’clock position; embolic tooth absent.

Female. Unknown.

Distribution. Known only from the type locality, Qinghai, China (Fig. 8).
