Type material.
Holotype: ♂ (IZCAS-Ar41945), China, Tibet, Nyingchi, Gongbo’gyamda County, Gyara Village, 30.01°N, 93.78°E, ca. 3460 m, 14.VII.2019, X. Zhang, Z. Bai and J. Liu leg. Paratypes: 1♂2♀ (IZCAS-Ar41946-Ar41948), same data as holotype.
Etymology.
The specific name is a noun in apposition taken from the type locality.
Diagnosis.
The male of Pimoa gyara sp. nov. resembles those of P. nyingchi (see Zhang et al. 2020: 91, fig. 8A-C) and P. reniformis (see Xu and Li 2007: 493, figs 36-41) but can be distinguished from P. nyingchi by the narrow and distally curved cymbial denticulate process (Fig. 54D View Figure 54 ) (vs. flat distally and wide) and from P. reniformis by the U-shaped pimoid cymbial sclerite (Fig. 54D View Figure 54 ) (vs. triangular). The female of P. gyara sp. nov. also resembles P. nyingchi (see Zhang et al. 2020: 91, fig. 9A-D) but can be distinguished by the distally blunt dorsal plate (Fig. 14B View Figure 14 ) (vs. pointed) and by the spermathecae separated by ca. 1/2 width of spermatheca (Fig. 14A View Figure 14 ) (vs. close to each other).

Leg measurements: I: 25.04 (6.88, 8.22, 7.13, 2.81); II: 21.63 (6.03, 7.16, 6.03, 2.41); III: 15.38 (4.72, 4.91, 4.34, 1.41); IV: 19.62 (5.66, 6.47, 5.65, 1.84). Habitus as in Fig. 14E View Figure 14 . Carapace yellowish with black lateral margins; thoracic fovea and radial grooves distinct; sternum brownish. Abdomen black with yellow transverse chevrons, nearly oval. Legs brownish without annulations. Palp (Figs 13A, B View Figure 13 , 54D View Figure 54 ): patella short, almost as long as tibial length, with one retrolateral macroseta; tibia short, ca. 1/3 of cymbial length, with several macrosetae and a dorsal process; paracymbium short, ca. 1/4 of cymbial length, finger-shaped; pimoid cymbial sclerite U-shaped, ca. 1/2 of cymbial length; cymbial denticulate process short, distally narrow and curved, with more than 20 cuspules; median apophysis slender; conductor distinct; pimoid embolic process distally pointed, length subequal to embolus; embolus beginning at the 3:00 o’clock position; embolic tooth absent.
Female (paratype): Total length 7.40. Carapace 3.44 long, 2.97 wide. Abdomen 3.96 long, 2.59 wide. Eye sizes and interdistances: AME 0.22, ALE 0.23, PME 0.16, PLE 0.22; AME-AME 0.09, AME-ALE 0.16, PME-PME 0.15, PME-PLE 0.24. Leg measurements: I: 19.60 (5.47, 6.78, 5.13, 2.22); II: 16.89 (4.94, 5.75, 4.39, 1.81); III: 12.04 (3.84, 4.16, 3.01, 1.03); IV: 16.82 (5.09, 5.69, 4.38, 1.66). Habitus as in Fig. 14F, G View Figure 14 . Carapace yellowish with black lateral margins; thoracic fovea and radial grooves distinct; sternum brownish. Abdomen black with yellowish transverse bands. Legs brownish without annulations. Epigyne (Fig. 14A-D View Figure 14 ): triangular; ventral plate broad, width subequal to length; dorsal plate tongue-shaped, shorter than ventral plate; copulatory openings indistinct; spermathecae oval, separated by ca. 1/3 width of spermatheca; fertilization ducts yellowish, anteriorly oriented.
