Type material.
Holotype: ♂ (IZCAS-Ar41949), China, Tibet, Shigatse, Gyirong County, Gyirong Town, near Lhanggyi Tso Holy Lake, 28.41°N, 85.40°E, ca. 3909 m, 7.VII.2019, X. Zhang, Z. Bai and J. Liu leg. Paratypes: 1♂2♀ (IZCAS-Ar41950-Ar41952), same data as holotype.
Etymology.
The specific name is a noun in apposition taken from the type locality.
Diagnosis.
The male of Pimoa gyirong sp. nov. resembles those of P. crispa (see Hormiga 1994a: 63, figs 233-238; Hormiga 1994b: fig. 1A, B) and P. rongxar Zhang & Li, 2020 (see Zhang et al. 2020: 94, fig. 10A-C) but can be distinguished from P. crispa by the distally narrower cymbial denticulate process (Fig. 55A View Figure 55 ) (vs. wider) and distinguished from P. rongxar by the broad cymbial denticulate process, with many cuspules distally (Figs 15B View Figure 15 , 55A View Figure 55 ) (vs. distally narrow, with few cuspules) and the shorter pimoid cymbial sclerite (Fig. 55A View Figure 55 ) (vs. large and wide subdistally). The female of P. gyirong sp. nov. resembles those of P. nyingchi (see Zhang et al. 2020: 91, fig. 9A-D) and P. reniformis (see Xu and Li 2007: 493, figs 42-47) but can be distinguished from P. nyingchi by the distally blunt dorsal plate (Fig. 16B View Figure 16 ) (vs. pointed) and distinguished from P. reniformis by the spermathecae separated by ca. 1/4 the width of a spermatheca (Fig. 16A View Figure 16 ) (vs. unseparated).
