Pimoa gyirong Zhang & Li sp. nov. Figures 15, 16, 55, 59

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) (vs. wider) and distinguished from P. rongxar by the broad cymbial denticulate process, with many cuspules distally (Figs 15B, 55A) (vs. distally narrow, with few cuspules) and the shorter pimoid cymbial sclerite (Fig. 55A) (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) (vs. pointed) and distinguished from P. reniformis by the spermathecae separated by ca. 1/4 the width of a spermatheca (Fig. 16A) (vs. unseparated).
