Pimoa nyalam Zhang & Li sp. nov. Figures 35, 36, 56, 59

Type material.

Holotype: ♂ (IZCAS-Ar41986), China, Tibet, Shigatse, Nyalam County, Zham Town, near the dam, 28.09°N, 86.00°E, ca. 3326 m, 9.VII.2019, X. Zhang, Z. Bai and J. Liu leg. Paratypes: 1♂2♀ (IZCAS-Ar41987-Ar41989), same data as holotype.

Etymology.

The specific name is a noun in apposition taken from the type locality.

Diagnosis.

The male of Pimoa nyalam sp. nov. resembles those of P. crispa (see Hormiga 1994a: 63, figs 233-238; Hormiga 1994b: fig. 1A, B) and P. gyirong sp. nov. (see Figs 15A, B, 55A) but can be distinguished by the short and distally narrowed cymbial denticulate process (Fig. 56D) (vs. large and laterally broad in P. crispa and wide in P. gyirong sp. nov.) and also from P. gyirong sp. nov. by the longer palpal tibia (Fig. 56D) (vs. shorter) and the smaller pimoid cymbial sclerite (Fig. 56D) (vs. large). The female of P. nyalam sp. nov. also resembles those of P. crispa (see Hormiga 1994a: 63, figs 239-247) and P. samyai (see Zhang et al. 2020: 97, fig. 13A-D) but can be distinguished from P. crispa by the distally blunt dorsal plate (Fig. 36B) (vs. distally narrow, with a tip) and from P. samyai by the trapezoidal dorsal plate (Fig. 36A) (vs. tongue shaped).
