Pimoa nyalam Zhang & Li sp. nov. Figures 35 View Figure 35 , 36 View Figure 36 , 56 View Figure 56 , 59 View Figure 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 View Figure 15 , 55A View Figure 55 ) but can be distinguished by the short and distally narrowed cymbial denticulate process (Fig. 56D View Figure 56 ) (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 View Figure 56 ) (vs. shorter) and the smaller pimoid cymbial sclerite (Fig. 56D View Figure 56 ) (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 View Figure 36 ) (vs. distally narrow, with a tip) and from P. samyai by the trapezoidal dorsal plate (Fig. 36A View Figure 36 ) (vs. tongue shaped).
