Pimoa xiahe Zhang & Li sp. nov. Figures 46, 47, 57, 59
Type material.
Holotype: ♂ (IZCAS-Ar42006), China, Gansu, Gannan Tibetan Autonomous Prefecture, Xiahe County, Damai Township, Xiongmao Valley, 35.16°N, 102.67°E, ca. 3046 m, 10.VII.2020, Y. Lin and Z. Wang leg. Paratypes: 1♂2♀ (IZCAS-Ar42007-Ar42009), same data as holotype.
Etymology.
The specific name is a noun in apposition taken from the type locality.
Diagnosis.
The male of Pimoa xiahe sp. nov. resembles those of P. samyai (see Zhang et al. 2020: 97, fig. 12) and P. crispa (see Hormiga 1994a: 63, figs 233-238; Hormiga 1994b: fig. 1A, B) but can be distinguished by the short cymbial denticulate process with few cuspules (Figs 46B, 57D) (vs. large, with many cuspules) and a proximal apophysis of the pimoid embolic process (Fig. 57D) (vs. without apophysis). The female of P. xiahe 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 by the medially wide dorsal plate (Fig. 47B) (vs. medially narrow).
