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).

Distribution. Known only from the type locality, Gansu, China (Fig. 59 ).
