Figures 8 , 9 , 16 Type material. Holotype : ♂ (IZCAS-Ar40323), China, Tibet, Nyingchi, near Lunang Town, 29.94°N , 94.80°E , elevation ca. 2615 m, 25.VIII.2018, X. Zhang and J. Liu leg. Paratypes : 1♂2♀ (IZCAS-Ar40324-Ar40326), same data as holotype; 2♂2♀ (IZCAS-Ar40327-Ar40330), Nyingchi, Near Sejila Pass, 29.56°N , 94.57°E , elevation ca. 3764 m, 26.VIII.2018, X. Zhang and J. Liu leg. Etymology. The specific name is a noun in apposition taken from the type locality. Diagnosis. The male of Pimoa nyingchi sp. nov. resembles P. reniformis (see Xu and Li 2007 : 493, figs 36-41) but can be distinguished by the long, distally flat and wide pimoid cymbial sclerite (Fig. 8B , vs. narrow and distally curved) and by the relatively large and wide paracymbium (Fig. 8B, C , vs. small and narrow). The female of P. nyingchi also resembles P. reniformis (see Xu and Li 2007 : 493, figs 42-47) but can be distinguished by a pair of small, oval spermathecae (Fig. 9C , vs. large and kidney-shaped) and by the broad dorsal plate (Fig. 9C , vs. narrow dorsal plate).

Distribution. Known only from the type locality, Tibet, China (Fig. 16 ).
