Type material.
Holotype: ♂ (IZCAS-Ar41953), China, Sichuan, Heishui County, Deshiwo Village, the cave in the first grade power station, 32.03°N, 102.95°E, ca. 2429 m, 18.XI.2019, Z. Chen leg. Paratypes: 1♂2♀ (IZCAS-Ar41954-Ar41956), same data as holotype.
Etymology.
The specific name is a noun in apposition taken from the type locality.
Diagnosis.
The male of Pimoa heishui sp. nov. resembles those of P. jinchuan sp. nov. (Figs 19A, B View Figure 19 , 55C View Figure 55 ) and P. yele sp. nov. (Figs 49A, B View Figure 49 , 58A View Figure 58 ) but can be distinguished by the distally broad pimoid embolic process with spines (Fig. 55B View Figure 55 ) (vs. distally with scales and a short, slender spine subdistally in P. jinchuan sp. nov. and broad, robust, distally bifurcate apex with scales in P. yele sp. nov.) and also from P. jinchuan sp. nov. by the embolus with a short, slender spine proximally (Fig. 55B View Figure 55 ) (vs. without a spine) and by the short and wide cymbial denticulate process (Fig. 55B View Figure 55 ) (vs. distally long and narrow). The female of P. heishui sp. nov. resembles those of P. lihengae (see Griswold et al. 1999: 91-97, figs 18-21) and P. wanglangensis (see Yuan et al. 2019: 27, fig. 22G, H) but can be distinguished by the dorsal plate with a distally blunt tip (Fig. 18B View Figure 18 ) (vs. without a distal tip in P. lihengae and P. wanglangensis ) and also distinguished from P. wanglangensis by the unseparated spermathecae (Fig. 18A View Figure 18 ) (vs. spermathecae with small separation).
