Pimoa heishui Zhang & Li sp. nov. Figures 17, 18, 55, 59

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, 55C) and P. yele sp. nov. (Figs 49A, B, 58A) but can be distinguished by the distally broad pimoid embolic process with spines (Fig. 55B) (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) (vs. without a spine) and by the short and wide cymbial denticulate process (Fig. 55B) (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) (vs. without a distal tip in P. lihengae and P. wanglangensis) and also distinguished from P. wanglangensis by the unseparated spermathecae (Fig. 18A) (vs. spermathecae with small separation).
