Pimoa jinchuan Zhang & Li sp. nov. Figures 19 View Figure 19 , 20 View Figure 20 , 55 View Figure 55 , 59 View Figure 59

Type material.

Holotype: ♂ (IZCAS-Ar41957), China, Sichuan, Jinchuan County, the bridge from Xilizhai Village to Xiaojin County, 31.34°N, 102.19°E, ca. 3411 m, 23.XI.2019, Z. Chen leg. Paratypes: 1♂1♀ (IZCAS-Ar41958-Ar41959), same data as holotype.

Etymology.

The specific name is a noun in apposition taken from the type locality.

Diagnosis.

The male of Pimoa jinchuan sp. nov. resembles those of P. lata (see Zhang and Li 2019: 6, fig. 3A-C), P. trifurcata Xu & Li, 2007 (see Xu and Li 2007: 496, figs 48-54) and P. yele sp. nov. (Figs 49A, B View Figure 49 , 58A View Figure 58 ) but can be distinguished by the pimoid embolic process with scales distally and a spine subdistally (Fig. 55C View Figure 55 ) (vs. distally with two jagged tips in P. lata , a distally trifurcate apex in P. trifurcata and P. yele sp. nov.) and also from P. lata by the finger-shaped paracymbium (Fig. 55C View Figure 55 ) (vs. with a blunt tip), from P. trifurcata by the embolus without a spine (Fig. 55C View Figure 55 ) (vs. with a short, slender spine proximally), and from P. yele sp. nov. by the broad cymbial denticulate process (Fig. 55C View Figure 55 ) (vs. short and distally narrow) and by the embolus without a spine (Fig. 55C View Figure 55 ) (vs. with a short, slender spine proximally). The female of P. jinchuan sp. nov. resembles those of P. crispa (see Hormiga 1994a: 63, figs 239-247) and P. yele sp. nov. (Fig. 50A-D View Figure 50 ) but can be distinguished by the tongue-shaped, distally curved ventral plate (Fig. 20A View Figure 20 ) (vs. triangular in P. crispa and broad in P. yele sp. nov.) and also distinguished from P. crispa by the unseparated spermathecae (Fig. 20A View Figure 20 ) (vs. separated by short distance) and from P. yele sp. nov. by the distally pointed dorsal plate (Fig. 20B View Figure 20 ) (vs. triangular with a distal tip).
