Etymology.

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

Diagnosis.

The male of Pimoa dongjiu sp. nov. resembles those of P. anatolica Hormiga, 1994 (see Xu and Li 2007: 484, figs 1-8) and P. lihengae (see Griswold et al. 1999: 93, figs 15-17) but can be distinguished by the embolus beginning at the 6:30 o’clock position with a short, slender spine proximally (Fig. 54C) (vs. beginning at the 6:00 o’clock position, without a spine in P. anatolica and P. lihengae), by having the pimoid embolic process longer than the embolus, distally serrate and with scales (Fig. 54C) (vs. shorter than embolus, with a short, sharp branch in P. anatolica and shorter than embolus in P. lihengae), and also distinguished from P. lihengae by the broad cymbial denticulate process (Fig. 54C) (vs. distally bent). The female of P. dongjiu sp. nov. resembles those of P. lihengae (see Griswold et al. 1999: 93, figs 18-21) and P. wanglangensis (see Yuan et al. 2019: 27, fig. 22A-H) but can be distinguished by the distally blunt dorsal plate (Fig. 10B) (vs. distally narrow in P. lihengae and P. wanglangensis) and also from P. wanglangensis by the unseparated spermathecae (Fig. 10A) (vs. slightly separated).
