Pimoa zayu Zhang & Li sp. nov. Figures 51, 52, 58, 59

Type material.

Holotype: ♂ (IZCAS-Ar2016), China, Tibet, Nyingchi, Zayu County, Ridong Village, 28.52°N, 98.08°E, ca. 3572 m, 30.VII.2019, X. Zhang, Z. Bai and J. Liu leg. Paratypes: 1♂2♀ (IZCAS-Ar42017-Ar42019), same data as holotype.

Etymology.

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

Diagnosis.

The male of Pimoa zayu sp. nov. resembles those of P. gandhii (see Hormiga 1994a: 73, figs 218-223) and P. nematoides (see Hormiga 1994a: 71, figs 285-289) but can be distinguished by the cymbial denticulate process with many cuspules (Figs 51B, 58B) (vs. few cuspules), from P. gandhii by the longer, membranous pimoid embolic process (Fig. 58B) (vs. almost as long as embolus), and from P. nematoides by the broad cymbial denticulate process (Fig. 58B) (vs. narrow). The female of P. zayu sp. nov. also resembles P. gandhii (see Hormiga 1994a: 73, figs 224-231) but can be distinguished by the unseparated pair of nearly rectangular spermathecae (Fig. 52A) (vs. oval, separated by ca. 1/3 width of a spermatheca).
